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.
Features
1 . It combine the current clamp and the meter together, displayed
by colorful and touch-screen.
