Introduction:
-For electronic or inductive single-phase watt-hour meters (1.0 level and below).
-Wide calibration range with biggest current 100A, the only domestic big-current portable calibration device.
-Micro-computer controlled, once constants and turns of the calibrated meter are input, all errors in measurement range can be calibrated.
-High reliability, overload protection.
-Parameters of voltage, current, phase , power and working frequency can be read directly.
-Digital-control photoelectric collector.
