Will this measure V and I from different sources?
« on: December 04, 2013, 06:41:57 pm »
Will these Chinese digital volt / amp meters measure voltage and amps from different places? IE, measure mains input voltage to a power supply, and filament current to a valve from a transformer, in the same supply simultaneously?

Provided you use the current transformer, and your filament is driven with AC, I would say yes.

Thanks for that. Luckily I have discovered a friend who has a spare unit like this and I can borrow it and check it out. Cheers
