Amprobe 37XR-A True-rms Digital Multimeter
Amprobe 37XR-A True-rms Digital Multimeter

The Amprobe 37XR-A Digital Multimeter offers true-rms measurement along with component and logic testing for troubleshooting electronics at the bench or on the job site.


Amprobe 37XR-A True-rms Digital Multimeter is rated 4.6 out of 5 by 16.
Rated 5 out of 5 by from Great Meter The 37XR-A is a very nice meter. It has the usual features plus it measures Inductance. I will probably not use everything the meter has, as my main use is for electronics.

Rated 5 out of 5 by from Rampant cheating in RC car racing love this thing, i use it to test voltage on rc batteries (lipo) to see if people are overcharging batteries to gain an unfair advantage in a spec class. second and more important, people have been replacing motors of a specific turn, with something faster. and there is no way to visually test this....but this meter does inductance which allows me to see if the motor is actually what it says it is. the inductance is not super precise, at least not for my purpose, but it can easily tell if someone is running a 17.5turn motor or a step up a 13.5t motor...so that is awesome. biggest downside is its size....its big and somewhat heavy...i liked the dimentions of my facom voltmeter much better , and the wires where better too, but also twice the price....so the amprobe replaced my facom after someone spilled in it and left it to die grrr, but the amprobe gives me more options at half the cost so thats cool

Rated 5 out of 5 by from great product This unit is a must have for engineers and hobbyists. Inductance measurement is a key tool every person who works with circuits needs to have to quickly analyze problems, this is a full featured RMS meter. Ideal for working mix signal environments, very well designed unit, excellent construction and quality. Very good deal in highly competitive market space from one of the longest and most respected measurement brands in the industry. Best return on investment for the feature benefit delivered. Best price as well.

Rated 5 out of 5 by from Great Multimeter This meter has a real feel of quality about it, from the solid feel of the case to the nice smooth action of the range selector switch, and the bright easy to read display. The best thing with this meter is the confidence it instills in you, producing repeatable dependable results every time I use it. The only negative I can think of is the slow response of the continuity tester.

Rated 3 out of 5 by from Good meter after you fix it I don't have too much bad to say about it except for the fact that I've had to fix it twice. Both times the effect was that any of the settings connected to the voltage side would "beep" incessantly. The first time I found the issue to be the solder joint connecting the thermal resistor. The second time took hours to find and a couple more to fix. I'll admit I was ready to throw the thing out the window. The first time I opened it I simply went over the board and reflowed every major joint. That seemed to fix it. The next day same thing. So I opened it up again. Fluxed everything and reflowed. Fixed. It was getting worse, I'd put the cover on and not 5 minutes later error. I found the issue was a capacitor near the read out. As I tried reflowing the copper loosened(likely the issue in the first place) so then after some meticulous scraping and shining I finally got the bugger back in place. Hasn't done it again. So like I said. When it works it's awesome. When you're trying to work and it keeps preventing you from doing that. Man!

Rated 4 out of 5 by from 1. Error My amprobe show 1.error on Ac volt scale, and show 2 error on Ac current scale. There is no information on how to correct it. Other function is OK. I wish the manual should contains info how to correct the problem.
