Review: Great meter for the - Electrical engineer .. this has all the required bells and whistles!! I wish it had a larger storage pouch to stash my breakout plug though! Worth the price!
Review: Great little clamp meter - As a pro I was a Fluke guy, but as a DIYer, I didn’t need to go that big when my 15yo meter bit the dust. Klein had great reviews so I gave it a shot when I needed something to diagnose my AC unit. Seems well built, has all the features I need and then some. Hard to beat for the price an comes with a nice storage pouch and thorough instructions.
