Great megger despite the low price.
I like being able to calibrate the needle and I like the adjustable voltage output. I had a 480v 3 phase motor that was tripping a vfd on a ground fault intermittently but would run no problem on bypass. I put this megger to it and it tested ok at 250v, very sketchy at 500v, and an apparent direct short to ground at 1000v. I was very impressed that a $200 meter was able to clearly show evidence of insulation break down. We had the motor redipped and replaced. The motor megged good at 1000v. I have been using this meter once a week for over a year now.

AWESOME
this is the coolest megger i have ever used! Easy, effective, I find shorting wires and bad motor leads with it effortlessly. THANKS!

waste of money.
This insulation tester sucks even when you turn it off the battery drains. had to install kill switch direct to battery so it won't drain...
