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.

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

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!
@jeffanderson13114 жыл бұрын
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
@jeffanderson13114 жыл бұрын
It is in a section titled "zero input behavior of true rms meters"
@jeffanderson13114 жыл бұрын
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

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

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.

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?
@kaynd11 жыл бұрын
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.
