FAQ:
Q: What is the function of a digital voltmeter?
A: The proposed digital voltmeter, ammeter circuit module can be effectively used with a power supply for indicating the voltage and current consumption by the connected load through the attached modules.
Q: Can I build a digital voltmeter and ammeter circuit at home?
A: An interesting and accurate digital voltmeter and ammeter circuit has been explained in the present article which can be easily built at home, however the unit will require a well designed PCB for the sake of accuracy and perfection. The circuit employs IC 3161 and 3162 for the required processing of the input voltage and current levels.
Q: How to monitor volts and currents?
A: A digital volt meter and an ammeter become very handy for monitoring voltages and current perfectly without compromising safety parameters.
Q: How does the voltage/current display module work?
A: The voltage/current display module works using the unregulated supply from the supply source without any issues (not to exceed 35V max), note the point E and F in the second figure above. In that case the bridge rectifier B1 can be eliminated.
