4. Calibration Procedure
Before performing this section the HiPot tester must warm up at least for 30 minutes. Take
off the calibration label at the front panel and press the lock switch. After completed the
calibration, please press the lock switch again for opening the hardware data backup
protection circuit to avoid calibration data loss.
The following items are required for calibration.
 Voltage Calibration (See section 4.2)
ACV 5KV Offset (0.05kV) ; AC HiPot Voltage Offset calibration (AC Mode)
ACV 5KV Full (4KV) ; AC HiPot Voltage Full calibration (AC Mode)
DCV 6KV Offset (0.05kV) ; DC HiPot Voltage Offset calibration (DC/IR Mode)
DCV 6KV Full (4KV) ; DC HiPot Voltage Full calibration (DC/IR Mode)
IRV 1KV Offset (0.05kV) ; IR Impedance Voltage Offset calibration (DC/IR Mode)
IRV 1KV Full (1kV) ; IR Impedance Voltage Full calibration (DC/IR Mode)
 Current Calibration (See section 4.3)
