    leakage clamp meter accuracy

    hello. I'm using leakage clamp meter to investigate nuisance tripping in my house. It is a MULTICOMP PRO MP780050 that I bought early 2021. However, once I bought it the nuisance tripping stopped, so I put it down to damp in garage at the time. This looks just like the Dilog6518 (just without...

    CT clamp via WiFi across yard

    I want to get a CT clamp signal across a concrete yard. I cannot have an overhead cable, and going underground will be very expensive. Both ends will be in range of a good WiFi signal, both on the same outdoor access point. How can this be done ?

    Why does my current clamp meter show large current in gas pipe?

    Went to a house this morning to locate a fault causing the RCD in a split load board to trip. Going through the usual tests, I decided to put my earth leakage clamp meter on the earthing conductor. Here is where it gets weird: with the main switch in the off position, the meter was reading...
