iron vane meters are still being manufactured for panel meter applications.
"simpson electric and other manufactures" they are genuine true rms responding.
a simpson 260 multimeter is not true rms responding .
I think their frequency response is somewhat limited (kHz), and of course they are nonlinear and lack sensitivity at the beginning of the travel, but otherwise they are great. I keep several for measuring odd shaped stuff.
Compare different meters on odd shaped signals when you get the chance, you'll be surprised how little truth some cheap "true RMS" meters really show. I'm not saying low quality meters are useless, but one must always be aware when the tool is used outside it's capabilities.
Anyone using tek multimeters?
