300V/120A Handheld Single Phase Energy Test Meter Calibration with scanning head
GF112B 300V/120A Handheld Single-phase Energy Meter Calibrator
Procedure for calibration and testing of Single-Phase Energy Meter:-Give the connections as per the circuit diagram above. Apply 220V A.C to the pressure coil circuit by means of phase shifting transformer. Apply a load of 2 Amps by switching on the load. Note down the reading of two meters in a given period of time, say 2 minutes.
Single Phase Power Energy Meter Calibrator is used for calibration of Energy Meters, Wattmeters, VA Meters, VAr Meters, PF meters. The user can set Voltage, Current, Frequency, Power Factor etc. It is reliable and accurate hence it has demand in Calibration Testing Laboratories.
Calibration Of A Single Phase Energy Meter. The Calibration Of A Single Phase Energy Meter by Direct Loading Method & Comparing with a sub standard meter, training system is versatile self-contained modular training system useful in the study and demonstration of the procedure of calibration of a single phase Energy meter by different methods.
