Can\'t get green LED meter to work
I bought a 100uA panel meter and hooked it up to an LED (yes I tried both polarities) and while shining a 5mW (or so) green laser at it I can't get any reading. The needle moves very very slightly but it doesn't read anything significant (<1uA) /ubbthreads/images/graemlins/confused.gif
Again this is an analog panel meter with 1K internal resistance according to the datasheet that came with it. Maybe the green LED laser power meter only works with digital meters due to their lower impedance?
