● Close-link and ordinary calibration both can be used, ordinary calibration can be used to test single/three phase active and reactive energy meter (up to 0.5 class),close-link calibration can be used to test single/three phase active and reactive energy meter (up to 1 class)● The bench can test the converted quantity which is caused by negative phase, voltage unbalance● The bench can auto-calibrate starting, no load, basic error and calibration tolerance and 24h deflection.● Close-link calibration is using insulate current transformer and suitable for close-link energy meter.● The bench is using the standard power meter with comparison technology to offer the test the error of energy meters. ● The bench is using the error processor system to calculate the error of each
