Scr elektroniks manufactures energy meter calibration panel which facilitates testing of a number of meters say five, ten or 20 at a time with speedy testing of meters. The company supplies these energy meter calibration panel comprising power source, error display units, photo electronic sensors, fabricated panels with fixtures, computer system, software and standard reference meter. The power source provides:
A] Test current at adjustable low voltage to get any current between 0 to 50 a which is displayed on digital current meter
B] Voltage source gives adjustable variable voltage between zero to 300 v.
The voltage output is displayed on digital voltmeter while the calibration is done at unity power factor. The error display unit is a micro processor based six-digit display unit to indicate ± 100.00 to +100.00 % error.
