Sure looks like a current (amps) meter to me. Made right up the road from me too!

KEN!

500 "U" ADC?

 

[KLF]

Micro-amps. One millionth of an amp. Seriously.

Do NOT put that in your Cruiser! You will let the smoke out!

yup, it says Full scale = 500 microamps. Still not much, though. Wonder why UC would use one of those.
Yes, smoke will come out if you bring it only within touching distance of a cruiser...

Hey, it has a 20K Ohm resistor on it.

Hey, it has a 20K Ohm resistor on it.

Which means...?

 

[45Kevin]

V=IR
12=I(20,000)
12/20,000=I=.0006Amps

Did I remember Ohm's Law correctly?

If I did, then your LC will not let the smoke out.

That's it.

V=IR
12=I(20,000)
12/20,000=I=.0006Amps

But, it looks like the resistor is wired in parallel, which means we also need to know the resistance of the meter coil. This is likely a much lower resistance, which would lower the entire circuit resistance.

Do any of you have any use for such a meter?

Only as a conversation piece.

it is servings its purpose...cool find.

 

[woytovich]

The face is small, about 1.5" square, but heavier than I would have expected. Very solid feeling, not like most modern plastic meters.

Don - 2k resistor. Red/black/red - 2/0/00

Rechecked, and agreed.

Some people are too busy knowing it all to ever learn anything.

Agreed.
