Digital Dc Voltmeter Circuit Diagram. In my situation the power supply and the load to be read are one and the same ie the 2 rails of. Thirty years ago we created this circuit very difficult.
Thank you for posting the wiring diagram. The circuit as it is described here can display any dc voltage in the range of 0 1999 volts. The same principle applies to the dc voltmeter.
It would be nice to get a reading of amps supplied too.
Led digital voltmeter circuit diagram with ic7107 the voltage intended to measure is fed to the circuit through resistors and capacitors as shown in the figure. Working of this digital voltmeter circuit is very simple. To get an effective voltmeter meter range in excess of 1 2 volt we ll need to design a circuit allowing only a precise proportion of measured voltage to drop across the meter movement. The circuit as it is described here can display any dc voltage in the range of 0 1999 volts.
