Review: Beautiful display- Very professional looking - These work great and look great too! Just bought another one for another project. Accurate and bright. Fits perfect into a 3P breaker enclosure.
Review: nice little meter with a bright color display - I like this meter. The colors show up well even in bright outside light. I'm using several of these to measure the output of my solar inverters. As the instructions state, it doesn't matter which direction the current is flowing. It will measure in both directions, just not differentiate between the two. They also fit well among other DIN breakers.
