The multimeter was instrumental in pinpointing the exact nature of the issue quickly, which saved a lot of time and potential cost in motor repairs or replacement. Its accuracy and reliability in such a critical task were truly impressive. Ease of Use: Klein Tools has done a great job in designing this multimeter to be user-friendly. It features a clear display and straightforward interface that make it accessible even for those who might not be experts in electrical engineering.

    • Better than my fluke meter .
Style: Tester
Real quick , Klein is a proven company . The quality you get far exceeds the price you pay. Its display is easy to read at odd angles ( I’m an automotive tech and we specialize in hybrid and electric vehicles as well as todays complicated electronics on conventional vehicles) . The insulation test is accurate and the ranges measured by this meter are perfect for automotive by all means . THE LEADS ARE EXCEEDINGLY ROBUST . CAT 3 CAT4 safe . It is just a bit bulky but not an issue in my field . I prefer it over my FLUKE insulation tester by far . Costing hundreds of dollars less than the fluke with same accuracy and BETTER display . It also serves as a redundant DVOM . Buy it ! ... show more

    • Great megger for the price very well-built and accurate
Style: Tester
I am very happy with this purchase. This meter is built like a tank and has a good level of accuracy. I bought it solely for the purpose of testing AC compressor insulation and so far it’s worked really well. No more guessing if somethings shorted to ground or if the insulation is weak. I was really surprised to get a meter of this quality for the price point. I did go ahead and buy the magnetic strap afterwards and if you’re going buy this meter you probably ought to get it to. The Magness very strong and it makes it very convenient for hanging on AC units. ... show more

Easy to use. Quickly test electric motor windings troubleshooting or testing new motors before installation. Why pay $1000 more for Fluke.
