Calibration of PMMC Voltmeter Using a Potentiometer

Procedure for the Calibration of Permanent Magnet Moving Coil (PMMC) Voltmeter:- Give connections as per the circuit diagram in above figure. Vary the voltage across the voltmeter so that it reads a rounded position, say 5 volts. Measure the voltage across the voltmeter by ...Read More

Calibration and Testing of Single-Phase Energy Meter

Our aim here is to calibrate the given Single-Phase Energy Meter using a precession Wattmeter and stopwatch using or employing phantom loading. The main apparatus required for conducting this practical experiment include: Single-Phase Induction type Energy Meter – 240V (5-10)A Wattmeter 300V/10A UPF Phase ...Read More
