Electronics and technology blog    /    Materials for March 2025 year

As part of a promotional campaign, Fnirsi recently offered me a chance to review one of two devices, letting me choose between a measuring tweezer and a clamp meter. As it happens, the clamp meter caught my interest both in its own right and for a very practical use I had in mind. So today, I’m reviewing the DMC-100 clamp meter.

This story began a long time ago—I think more than a year ago, though its roots actually go back to 2023. Today, I’ll show you what it all led me to.

It all started when I ordered a couple of CL24 loads a while back. They sat around for a while, and I thought, why not build a couple of complete devices around them? So I thought about it, thought about it some more, and did it.

At the end of last year, I wrote about a 2,400 W electronic load. At the time, it was essentially a pilot unit ordered by one of my customers. After the New Year, I ordered several enclosures designed specifically for this version and decided to take it beyond the prototype stage—even if not into full production, at least to the next level.
