Hi
I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
I wonder how i can accomplish this so the meter would be precise at any temperature ?
