A long-planned addition to the home lab. The first test went without a problem. 2 spare fuses are also included. At YT, someone complained about the difficult connection of cables. For me, it's easy without violence. But the cables are loose in the connector bushing without a mechanical locking. I'll have to work this out.
A perfect RLC meter. Very easy and intuitive to be used. Compact and nice to read.
