Hi,
I bought this meter today. It is already displaying 3 volts if 3 volts is applied to it. The resistance of the coil is 3370 Ohms (maybe the coil plus a built in resistor) and the current mesure .000839 Amp. when the needle is on 3 volts. These are my measurements. They are approximative.
I would like to mesure up to 8 volts. So a 6,17K resistor should do it. I will then have a reading from 0 to 8 volts. Right?
But what is interesting me it to be able to monitor the voltage from 6 to 8 volts only. So instead of 0 to 8 volts, I would like the total range of the meter to be from 6 to 8 volts.
How can I possibly be able to do that? If I can do it with a zener diode, please explain how.
Thanks!
Alain
