Martin I must say the detail and effort you put in to your videos are outstanding i enjoy the relaxed way you explain very complex things even a slow wit like me can follow and understand well done
Ok..if you look at my Amazon Store (see video details) there are a few cheaper clamp meters for around $40-$70. There is one on Amazon for $21 but I would not waste your money as the rating does not look good. Thanks for watching and posting.
I have learned a incredible amount of electrical info from your videos! Your so precise and detail oriented that even a slow learner like me can take in the info and apply it! THANK YOU SO MUCH FOR SHARING!
Very informative, as usual. I appreciate the layman's language as well. Beginners can get lost trying to keep up when too many tech terms are used. They can be learned at your leisure once you understand the process.
these videos have helped me alot in my small solar projects. i would like to find more in formation on small circuits and resistors im looking to build a solar heater with a small fan and a snap disc and a small solar panel to power it all with no batteries. im also looking into building led lights for small power consumption. thank you for all your help
Very odd...I wish I had an 87V to check this. If you post the question on the forum you will certainly get feedback on the issue. Thanks for the post and watching.
Your explanation is so great that is better than few teacher I got on my school. I'm on HVAC/R, but when we get to reading multimeter i did not get it until I watched your video. Thank you body.
On your video I see ecactly the same thing I am experiencing. At 17:55 check how long it takes to settle on the current reading when you switch on the load. That slow response not only takes any inrush current measurement out of the question, but also dampens any measurement of a varying load. Then @ 21:24 check the snappy response of the MT22 working in conjunction with the same current clamp. Thanks for the reply. I may find something more interesting to post on your forum in the future.
Another great comprehensive tutorial ! I use wireless power meters various brands.. I then can connect them to a computer and download all the data, as they offer a very large memory storage bank. So I guess for solar power they would be really great, maybe not for accuracy, but surely for trend. Thanks once again for sharing the wealth of information! And you call yourself amateur !! Wow I'm at kinder garden than LOL
Great video! Enjoyed it. I bought an Amprobe line splitter which makes using the Fluke clamp very easy for any given appliance. Costs like 20 bucks. Thanks
Great Video, Martin! Do you think we can track down a current AC leak problem of an house using a clamp? (Maybe with one current transducer with a resolution finer than 0.5A?)
Type "multimeter review" into Google, you'll see one of my videos near the top and a website call "robotroom(dot)com. The gent there provides some very handy info on little solar powered projects.
If it's for educational purposes then yes, certainly you can. I would just ask that you please leave the video intact with the banner so people know it's my video and RUclips channel. Please do not upload it to another channel or website. Cheers, Martin.
Hi Martin, According to the fluke manual for the 87 V, zeroing the meter in the AC voltage ranges is improper becuase a it says a small residual voltage is expected due to the characteristics of RMS measurements. I don't have technical knowledge of why but that is what it says in the manual
I don't mean to be negative but I don't know what kind of a person would be intelligent enough to enter a video such as this yet too ignorant to recognize the value of this video and give it a dislike. Really, a great video.
Great Videos and very useful to learn from, think I learnt more watching this video than I knew about electroics, well on this topic anyway Martin appreciate you posting these, if I may ask a question about a PCB that comes out of a old 8mm movie projector, It supplies power to the micros witches that run projector, and controls speed & Direction of the DC motor. It is getting 22volts on it's input terminals, but not outputting anymore than 2 or 3 volts on it's outputs. I can see no obvious damage to board or Cap, Resistors etc well obvious to me, If you have time, maybe you could look at the short video I have uploaded and suggest what I should be checking first. 8mm Movie Projector Speed control board no power coming out Thanks Phil

Don't use the Rel-delta mode on 87V. You got the concept wrong in the use of that button, it's not for zero-ing but to save the last reading and automatically add or subtract it to the consecutive reading. When under load that meter will display the correct reading even though it's not zero at idle. Nonetheless informative video on the types of amp clamps you use.
What would be your reaction on the danger of the frequency of 50 Hz AC where it concerns the consequences for disturbing the human hart rate? Kind regards and thanks for sharing your professional knowledge.
Ok, so you can plug clamp transmitter into any kind of multimeter? For example I own Aneng 860B+, plugging something like MASTECH MS3302 clamp will work?
I have a question...understand I am way out of my element here. I understand that it is possible to hook up the Fluke 87 to a tablet or laptop and measure/graph current usage over time? Is that so? How does one go about doing that? I have a persistent surcharge on my electrical service for a usage spike and I can't understand where it's coming from. I would like to be able to pinpoint what time of day this spike in usage is happening and then start going from building to building on the property if necessary to discover the source. Can you help me? I was recently given a Fluke 87 III but I assume it's pretty close to the same as the V you've been making your videos with. Thanks in advance, Jason
So, if I want to measure DC current, like 30A, the best thing would be to buy a clamp multimeter that can do DC current? I'm looking online to buy one, like up to 20$ (since I will use it only occasionylly) but none of those has DC current as a option... Thanx for the video
nice demonstration. The thing I don't get, is why the AC mV range on the 87V responds so slowly... I have bought both 87V and a i410 AC/DC current clump for some months now and i still can't get over that slow responce in AC current mesurement... The DC mV range is properly sesponsive so DC Amp measurments are fine. Granted, I didn't buy the 87V to use it only in conjunction with the current clamp... But it strikes me... having to buy another multimeter in order to have proper ACmV response.
how do I measure miliamps on a proximity sensor with 4 wires using a normal multimeter without the clamp? I know it has to be in series but the 4 wires confuse me I have the positive , negative and two more that say load, where should I put my leads to take the measurement? I know the range should be between 4 to 20 ma , pls give me some orientation
I realy wonder that what is the maximum frequency measurement of the fluke 80i. on datasheet it say that 100khz but I think it can do more. Please can you check it for me and tell me. thanks,
I have an outdoor thermometer sensor. It stopped working so I disassembled it and found the bad part is labeled x1 on the circuit board. Can anyone tell me what an x1 is? Any help wou It apparently has something to do with wireless communication and this is what I have a picture of. Any help would be appreciated.
I like to measure starting current from car - maybe 200-400A. Only for fun, not for accuracy. Without interrupting the circuit. I know Matech MS3302 extension for multimeter which is until 400A, but is only for AC current. Another device or how to persuade Matech MS3302 to measure DC current? O:)
Dear sir, The video was great...but i have one question......I am an enggineering student and i have to make a project , hence can u please tell me that what should i use as a power supply???........i live in India.......
I have a question with regards to resistance. I'm a robotics engineer that means I was a field engineer I don't have a degree in engineering they just called me that LOL. Recently now that I'm disabled I've been using a kiln because I've taken up pottery to try and occupy some of my time. Well, it came time to build new coils element if you will for the kill and they have to be at 10 ohms 16 gauge kanthol A1 wire. Unfortunately, I only have a very cheap consumer-grade multimeter it probably only cost 20 bucks then I have noticed that when I wrap a coil I do it on my lathe and I take it off and measure the resistance and start trimming it to get down to 10 homes it starts out at like 12 ohms and then counts down in eventually stops is that normal? Or is it that just the mark of a cheap multimeter? I'm so sick of having a crappy multimeter that I just ordered a lower-end fluke on Amazon hopefully this will allow me a little more Peace of Mind even though it is a lower-end one. At home I'm not going to be troubleshooting board-level crap so I don't need an expensive multimeter i just need a decent quality meter any tips?
Good afternoon writes Danilo Technical sell and Repair Computers in Republica Dominicana have a Fluke 289 in my work and suddenly not want to climb as if the Software is damaged, I have the test probe wants me a little hand and tell me which are the two keys to be left down to do a factory reset.
pcsoto Soto Factory Default Reset the Meter to the factory defaults as follows: 1. Power the Meter on in any function. 2. Press F4 (Setup) and select Reset using arrow keys. 3. Press F3 (Meter). 4. Press F1 (OK). The Meter should go through power up routine.
Volts vs. mV / Amps vs. mA What is the difference ? I mean to ask, which is larger : V or mV ............ Amps or mAmps ?? Is a volt 1/1000 of a mV or is a mV 1/1000 of a volt ?? Same question for Amps ??
tbh this is still messing about with cables and separating live. You could have mention live separating tool. I suppose you can mention this in your part 2b video.

Hi Martin,
According to the fluke manual for the 87 V, zeroing the meter in the AC voltage ranges is improper becuase a it says a small residual voltage is expected due to the characteristics of RMS measurements. I don't have technical knowledge of why but that is what it says in the manual
It is in a section titled "zero input behavior of true rms meters"
It says there must be a minimum voltage present to guarantee accuracy, for the fluke 87 V, it is 3% of the range, or 18mV
Thanks for a very good tutorial,enjoyed very much
I don't mean to be negative but I don't know what kind of a person would be intelligent enough to enter a video such as this yet too ignorant to recognize the value of this video and give it a dislike. Really, a great video.

Thanks vir die videos Martin ek dink jy sit great effort in en gee jou eerlikke opinie :)
Hi Martin, great video. When taking current measurements should this be on the load wire or neutral, or does it not matter. Thanks again

great videos, Thank you very much.
The fluke 43b and fluke 125 series will take the clamp measurements and convert straight to amps
Hello, Why wasn't the FLUKE 177 used for this demonstration?
Ok, so you can plug clamp transmitter into any kind of multimeter? For example I own Aneng 860B+, plugging something like MASTECH MS3302 clamp will work?

great comparison. I was breaking my head on what to buy
Mr. Martin, Great video. just a thought, if you had a spliter ...than you wouldn't need to cut the wires....
Very Nice, thanks for the great tutorials!
thanks to everyone for this video
Hi Martin, is it worth having the 87 over the 83? Apart from accuracy and temp probe, I can't see much difference, the 83 is much cheaper!
Great video 👍
So, if I want to measure DC current, like 30A, the best thing would be to buy a clamp multimeter that can do DC current? I'm looking online to buy one, like up to 20$ (since I will use it only occasionylly) but none of those has DC current as a option... Thanx for the video

what do you think about the fluke 376 true rms clamp meter? i have that and the 87v
I have 381 which is pretty much same as 376 just removable display....I love mine....
divide by 10 or move the decimal point over to the left for every 10mV/A
