10.3.7. Calibration of DC 3500A Range
Press the key, the program will advance to the DC 3500A range calibration of hipot test.
The display will show:
DC 3500A, 100K
T E S T t o C a l i b r a t e
Connect a resistor about 100K/10W in series with a DC standard Ammeter which can
measure up to 3000A 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
300V/3000A and the display will show:
Current = A
Enter Standard I-out
Use the Numeric keys to enter the standard value of current, unit A, and then press the
ENTER key to store the standard value of DC 3500A range of hipot test and the display will
show:
