t o C a l i b r a t e
Connect a DC standard voltage meter which can measure up to 1000V to the output connectors
and then press the TEST button, the program will automatically generate an output of about
1000VDC and the display will show:
IR-Voltage = V
Enter Standard V-out
Use the Numeric keys to enter the standard value of DC voltage, unit V, and then press the
ENTER key to store the standard value of IR test voltage for calibration and the display will
show:
IR Voltage, 1000V OK

Calibration of AC 100mA Range
Press the
key, the program will advance to the AC 100mA range calibration of the hipot
test. The display will show:
AC 100mA, 10K

Connect a resistor about 10K
/100W in series with a AC standard Ammeter which can
measure up to 100mA to the output leads. The Ammeter should be connected to the return
lead, then press the TEST button, the program will automatically generate an output of about
1000V/100mA and the display will show:
Current = mA
Enter Standard I-out
Use the Numeric keys to enter the standard value of current, unit mA, and then press the
ENTER key to store the standard value of AC 100mA range for calibration and the display will
show:
AC 100mA, 10K
OK
