- Using This low cost Digital Calliper = PASS / FAIL = How to TEST accuracy and how to use.
By comparison a digital calliper is surely the most useful measuring tool in a shop, from machinist, to mechanics, to hobbyist, etc... We all need to make precise measurements.
Even not being the most precise tool in metrology, the calliper is the most precise tool many people will ever use.
How can we know if this tool meets our standards, by testing it according to a reliable standard, the ASME B89.1.14 is the basis on testing a common caliper. We'll test the 4 basic functions and see if this tool is good enough to be in anyone's toolbox...
We'll just get 2 birds with one stone, this caliper was given to me by Banggood for purpose of evaluation, so, by needing to make the procedure to see if it would be a PASS or a FAIL, might as well make a detalied video on how it's done, if you need to do the same for something you own or thinking to acquire, then, you can inspire yourself from this video in order to test your own tools...
====================================================
"""DISCLAIMER"""
This tool was given to me by Banggood in order to make an evaluation, this is my evaluation in real time.
====================================================
Here is the direct link to the calliper tested in this video.
Please note that the purchase price may vary depending the time of purchase, the available discounts or promotions, be sure to look for those discount codes when available.
There are also some interesting items that I personnally tested and use, those are worth purchassing since the price / quality ratio is excellent.

Thanks for the video. Just a helpful hint to whom ever was plasma cutting, It's easier and you get better cuts if you were to pull towards yourself. That way you get a straighter cut and no skipping that you would get with going sideways or forward.
Right about pulling, manual cutting combined with a straight edge makes cuts close to what a CNC table would do...
Thanks for your comment, Pierre
@@pierresgarage2687 You know, Exactly. Was just trying to help out and make things easier.
That is a good suggestion for using gauge blocks in place on a ring gauge. I am going to try this for checking my ID mics. I have been using an OD mic set to specific dimensions , but the blocks should be more accurate and also gives a larger contact surface. Thank for sharing.
Hi, it's always a treat to hear that soemone got something positive from a video, even more so when you take a short moment to leave a comment, thanks, Pierre
Thank you for the great video. I didn't really think about the pressure needed to find an accurate measurement. Keep up the great work!
Making precise, reliable and repeatable measurements isn't just a mater of having the best possible quality tool at hand, handling is also essential...
Thanks for the nice comment, Pierre
Hello
Agin thanky because of sharing your video with us.
Idont know why only igot evry time Special edveice from you also i learn soooo good.thanky maaaaaaan ilike you.

I used my highly trained eye and I have come to the conclusion that you were spot on in Your analysis.
Great video
Hi Scott, your sharp eye on my work is the assurance that everything is done properly and accurately, we'll have to call you "eagle eye"... ;)
@@pierresgarage2687 lololol
Cool, thanks for doing this, Pierre. It is good to know how much one can trust his/her digital calipers, especially as quality can vary. For the price that set you tested in this video seems to be a decent unit. I use the one set of digital calipers for a lot of what I do but as per my machining instructor, only trust it to within a thou or two, not really using it for bearing fit type work. You have some nice test equipment to verify your measuring tools, very handy for doing a real test of resolution quality like this one. Those gauge block holders would make it easier for sure and the setting rings too. Thanks for sharing!
Hi Everett, with time you end up with a pretty complete collection of toools and mesuring devices, the only thing that forgot to grow is the shop space... lol
Asian tools are as good as what we request from them, most manufacturers are doing business over there... Quality control is key to offer good products.
If you're picky enough you get good purchases for a decent price, I'm trying to get references or feed back from other purchassers before getting something, even there, nothing is 100% assured...
Cheers, Pierre
Thank you for showing this procedure. The problem with banggood stuff and chinesium in general is that this particular tool seems decent. Well the next one off the shelf going
to a poor old hobbyist who just watched this and got impressed will most probably be a real crap (bent beam, grinding dust in between the sliding surfaces etc.).
So far comment on this tool are positives, hope it stays that way, if not let me know, I'll se what I can do about it. I wouldn't want to approve something that I wouldn't use myself...
I it's a very rare occurence, it's like anything sold even by fancy brands where sometimes a sub standard item slips quality control....
But high percentage of duds is not near acceptable...
Thanks for comment, Pierre
@@pierresgarage2687 in fact My daniu caliper really sucks, different measurements values at lower jaws and upper jaws; even it is new. I have ordered it after seeing your review. It is not your fault probably.
@@tacticalsavage the unit I tested really tested great on all points, I also got a second unit that did good on measures, there was one problem on tha second unit, when sliding the full 6 inches length, the reading was erratic towards the upper limit. There is another viewer that reported that problem...
Since the was nothing to lose, I dismantled the whole unit and investigated, what I found is that the protective tape they laid on the printed scale was uneven in thickness and interfered with the reading head, I removed that tape and applied a thinner kinda tape and everything is working great since... You're the first that mention having problem with manufacturing issues like not being properly machined and controlled, have you tried getting a refund?
@@pierresgarage2687 No i did not try a refund infact, since i realized the defect 2-3 months after i bought, i was using another caliper till then. Thanks for great reviews anyway and giving idea of dismantling the unit and give it a look. Stay healthy, good days.
@@pierresgarage2687 i dismantled and reassembled the caliper, the difference dropped to 0,11 mm, better than before at least.
Thank you, boy. Thank you for showing the quality or not of these products. I would have no measuring tools and so I enjoyed this video very much, which gives us confidence when buying such measuring equipment. Thankful;
Thanks, Pierre for your comment. I like your channel, but my English is very poor. But we don't need to understand everything that is said. Just a little while the images speak for themselves. Thankful;
If you want a correct measure across longer span you lightly rotate the part around an imaginary axis connecting the jaws which is also perpendicular to them. Then you bring your part to stop in final position. That self-locates the part at the "lowest measurable" distance in the jaws.
This is a very good technique, to be tried next time a longer part needs to be measured...
Thanks for sharing your knowledge, Pierre
Great review Pierre. Mine last about three months - it goes wacky now, cannot be used. I learned my lesson.
I call the the Bic lighters of calipers.
Someone just brought me one that has weird reactions towards the end of the scale, like displaying random numbers, yesterday I played with it and discovered that the plastic covering is lightly rubbing on the cursor portion or the in other words the travelling head, I finally removed the plastic band and replaced it with thinner adhesive tape and the problem went away...
This seems to solve the problem for good, as when the plastic band, when removed and rubbed on the reading portion of the head was causing some reaction on the display...
Just to mention that I opened the reading head by removing the sticker in the back as well as the 4 screws, nothing springs out except that bronze or brass spring that adjust the tension on the glide bar, once put back together everything works perfect, no more random readings and the repeat is also flawless...
If you want to try and let me know what you find, I'll appreciate, Pierre
Mine does that as soon as I turn it on and when not sliding - Banggood said to send them a video - I'll see what they say.
Other than that while it worked it was a great caliper and liked the fractional readout.
Just keep me updated...
Will do @@pierresgarage2687
Hi Pierre - Imade this video to show Banggood - ruclips.net/video/khc6Hggnp4g/видео.html
@@pierresgarage2687
Great review Pierre. I always use a regular micrometer when the measurement must be really accurate.
Hi Harold, a caliper is an precise tool within +/- 0.001" of an inch, this is a total gap of 2 thousands of an inch...!!! A micrometer is at least ten times more accurate in skilled hands, good call...!!! KOKO, Pierre
i have had the same caliber for 6months now and i can only say good things about it...its price/quality/accuracy is undefeated :)
Even the battery is doing great on mine and it's been more like 10 months so far... 🙂👍
@@pierresgarage2687 yep...first battery still rocking hard :)
I got one also when I saw 0.01mm. I just need to work on that finger preasure. For the price is amazing tool. Mine was not as good i had a ray of light on jaws then I noticed burr on back of jaws. I cant complain for the price.
The rating is +/- 0.02 for measures under 100mm and 0.03 mm for measures above, a caliper is a great tool when it's repeatable and withing the tolerances of the work you need to perform.
If the jaws are showing "VERY LITE" irregularities it's possible to use a 5000+ grit precision small stone and hone the surfaces, beware this is a very delicate operation and only performed if you are aware that you could also ruin the tool if you fail...
For the feel, just practice with known references until you repeat all the time, get some random gauge blocks values and write your readings taken blindly... after you get good at it it won't matter if you already the value before the measurement... ;)
Good info. Great video presentation. Thank you for sharing.
Thanks for watching and for taking a moment to comment....
Very good video Pierre. That caliper came in well - most impressive.
Some good knock offs coming out of China. If people recognise the fact and pay a little bit more for improved quality it becomes a worthwhile exercise.
When BG start selling DIN standard gear as a high level option, things will really hit top gear.
Cheers Rob
Was also surprised on how the inner measurements were close and accurate, this is often one of the bigger problem with even the most eppensive calipers, the problem is to match the inner jaws to the outer jaws during manufacturing...
I've learned to be picky in choosing the tools from direct sellers from Asia, some of those tools are quite excellent, as for some others, lousy scrap not worth their weight in material...
Banggood is a little like Amazon, it's many merchants tha sell under the Banggood banner.
This is where as reviewers, we can help sorting out the crop and pick the better purchases... ;)
We still got more snow and expect MORE Rain, within a couple of days, GEEEZZz, I'm tired of this... lol
Cheers, Pierre
Hi Pierre,
I have been mulling over your statement in the previous reply "Banggood is a little like Amazon, it's many merchants that sell under the Banggood banner."
I'm not sure that is correct. I've always been under the impression it is many "brands/manufacturers" that sell through the Banggod portal/shop.
Amazon and Ebay are just a whole lot of little shops selling various stuff through one link, but I think Banggood is quite different. BG is dealing directly with the manufacturer, not some middleman like Ebay and Amazon.
I know through dealings with BG that they have direct contact with the manufacturer and supply feedback if necessary.
I think that is why they are keen to get product reviews, as it gains exposure and also helps them identify the duds.
Cheers Rob
You my be partially right about this, it seems to me it's not only manufacturers, some sellers are selling different sorts of items, like garments, kitchen accessories, tools, toys, etc, under the same roof, those are probably wholesalers or distributers, but from here it's difficult to sort it out, possible it's a mixture of all those...
I wonder if our handlers are able to clarify if we ask...
Very good review . With the reference to pressure . Makes a lot of sense for a sensitive instrument .
By practicing and with experience, you get to be much more relaxed and feel better the seating of the measuring surfaces, with all this the accuracy along with repeatability increase greatly...
Thanks for your comment, Pierre
i could watch you measure things all day - very relaxing!
Surprising comment...!!! In fact, measuring accurately is a question of "Feel", if you're able to make the measuring tool an extension of your body, you can adjust to minute details, this is where being relax is important as opposed to being stressed, stress impairs your ability to sense the subtle differences...
Thanks for your comment, Pierre
I feel stressed out. He is obviously manipulating the data even tho he says he isn't. I swear hes cheating us. 🤬
Finally something I can use my micro surface plate for!
Yap...!!! It's what we call micro surface... lol Also great for micro use...
Cheers to you down under, anxious to ship you our cold and snow and get back to warmth... lol ATB, Pierre
Winner of a video, I have been researching "what are the 7 strategies of reading?" for a while now, and I think this has helped. Ever heard of - Riddleagan Undiscovered Ability Remedy - (do a search on google )? It is a great exclusive product for discovering how to double your reading speed minus the normal expense. Ive heard some extraordinary things about it and my co-worker got great results with it.
Lots of good info Pierre. Thanks sir
This is a proper way to make a certification for caliper according to the ASME procedure, not being a certified lab don't allow deliver a certificate, but, will help validate the performance of a tool in an informal fashion... ;)
Thank you for revealing your techniques for verifying calipers. I think it's time for me to grab my gauge blocks and make some checks of my own measuring gear.
The main thing in controlling a tool is to have a decent procedure, this is why some labs will develop a way to accurately certify a certain type of tool in all it's features, there is also the handling, as mentionned in the video, you need to develop a feel for being able to do repetitive readings, this comes with some experience and practice...
Even a set of Asian imports blocks are a decent quality enough for a serious hohhyist to get reliable results... ;)
Thanks for the video.
Hi, thanks for the comment, Pierre
Of the import calipers I have used, the ones with the LR44 batteries (about $20) seem to skip counts, and do not always return to zero. The ones with CR2032 batteries (about $40) do not seem to have that issue, and the batteries, while more expensive, last longer. On both designs, the quality of the jaws and slide varies, but I think the electronics run in two types, and are all copies of each other.
So far all the lower priced imports I got ( 3 in total ) are powered with AG-13 or LR44 batteries, there don't seem to be issues with them, since most of my digital calipers are Mitutoyos, I only have a few cheaper imports, those have been quite reliable for maybe the last ten years concerning the older ones. My whole collection of calipers totals about 15+ from 6" to 40", some even being brand names are better than others... ;)
Hi,
I appreciate all your vids, always good material. This one interesting as I recently bought four of the exact same calipers for general rough and tumble use in the shop. I haven’t tested any of them as you did, but I’m encouraged by your results. We have better quality measuring tools for the jobs that need them, but again I’m encourage by what you found out about these particular calipers.
One thing I did notice about them is the relatively sloppy fit of moving parts. Relatively is the word. For the price I think they are not bad at all.
And thanks again for all your vids, I’m a fan :-)
Alistair
Hi, thanks for the very kind comment... Always a nice reward for me to hear.... !!!!
If you find them a little sloppy, you may look on the top of the carriage, there are two holes with two screws taht can be adjusted, be very gentle in playing with those, but, you can tweek the sloppyness a little, just enough to still have a smooth feel and reduce the loose feel to it...
Thanks again and I hope the fix helps you... Pierre
I have a custom step guage lab standard that was given to me. Has one inch steps from one to six inches plus a half inch ball right in middle. Has chart of exact lab measurements at a given temperature. Nice hunk of tool steel.
Don't care for the fractional displays because none of them reduce the fraction. So you get 12/32 or 24/32 instead of 3/8 or 3/4. (As I recall, might even have been 24/64 & 48/64ths).
Might buy me one of the Banggood calipers, as my HF calipers all suffer from short battery life. Something in design draws power from battery even with display off.
A decent shop needs some reliable standards to refer to, those days an Asian gauge block set is around $150 or less, and, surprisingly accurate enough for most shops...
The fractionnal of this one is intersting as it simplifies the equation to it's simplest denominator, so you get 1/2, 1/4, 1/8, etc... more usable than 128th...
Not all cheaper calipers suffer from the battery hungry syndrome, so fat this one seems all right, but, I'll keep a record on how they do, one or two batteries per year is acceptable, but, once a month isn't... ;)
Not bad for a inexpensive caliper, nicely done my friend!
Hi Ray, your collection of Wilton's is growing...!!! They reproduce when left alone... lol
Sometimes, among the import calipers there is a way to fing some real good ones for a decent price, let's hope they will keep the quality as time goes by... ;)
Amazon sells just about everything they do{different brand) price very close.A lot less wait time and a lot less trouble if you have a bad item.Just my opinion.
There are many sources to get all sorts of products, the main issue here is to be able to put our hands on the cheaper reliable ones and the better service at the time you need the product, sometimes the products are only available on Chinese sites before becoming available on the eBay or Amazon sites....
One of the important issue in this video was to show how to properly test any caliper for proper respect of it's advertised tolerances...
Thanks for viewing and for taking time to comment, Pierre
Do you by chance have the same measurement results for a Mitutoyo to compare to? Your results are impressive, I’m just curious as to how a Mitutoyo would compare. Thanks for sharing your results!
I've got about around 12 genuine Mitutoyos or other fine brands of digital or vernier calipers from 6 to 40 inches, the results are close to this, the biggest issue is the internal measurement jaws, they have to be machined really close tolerances to match with external set of jaws.
This caliper in the present test impressed me as a good tool....
Really hope they all perform in this fashion... ;)
Thank you for the comment, Pierre
I have those , I purchased them on e-bay and they are the best cheap ones I have .
Buying the cheaper calipers is not an exact science, some of those are real good and accurate, on the other hand a few I came across along the years were very poor quality, the poor quality ones are to my eyes, absolutely unusable, they'll make you ruin you work just cause of a glitch....
Make sure you test your tools periodicaly to certify their performance, this is also valid even for the most expensive ones... They too can fail... ;)
Another great video. Looks like Crappy tire has some competition.
I have to try that test on my MasterCraft callipers.
MasterCrap calipers are only a decent purchase when they come on sale, got one of the older ones, (10 years) it's stil good, got one with similar looks about 4 years ago, that one wasn't that great at all...
For some time they got a new model, haven't tested it and got no idea about how they perform...
As for this one from Banggood, if the quality keeps up it's a great buy....
@@pierresgarage2687 I think I'll try the Bangood ones. I have the old Mastercraft ones.
OK, this is silly, but I'm first. Great review Pierre.
May sound silly, but, there is a need for a first one, this time, you're the ONE... ;)

Hi, thanks for viewing and for taking a moment to leave a comment, Pierre
Nice tool for the price! And nice skills using it. 😉 I like the fractions to measure drill bits at school. Wish they didn't had the 128th resolution thou. More annoying than useful. Nice yet simple trick for the inside measurement. Comme l'oeuf de Christophe Colomb... Suffit d'y pensé
Je viens juste de découvrir votre chaîne et je m'empresse de la partagé.
Most tools by now are made in Asian countries, mainly China, even the better brands have parts made there if not the whole tool...
The main thing is to make the difference between them and choose the tools that are decent quality, so far this caliper looks like something really decent for the price.
Eh, bien merci pour les bons mots et de répendre la bonne nouvelle.... ;)
Pierre
They have a 6" digital that looks almost a twin to this one, 14.99 free shipping.3 days to receive.
Guess that there are many tools similarly built and sold all around the globe, competition is fierce, this is where the consumer needs to shop and compare...

Hi Pierre, Nice explanation on how to, a good video as allways, seems to be a decent caliper. Looking forward to see if you are trying to set the grass on fire.

Cheers, Pierre
Good review Pierre. Not sure I'd get used to the different figure sizes but despite that, they seem to come out pretty good.
Hmmm - recorded a while ago? Lack of snow ad ice!
If you need to machine something and measure, you'll get the numbers right, or, you'll have to restart doing that part, this way you learn quickly... !!!! LOL
Here, weather is Cold, snow, ice, rain, warm, reset and ready for another round of cold, snow, ice, rain, warm, reset and ready for another round of cold, snow, ice,
You must be getting the picture by now, sure if you're still reading this, you can get used to the small numbers on the caliper... Grin...!!!
Making inch measurements may mean you are getting rounding errors if the native measurement is metric. See this a lot on DROs.
I know about the conversion from metric to imperial, it will still stay well within the announced tolerances, it's more objectionable when you get to much closer tolerances and need every bit of precision to get the parts done, don't worry, soon metric will finish invading the last resisting citizens of this planet... 😉
very good review....don’t know I like the display with two large numbers and the remainders small...guess it would take getting use to.....??already green grass, where is the snow??
The green grass is long time ago... Still Freeking alternance of snow, cold and rain.... Getting real anxious for better weather, like Spring time warmth.... California Dreaming, Kind of an old song from youth... ;)

Who needs clamps when they have a Phil? :-)
Better have clamps as a backup solution, a Phil isn't here all the time, I woudn't want a Phil here all the time...!!! lol So, I got clamps...!!! ;)
The main reason for digital caliper inaccuracy is the pressure different users apply.
Micrometers have a ratchet and indicator dials a spring.

The one thing that we learn in trade school is to practice how to achieve precise and constant measurements. It may take a while but just about anyone can achieve it ....
Thanks for your comment....
The thing with the cheap calipers , they only have to read incorrectly once at the wrong time & it could cost you more than a mitutoyo absolute would have cost in the first place ! But that's just my opinion ! cheers .
Those are good for a beater caliper or for home shop owners on a budget, or anyone who don't really need aerospace precision, here I use those cheaper ones to do my roughing on parts, then, when I get close to finish or critical I switch to better tools like micrometer or similar precision...
In many situations they serve a purpose... ;)
Aside from straight up sloppy manufacturing (machined badly or not cleaned), the only issue I've had with chinesium measuring tools has been durability. They all start out measuring well, but the steel wears in normal shop use. Could I persuade you to test the hardness of the jaws vs. a name brand caliper?
Hi, you made me curious about the hardness, went in the shop and tested some calipers....
Results are:
The 6" Daniu from this review: 48 RC
Mitutoyo 8" about 10 years old: 40 RC
Mitutoyo 6" about 25 years old: 54 RC
2 times 6" from Canadian Tire: Both 53 RC ( 1 is about 4 y.o. the other one about 12 y.o. )
The finish is a little better on the original Mitutoyo's and they're somehow a little smoother, but they cost over $150 or so... The other ones are all right as beaters or as general daily use for rougher jobs... at under $15 or $20...
Cheers, Pierre
Nicely done Pierre! I am left handed as well but do not write with a "hooked" hand. Did you learn to write with a fountain pen? Most lefties that did would write with a hook to not drag their hand through the wet ink. When ball point pens replaced the fountain pen they continued to write with a hook...
Hi Fred, Remember writing with a fountain pen in the first years of school, not sure how I ended up adopting that hooked style, though...
Cheers, Pierre
You did not want to smear the ink dragging your pinky finger thru it. You never lost the hook!
Still with the hoock and writing upwards...
You zeroed when it read "-0.0005" which could have been "-0.0003" in actuality, making all the measurements off, and when "zeroed" it would be off for most measurements, but if it was "0.0001" over, it would read accurate.
Basically, I feel like it could have been accurate for all If you clean, and re-zero I think you would get better results. But still I like the video, just giving some non-expert input.
I have one, i use it over the harbor freight brand. I do not have a top name brand caliper (yet) so i dont know the difference between the two
There are many companies that have their name on different tools like calipers, some are excellent quality as others are not so great, they have to be tested by someone with lots of experience in measurements using reliable method and certified references, then you get a real idea of the tool accuracy and general quality.
Also, there is the fact of quality control, are all tools from the production going to meet the pass requirements...???
In good practice they all get to be tested before shipping... ;)
can you measure without batteries??? or it is a must (to have batteries)??
Unfortunately, you need batteries to use a digital caliper, look for cheaper bulk packages, it shouldn't be much more than 10 to 20 cents per battery for the LR-44, a little more if you get your hands on SR-44, the SR are lithium so they last longer...
I need some help. My buddy gave me an electronic caliper that looks and feels really nice. Unfortunately the original box was destroyed, and the manual along with it. The brand (i think) is called PAV Electronic. I see the serial number on the back, but no model number, nor can I find any information on 'PAV Electronic' at all really.. Any idea?
Didn't find anything about your specific brand, in just about all cases you can rely on the specs from a similar product since those tools are made from the same basic parts and specs.
hope this helps you find what you're looking for...
@@pierresgarage2687 I found out the brand is SPI. PAV is, for some logo'd on the side of it though. Swiss Precision Instrument's is what the acronym stands for
Pierre's Garage also, for some reason the only caliper I found with that specific marking is like $1,100 whereas most of their other calipers are between$ 80 and 150$. My buddies mom used them for work but has since retired and passed away. They aren't new by any means, but regardless of the fact that they sat out in a garage inside of a box that had since molded and rotted away, there's not a single spot of rust or marring of any kind so I knew they were pretty high grade. But if they are worth a lot of money, I wanna make sure my buddy knew what he was doing when he gave them to me in the first place. I doubt he would care, but still. You never know
@@Nuck-Fo0bZz
I know SPI, I even got a few tools from them, like a set of internal micrometers, excellent tools...
Making a search with the two related terms, then, I get results similar to yours, in deed there is a model that cost over $1000, the specs are real close from any other cheaper tool.
Seems like the real significant difference is the built, you may notice the V shape of the sliding surfaces, those are advertised as lapped and supposed to be real smooth operation, looks like you got yourself a very nice and worthy tool, if that gentleman really wanted to give it to you, this is gonna do you a lifetime of reliable service with a little care from your part....
Guess it's your turn to allow this tool to live a useful life until it's time to pass it along to the next one... 🙂👍
@@pierresgarage2687 yeah, like I was saying it had been in a garage for years. The box had literally rotted away with them I side of it. It took some cleaning, but once finished; well, it's now pristine to say the least, and slides as smooth as butter. It's amazing how quickly the numbers will change (down to the thousandths) while the action(or whatever its called) is sliding. Hundreds of times per second seemingly.
Anyway, I will pass it along one day if he decides he doesn't want it back. Definitely wouldn't blame him if he did. At that price point though, I figured it was probably had some kind of industry certification or something. In the food industry every utensil has to be National Food Safety certified which turns a $100 blender into a $700 blender. Why? Well, reasons of course. Lol, but seriously, certified manufacturers do it because they can.
nice fingers bro
Wish my body kept it's earlier looks, unfortunately age affects all of us differently but surely...
I would think long term use would be another indicator of how cheap vs. quality calipers or anything else for that matter stand the test of time under use, anyway thanks to the great white north and all that slipping and sliding.
I own mostly brand name calpers or verniers, with proper care and use they last for ever... ;)
About 10 years ago I got a cheaper digital caliper from Canadian Tire here in Canada ( About $12 on sale, regular price $39ish, this is over priced in my books... ) , it still performs quite like when it was purchased, the battery cover lost it's retaining tangs, though, asside from cosmetic wear, I'm satisfied with the product. Bought a second one just the same about 4 years ago, that second one wasn't up to the quality of the first one... :(
The one used in the video seems like a good candidate for a long time use if treated properly, sometimes we need to use caliperd in pretty harsh conditions, this is where it's less a pain when it fails compared to a $200 tool...
Now, let's hope they keep on the good work in the quality control department... ;)
Will the store let you do this, pointless once you have bought it.
There is nothing like asking, it only takes 5 to 10 minutes at most...... 😉👍
Hello Pierre
hope all is well
Hi Christopher, kinda on a batteries recharging break for the time being, a couple of passing away in the last 2 years, things are looking up, though...
Thanks for inquiring and I wish you a great Holiday Season... Pierre
@@pierresgarage2687 Gad your ok Pierre my condolences for your losses.
Are you French by any chance? I bought this caliper, it's pretty nice!
Canadien Français, à environ 30 minutes de Montréal vers le sud... Cet outil m'a agréablement surpris lors des tests, j'ai déjà eu des déceptions par le passé, il est bon d'en découvrir de belle qualité..... ;)
@@pierresgarage2687 Oh okay! I should have expected that because you English is too good for a French speaker, I live in France and 95% of us kind of stutter in English ahah
There are people here that don't perform so good when speaking English, if they ever know more than "How do you do...???" ... lol
I knew there was something else good about you. Lefties unite.
Hi Barry, lefties, there were a time ling ago quite when I was a kid, they were fair game for teachers to beat until the converted to right hand use, I was fortunate enough ( sometimes, maybe, not... lol ) to be "left" using my left hand...
Let's cerate an amy of lefties, then they'll make more lefty tools, cisors, mouses, electric drills ( the keep on button on the right side ), electric hand saws, etc....
@@pierresgarage2687 My dad was not allowed to use his left hand and was forced to write with his right. Draconian era that was.
Not hard to do, if the caliper comes with preprinted test sheet - IT IS CRAP!
For a budget minded amateur that has to decide if he feeds his family and buy a half decent $15 caliper or purchase a $150 caliper in order to be able to spend some quality time in his shop, or even a small business that needs a somehow reliable beater tool, the choice is obvious...
In my opinion it's not all scrap, though, I've seen some trash in the past, by having to sort out douzen of those in order to find a decent one... ( This was around 5 years ago at Canadian Tire here in Canada... )
Be assured that you're entilted to your opinion also and I'll respect that...
@@pierresgarage2687 - Thank you for you response, and I also respect your opinion. And I to as others have stacks of old carp calipers on the shelf, and I keep them there, they will never see the light of day again!
I did buy a few better one, and use them as the go-to calipers.
As you even stated there is no low warning indicator, what you should test for is how they respond at a low batt situation, most of the CARP starts to walk all over the place for readings/accuracy! Also check current draw, the garbage (and a set of good ones) goes thru batts like wildfire, on and off, no caliper ever really shuts down.
Thanks
Good idea about the low battery check-up accuracy and idle current... !!!
Bangood
Look at the spec sheet...CALLIPER. That's not a good start!
Guess that the Chinglish translater did a better job than I, at least this time....😉
Corrected for tis video, hope you found the rest of the video to be better quality and or interesting..... .😊
Shouldn't you have put "Paid Review" at the beginning of the video?
I specified it in the RUclips page I fill before putting the video on line, there is a mantion at the very beginning added by RUclips, I also made a mention in the video itself that the tool was given to me for purpose of evaluation... So far it should be clear to any viewer.
I hope I don't sound like I am being hard on you, it has just been my experience to see the "Paid Review" at the beginning of the video in the lower left side, and I don't see it.
It has been getting pretty tough finding a good machining related video here lately that doesn't have some Banggood product envolved. It should be put in the title of the video to keep those of us not wanting to watch from clicking on the link.
I don't mind your comment at all, it's respectfull and constructive.
The main goal if this video was to show how to certify yourself a caliper by using the proper procedure, Banggood gave me that tool for reviewing, so I used that tools to show the procedure, lucky for them, the tool happenned to be a decent performer.
It's nice for some people to be shown how to test tools they actually own, and, if a low priced tool is able to be a decent addition to their toolbox, it may be a good reference to eventual purchase.
As you may not like tool reviews, just abstract the given tool, you can enjoy the part about how to do the testing in respect of the ASME standard fashion.
