Study of calibration of WATT meter of 5 A capacity. This consists of calibration measurement of Known WATTmeter with unknown WATTmeter. Two WATT meters are supplied with this trainer. One of them is known to be calibrated and the other TO BE calibrated to determine % of deviation. By this method percentage deviation of an Unknown WATTmeter is studied.

(a) ANALOG PORTABLE WATT METER – 2 Nos
(b) Digital voltmeter to monitor the incoming line voltage,
(c) Digital Ammeter to measure the amount of current passing thought the energy meter.

Necessary power supplies to conduct the experiment for the measurement of power consumed. All assembled in a cabinet with all the terminals brought out for interconnecting and for the purpose of measurement.

By connecting an external variable lamp load power consumed (KWH) can be measured.

Lamp load capable of providing 5A OR Loading Rheostat load of 10A.
