DC voltmeter is a measuring instrument, which is used to measure the DC voltage across any two points of electric circuit. If we place a resistor in series with the Permanent Magnet Moving Coil (PMMC) galvanometer, then the entire combination together acts as DC voltmeter.
Unlike our AD448 two wire voltmeter, this meter has a third wire for the measured voltage allowing for a greater range of measurement. Just connect the red to wire positive and black wire to negative to power the meter and then connect the yellow wire to the power source you want to measure, that's it!
