Great for HVAC Techs

I've had one for 6 years now and it works great. It does only one job and it does it well. It's the easiest and fastest way to check windings on electric motors and compressors. If you don't know how to use it or what it does check YouTube.

Works good. As long as you have a good ground

Cheap, reliable and simple. Love it.

Reviewed in the United States on December 3, 2019

I've been using these at work and love them. Light weight, simple to use and reliable. This will not get down to the finer details of measuring resistance readings but will tell you where the weak spots are in a circuit. The lower cutoff point on this meter's scale is 20 Megaohms, well above levels I have seen circuits operating without tripping overloads or breakers. All of the problem circuits I've diagnosed with my expensive Fluke megger have shown less than 1 Megaohm from conductor to ground. I still love this meter, though, because it is so light and compact. I also like that I can attach the alligator clips and leave one hand free to wiggle wires in the conduit on intermittent problems while I press the test button with the other. I have thus far not misdiagnosed a motor with this meter but I usually go get my Fluke 1507 if I am in doubt. You will love this megger.

Great help for the diagnostician

A small price to pay for the info this can provide in problematic situations. Intermittent or rare failures can be the most vexing to troubleshoot. This helps with that analysis, it will find faults that even a good multimeter and physical inspection will miss.

Needs better leads

Reviewed in the United States on March 16, 2024

The meter works very well for megging out industrial motors. The LED readout is fairly accurate. Side by side comparison with a Fluke 1507 showed results that were close enough. I’m only checking for grounded motors anyway. The test leads could be better quality. The meter case seems fairly rugged and would withstand rigorous use. The case is very lightweight and flimsy. At best, the case would protect from dust and scratches. A thick rubber holster and better/longer test leads would make this meter perfect!

Since purchasing and implementing this check on every ac call, I have sold several systems that I would have deemed ok before. What a game changer. Paid for itself the first time I used it
