Calibration Procedure
8. Calibration Procedure
Before process this section the HI-POT tester be warm up at least 30 minutes. Take off the
calibration front panel. Press the lock switch, this is a hardware data backup protection
circuit, to avoid calibration data loss.
The following items are need to calibration.
Voltage Calibration (See 8.2)
ACV 5kV Offset (100V) ; AC Voltage OFFSET point
ACV 5kV Full (4kV) ; AC Voltage FULL point
DCV 6kV Offset (100V) ; DC Voltage OFFSET point
DCV 6kV Full (4kV) ; DC Voltage FULL point
IRV 1kV Offset (100V) ; IR Voltage OFFSET point
IRV 1kV Full (1kV) ; IR Voltage FULL point
