Hello, I have 3V DC analog panel meter.
The problem is that the meter can be connected with reversed polarity and should not overscale to the other side.
So the circuit should reverse polarity automatically.
The circuit should not impose voltage drop either as the meter will be showing wrong voltage.
Can you experts please help?
