A perfect replacement for my old multimeter that had served many years of service, but by using it I had it set for the incorrect range at the time I was using it, and fried the unit. The price was just right for the well known brand name.As a trained electrician a number of my hand tool,s are the same brand. I used the new multimetter to check the frequency and output voltage on my portable generator, as I had just replaced the carburetor, it needed a little adjustment as the RPM was to fast.

This meter did the trick. It’s easy to use and feels pretty sturdy. I’ve not tested it against my TrueRMS meter at work, but it seems accurate enough that I’ve not wanted to.
