Thanks. I didn't know a hot wire meter existed.Here is a very unusual meter.
It is a "Hot Wire Ammeter"
It takes about 1 - 2 seconds to reach a mid-scale reading, but it is very accurate.
The pointer moves when the current heats a platinum and iridium alloy wire.
it can measure AC or DC.
It's a really cool meter ... and it's BRASS.
