Thank you for showing one of these meters working on an in series test. I've been looking for to see one of these and all I find on here are people with ESR meters testing caps out of series which defeats the purpose. Thank you again.
Great video. Clear video and good lighting unlike a lot of videos of blury things you cant even see. Youve done your research and helped me with this new meter. I have a lot of old consoles to repair and guarantee there are some bad caps but I dont want to replace them all if unnecessary to do so. Thanks!
Você foi o único que demonstrou o aparelho na prática, gostei bastante do seu vídeo, Parabéns. Sou brasileiro.
You were the one who demonstrated the device in practice, I really liked your video. Congratulations I'm Brazilian
I really liked your pronunciation, man. It helps to understand what is said. Thank you. Another subscriber from Brazil.
A couple of points. First the chart is very ballpark, you need to look at the data sheet to know if the cap is really OK, but for this kind of troubleshooting might be close enough. Second point is that you NEED to zero the probes, especially with those long ones. If you didn't zero them out then the ESR could be way off. And ESR can be such a finicky thing that usually probes for the meters use more than one wire to help minimise the effect of the lead on the reading.
In general that might not be too critical for general troubleshooting but switching power supplies use low ESR caps so it's a bit trickier.
Someone mentioned the multi testers that are so cheap. They work well BUT you need to press the test button each time so you can't do the kind of probing he is doing in the video. With in circuit testing you really need the meter to test constantly so you can keep both hands with the probes.
Good Info ^^^^
You should go into voice acting! Your Woody Harrelson impersonation is spot on!
Exactly what I need. Glad I bought the right meter for the job and this video demonstrates how to use in application ! Thanks !
Fun video! Now I know how to repair my burned out $1 LED bulbs!
The $15 ebay delivered capacitor tester kit that's fun to assemble works great. It has a similar screen as yours but it also tests resistors, diodes, transistors and more. You just solder the kit together and go to it. I've used mine to test thousands of components and it works flawlessly. It even has a frequency counter mode.
Thanks for the heads up
I have one of those meters and it works just fine.
Cheers for the in circuit testing. This is just what I need.
Great example of in-circuit testing. Thank you! Looks like a great meter and has helped me decide.
Thank you very much. This is helping me in my decision to buy an MESR-100!
Love your life examples. Now I understand how a eat meter work. Keep it up.
Simple, straightforward explanation. Excellent.
I have same meter, it works great. Warning it is far safer to discharge capacitors with 10,000ohm 10 watt or larger resistor, use bigger resistor for bigger caps. Shorting a cap with a screw driver or jumpers is a direct short that can damage other components in cicuite from big current voltage inrush, can cause arc welding screw driver to cap or shocking you or melting wires or even kill you. Be VERY careful discharging capacitors, and especially large ones, you can they can store huge amounts of lethal power for long periods of time. Fir example a camera flash capacitor can be lethal. Be very careful discharging caps to properly to limit current with properly sized resistor and proper wattage rated resistor. Be careful, if you do the math on larger cos to control discharge current and voltage.
I had no idea that Woody Harrelson was into electronics repair. Nice video, I need one of these!
it read 9.1 with supplied wires and would have in circuit had you used them in the 1st place. I watched longer because you tested a led bulb, good job on the video
Is there a reason simple leads can not replace supplied alligator clips?
I bought this last year and hate it. It will not stay zeroed out. There are much better ones available.
Thanks for moving right along and making the video an appropriate length. Perfect.
It looks like a great value. The only thing I'd add is the Atlas ESR70 also tests the value of the cap at the same time, and will discharge caps before testing. So it's quite handy for refurb and testing.
Very well done I'm new to this and as you I have a few expensive electronics not working.Looking for test equipment that won't break the bank.Thanks
Great very simple video, learned how to use my meter due to this. Thanks. Lou.
Love it....but the cables are way to short ! How do you test a cap where the range is not listed on the tester ?
Hi FunBubble, i have your same device with short probe...so when i try a probe more than 20cm that tool
show an "error" when i try to set the "[zero]" cause the probe have 0.7ohm.
How did you manage to use long cables/probes ?
Regards
Alex (it)
Thanks for sharing ,I have four war meters ,Yours is a nice,one I been looking at them ,bought I have a nice restored knight kg 670 vintage capacitor tester it's amazing ,I can test for so much more with it at voltage ,test for shorts and many other things .some things seem vintage equipment works great .
Great video! Nice all around explanation.
thanks so much you explaned this meter perfect we all need help some time thanks again xxx
Awesome video! Gets me excited just need broken things and tools!
Hired would I test a 390ohm resistor that is in circuit in my vehicle cluster. Can't or don't want to take it out if I don't have to. With an ear meter
You should probably use a resistor to discharge the caps!
good video man i got one of those testers bur really couldn't interpret the readings thanks
Thanks for the info,I have four of these meters,one factory model,two different models with out case and one kit,they are handy ,I like yours too,is your rechargeable ,I only seen one that was
Got mine off aliexpress, awesome piece of kit!
You should be zeroing out the meter before testing. Especially if you are using longer probes with more resistance. You simply short the probes together and press the "zero" button. This will compensate the resistance in the probes so it isn't added to the resistance in the cap.
I ordered this meter, too, it's in the mail and should arrive in a couple days. I'm hoping to fix a tv with lines across the screen and other electronics. I figure spending money on this tester would eventually pay for itself instead of taking things to repair shops or just replacing them entirely. Thanks for the video and explanations. It looks pretty easy to use. Can't wait to be able to test "in-circuit" instead of having to remove each and everyone capacitor to test it. Just curious since you posted this video in October 2016, how's the meter holding up? It's still working fine?
hi, the esr meter is still running like new. its been useful for testing and fixing many many devices. thx
@@FunBubble Thank you, I appreciate you answering! Glad to hear it's still working after a few years. Hopefully I can get several years out of mine, too! Try to have a good week!
The chart is a very vague guideline. Always look up the capacitor data sheet. The numbers from the chart are very high..
You should discharge caps with a resistor, as suddenly shorting them out with a screwdriver can stress them.
very well presented
Friends, this fault occurs when measuring a capacitor without having downloaded it before, inside it has a protection diode D1, short and give this message, replace it and fix the tester, read the user manual
Thank you. I need one of these!!!
I ordered one. Lol
Gud day sir, I have that kind of tester, the problem is, the test prod very short, I try to change the long arm, but the resistance is defirent
need one tks any with ESR+ Capacitance Meter ?
is this meter valid for reading esr of parallel in circuit caps?
great closeups. So do I understand one can read cap values in circuit?
Yes, but not very accurate. Big error margin.
Screw driver for discharge is very bad practice as sudden discharge can ruin the cap you are testing... you should use a resistor with insulated alligator clips to properly discharge the cap... not so much for these little caps but for the bigger ones not only could you ruin the cap, but you may hinder your ability to maintain an erection for a bit after you get the life shocked out of you doing this with a bigger cap lol. You should always pull the suspect cap out of circuit before testing as your values can drastically change... you should also use flux when desoldering as well as soldering as it removes oxides and transfers heat, along with a sucker or braid. You're on the right path... just keep researching and before long your neighbors will be at your door asking to fix their tvs lol I can tell you that since I learned how to fix electronics i know for certain I will never be broke. Spent 110.00 total on all my gear to start and within the first month made enough to replace it all with 1000.00 worth of higher end soldering gear along with a microscope. On a slow month of side work fixing stuff for people with posts on social media I can make 1000.00 or so a month and on good months I've pulled in 6 to 7000.00 and that was still not back breaking work... just allotted 2 hours of time after work every other day or so. It's not only a fun hobby but it gives you an awesome sense of accomplishment... look how happy you were that you fixed the light... it's so rewarding because you know it's something so few can do. Drives me Nuys when people complain they have no money when they can easily look on you tube and learn a trade fairly well in no time at all such as this. Good luck with your future repairs!!
Nice comment.
Do you have any pointers on how to find electronic schematics? Thanks
New to the channel. What has been you experience using this tester. I've noticed some that are more expensive and wanted to know the quality of this unit.
How did you get yours to turn on and do stuff? I put in two new fresh AA alkaline batteries, pressed the power-on button and it does nothing. I took my batteries out and tested them good. Oh wait I think I see the problem now! "Made in China".
Did this meter come with both type of test probes? Thanks
Just a note. It doesnt tell you for 3300uF or 6.3v and many other ones like I think 580uF ... Thought it was gonna be good for motherboard testing, but it just gives me a reading that I have no idea is it any good or not?!?! How am i supposed to know, is there a graph for ones 6.3v and others like 1200uF and so on??? Thanks
Hi AdrianM. You can usually look up the cap manufacturer and they will give the resistance readings for given capacitors tested at 100kHz which this meter uses.
Will it test rectangle things too? The rectangle things are by these other square things with 8 legs they say OPA-637(2), and the other 2 say MUSES01.
I threw it out it's probably no good.
a very common cap is 2200 uF, why's it not on their table ?
Great Work..
awesome video and explanation!
tHANK YOU. FAST SIMPLE VIDEO. I'M SOLD. cERTIFIED yOUtUBE eXPERT!
Muy bueno el video gracias
Hola lo recomiendas
This test is not conclusive. Caps are to be measured under real working conditions. This meter may show a low ESR and capacitance within spec, though it may fail under load. Obviously, when this test shows the cap is "bad" then it is.
What if im testing caps the arent on the ESR Table? Like .47uf 50volt ?? I havent seen any tables with these . thanks!
a 4.7uf 50v cap is 3.0 esr. a 47uf 50v is 0.5 esr. im not sure about .47uf. i did a google image search for esr chart and printed out one that has more listings than the sticker on the meter. other than that u can kinda estimate by looking at the closest ratings.
That's the problem - it doesn't test small caps
I just watched a video where the guy fixing a vintage synthesizer just knew to change the small caps connected to the pins of an IC on a board not working correctly - no tester, just instinct and experience - he changed the small caps without testing them and the fault was fixed
Done some digging and it seems some can test down to 1 micro farad
Thanks for the video!
Great vid! Thanks
Have you seen a list on what a 0.47uf 50v capacitor should read on this meter?
ive got a second esr chart that is more general and it shows a 0.47uf cap should read 6.0 OHMS or lower. the chart doesnt list voltages. maybe try to find a cap of the same value and compare them with each other. good luck
@@FunBubble Ok, thank you! I appreciate the help!
Do you recommend the meter? I'm on the fence on buying it. Seems like a good tool!
Your link doesn't work. It takes you to Amazon but not the product.
Cool video. I just got my MESR and I too find the test-clips way too short. So, I used some test-leads I had, but now the MESR can't zero, it just says "zeroing error" and I've tried with other test-leads of varying lengths. Also, my MESR emits a faint but audible high-pitch sound - so, what do you think of all this? Is it defective? Should I return it? Please let me know, as I am a noob, at all this. Keep making videos. Cheers!
That's expected.The resistance in the wire will increase if you lengthen the test leads. That's why they're kept short.Btw,what's the max capacitance value this meter can be tested on?
Ok, but you are NOT using short test-leads [there's a video on RUclips, where some fellow is using 1 meter long test-leads, on his MESR without problems] and you have no issues zeroing. Also, your meter doesn't emit a sound, does it? Oh, and I believe the maximum capacitance is 100 Ohms, hence MESR - 100, but I could be wrong.
thanks
I dont understand, the meter read wrong value yet you only based on its resistance reading on the chart
Good video, thanks :)
Please use an isolation-transformer for such tests. You know, the hells door is fast open.
It is a static test (unpowered) no need
@@paulargudo9854 You tested the led unpowered? I saw in the video, when you pluged it in the wallsocket! Thats the reason, i told you, use an isolationtransformer.
Hope you dont do this "screwdriver discharge" method with 400v capacitors 🙄
The large flash indicates that it is discharged and ready for testing. Here, try this 650 volt. LOL
Sir how to esr tester mega 328 that is better
i couldn't understand your question, but i think you're trying to ask
is the M Tester / MEGA 328 better than the MESR 100
the answer is this
the Mega 28 M tester IS A COMPONENT IDENTIFICATION TESTER
one of it's functions is TO TEST ESR ON CAPACITORS
it gives the ESR reading
it gives the capacitance reading
now the MESR 100 tests capacitors
IT IS AN ESR TESTER, only
It won't tell you the capacitance of the capacitor
it won't identify components for you
IT WILL GIVE YOU AN ESR READING THAT IS MUCH MORE ACCURATE THAN THE M TESTER
so, basically they are 2 completely different things you can't compare them side by side like that.
What is the model number of this tester?
MESR-100
Hello, you do not know things other than 100, or thank you for your statement
what brand is it ??
Chinese.
Jingyan
this is a discontinued item please recommend another ?
search ebay for mesr v2. i just checked and theres bunches of them, the price has gone up tho, now theyre going for above $60
Cheap on aliexpress. Got mine the other day for €45 delivered. Think banggood has them as well
For $54 bucks I am getting one .
NEVER SHORT A CAPACITOR IN CIRCUIT!
can you test voltage with a multimeter first and if read near zero is ok to test it out in circuit for ESR if not then proceed to remove to short and then test?
@@TsunamiUndine testing ESR in circuit is safe. Short circuiting a capacitor in circuit is never safe.
@@TsunamiUndine for added clarity, there's no reason to charge up the system to test esr. The esr charges the capacitor in circuit itself...and safely. Do not add any external power sources. Do not use the esr meter then try to short circuit the capacitor in circuit to "empty it".
This is a very good meter, I've used it on countless capacitors and tested this meter against other meters, both cheap and expensive
IN MY OPINION
Compared to the cheap ESR meters and Components testers
THIS NEEDS TO BE UNDERSTOOD
1. this is a dedicated Capacitor ESR Tester
2. it blows the component testers out of the water, however it can't identify all components ONLY CAPACITORS so... take that with a grain of salt
and
3. cheap component testers like M TESTER have a time and a place
now
Compared to $400 ESR Meters, of course this does not beat those meters, HOWEVER.. IT PUTS UP A FUCKING GOOD RUN FOR IT'S MONEY
i reckon, if you can't afford a $400 fluke, buy this little thing, IT WILL SERVE YOU WELL
Hi. Can this meter test capacitors higher than 10000uf?
@@stallion63m35
OF COURSE IT CAN
it can test, for example, 1,000 uF which is a greater value than 10,000 uF
it can test , for example 10uF which is greater than 10,000uF
or..............
were you meaning to say , can this meter test values SMALLER THAN 10,000uF ?
but you also need to understand something
Unlike the MTESTER which gives you the capacitance reading , THIS METER DOES NOT.
this is an ESR tester, ok
it measures the Equivalent Series RESISTANCE
as for the range.
here is a manual with specs
www.rmccurdy.com/stuff/ESR/MESR100_MANUAL_PDF.pdf
and if it helps
i have measured cap values from
0.1uF , 50V to 4700uF 50V
i have had no use to measure caps outside of this range to this day
and on that range, the meter worked beautifully
hope that helps
let me know if you want anything else, or something tested, i'd be happy to help

Thanks for all the great information! You answered my first question when about measuring caps below it’s stated minimum range. That’s great to know, because I was worried about measuring smaller caps.
I put together a humble lab of equipment, most of which was broken that I had to fix myself. I still don’t know that much about equipment… And I think this would be a great addition because it does everything IN CIRCUIT. I have a Sencore LC53 cap leakage tester, and also i built a low-voltage leakage tester that was designed by Mr. Carlson’s lab (on RUclips.)
But they don’t test anything in circuit, which is a huge pain in the butt. A lot of times I’m not fixing older gear… And don’t need to replace a lot of capacitors. So if it’s a newer device and just has one faulty capacitor… I don’t want to remove them all to test or replace. That is so inconvenient. So I have to add a in circuit tester to my set up. I’ve been considering the EDS CAP ANALYZER 88A.... it was offered by the EDS company years ago… And as an in circuit tester that a lot of people said was wonderful. The circuit boards can be purchased on eBay so that you can build your own… And apparently it’s head and shoulders above any in circuit Tester even The one in this video. I forget why it’s supposed to be so much better… I think it has something to do with testing under high frequency or something.
What about the M tester? I have several of the multi function component testers, Dating back several years ago when they first started offering them everywhere on eBay and Banggood… And Now have a few of the modern $30 ones with the color screen and rechargeable battery. They’re great testers and come in handy every day! Truly a great piece of innovation! But I have a few questions regarding them. And hope you might know.
Do you think they will ever offer a multi function tester that can test caps in circuit? I don’t understand why the multi function tester won’t test in circuit or offer that at a higher price… It already tests ESR and everything else. It is an absolutely amazingly accurate little device.
Even though I have a few bench top LCR meters, And all types of other decent gear… I find myself reaching for the M tester more than most things.
So I wish they would combine it with the device shown here, Even if it was $100…
I was considering building a bench top version of the multi function tester. I wish they offered that choice.
Basically just putting it in a benchtop enclosure, possibly adding a larger display… Maybe I could put this in circuit tester in the same enclosure or maybe a small enclosure above it.
Since I do on my work sitting at the bench, it’s a bit inconvenient to have a little handheld device and leads that I have to pull out of a drawer or that flops all around the bench kind of in the way and doesn’t stack with the rest of the equipment.
Any answers or thoughts you might have will be greatly appreciated!
Hopefully soon they will offer a multi function tester with a nice larger sized color display, in a bench top enclosure... that is capable of ESR in circuit testing. Man I would pay good money for one of those

Hi mate
1. I want you to know i have seen your post
2. i am going to reply to you, but i've been a bit busy,
3. Give me an hour or two and i'll give you a proper answer, SPEAK SOON
@@hullinstruments
Hi mate, let me address some points that you made
1. "Thanks for all the great information! You answered my first question"
You're Welcome, Glad i could help
2. "I put together a humble lab of equipment, most of which was broken that I had to fix myself"
well done, that's the best way to do it and the best way to learn
3. "I put together a humble lab of equipment, most of which was broken that I had to fix myself. I still don’t know that much about equipment… And I think this would be a great addition because it does everything IN CIRCUIT.

Firstly, OF COURSE I KNOW MR CARLSON'S LAB , Who doesn't :P
yes, not being able to test ESR in Circuit is a pain the arse and very time consuming.
if you still don't know much about test equipment, I SUGGEST TO DO THE FOLLOWING
- Pick a piece of Equipment, let's say a Digital Multimeter
- Pick a really high end one, let's say ROHDE AND SHWARZ HMC8012 (approx $2,000)
- GO THROUGH THE DATASHEET AND THE SPECS AND LEARN WHAT IT ALL MEANS
- Now. Drill down to a multimeter that is around $1,000, then get one that is $700 then look at one that is $500 and $300 and $100 and $80 and $50 and $10
you'll find that at some point you'll see a clear difference in quality above a certain price range and you'll also find that sometimes a $500 Multimeter can do what a $1500 one can do
so , start there and learn what all the specs mean
the more you learn , the more you'll understand about what you need to know
4 Re the meter that you're looking at ... EDS 88A
here is the video i used as reference
ruclips.net/video/hTkLC9iHhmA/видео.html
HERE ARE MY THOUGHTS
a) that chart down the bottom that is supposed to be THE MOST IMPORTANT PART is going to be useless as dogshit, TRUST ME ON THAT
here's why ....
Capacitors ESR is not a standard, When you consider
Quality of Cap
Brand of Cap
Value of Cap
Mate, you can have let's say a 10V , 1000uF Sanwa, Nichicon , and let's say 5 other brands and they can all give you different ESR's
this is why you can't trust that chart
here is how you get a chart that you can trust
YOU MAKE IT YOURSELF, Based on
- new capacitors
- Datasheets of the new capacitors
- testing the average of multiple capacitors, let's say you test (for example) 100 caps that have a value of 10V, 1000uF now, ... after testing them all it will become apparent what THE AVERAGE good reading is .
FYI, in my experience (Across thousands of 10V, 1000uF Caps) i have tested that GOOD = ESR Between 0.00 to 0.06
so now, let's say that a good cap is up to 0.10
well... do i really care ?
NO I DON'T, because i have learned that i can get good caps between 0.00 to 0.06 so why should i get a cap with a higher ESR (when salvaging, of course)
so basically, you build your own list, i can get you started if you need a list FYI
next.... your meter does not have a numeric display it just has lights, which, in my opinion is not very useful, IF I WERE YOU I WOULD NOT GET THIS METER (primarily because it doesn't give you a numerical ESR Value so that you can determine which cap is which,
5. "And apparently it’s head and shoulders above any in circuit Tester
"
I highly doubt that
Rohde and Shwarz have these meters in the thousands of dollars that are above the rest.
keysight has these meters for $700 which will shit on the meter you are buying
the one you are buying doesn't even have a display, my MESR meter (just to name one) is better
hell... the M Tester is better than the one you're looking at
Here's the keysight FOR YOUR CONSIDERATION
ruclips.net/video/TXTjmUgv5Gc/видео.html
6. "I think it has something to do with testing under high frequency
or something." hehe
yes, something like that
so.. basically to reliably test a capacitor FOR STABILITY you have to (in a sense) Give it an enduarance test, this is done by running certain frequencies through the capacitor and seeing how the cap responds
so basically.... all the ESR Meters do this
the difference is
- NOT ALL OF THEM SUPPORT ALL THE FREQUENCIES, some do only 1 frequency (which is ok, , but more is better)
- some meters are not built reliable and other are
7. "What about the M tester? I have several of the multi function component testers,"
The M- Tester IS A COMPONENT IDENTIFIER but can be used as an ESR Meter
but.. FROM MY EXPERIENCE, you will find the M Tester more useful on caps OUT OF CIRCUIT
again,... you get what you pay for
However the MESR meter which specializes in ESR measurement and is not an all rounder tester is much better
8. "Do you think they will ever offer a multi function tester that can test caps in circuit? "
they already do, check out the keysight link that i gave you
9. "I find myself reaching for the M tester more than most things."
that's because tha'ts what you're used to
but as you get better in electronics you'll find yourself reaching for other things
10. "Man I would pay good money for one of those"
well, there are really expensive ESR meters out there if you want to burn money
but, teh question is this
- WHAT ARE YOU REALLY DOING ?
- DO YOU REALLY NEED AN ESR METER THAT IS GOING TO COST YOU $700 OR MORE ?
at the end of the day you just want to know IF THE CAP IS GOOD
and YOU WANT TO KNOW FAST
and YOU WANT TO KNOW RELIABLY
and YOU WANT TO TEST IN CIRCUIT
you can do all that with the MESR 100 ESR Tester
Hope all this helps
You didn't say where you bought the meter
ebay. it was a seller from china, took 3 weeks for meter to arrive. $44 with free shipping was the lowest price on ebay at the time. thanks
I’ll be damned
You can not test devices inside the circuit. The readings are not true because you are measuring the circuit too.
Wrong.
ESR meters are specifically made for testing in-circuit.
Never mesure a component in a board
That is made in china
