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.
