Programmable DC Power Supply 62000P Series Operating & Programming Manual
8. After the low current range was calibrated,
it is important
to turn the loading of
Electronic Load off reconnect the DC Power Supply to current shunt whose rating is
closest to but still cover 20A. For Prodigit 7530, use 20A shunt directly.
9. For high current range calibration, press “
” to perform 20A calibration. The
cursor will stop at position [3] as Figure 3-83 shows for setting the loading current of
Electronic LOAD to 20.00A. Enter the current (4 digits after decimal point) read by
Current Shunt (DVM) and press “
ENTER
” to confirm.

10. Once the 20A point was calibrated,
it is important
to turn the loading of Electronic Load
off reconnect the DC Power Supply to current shunt whose rating is closest to but still
cover 50A. For Prodigit 7530, use 250A shunt directly.
11. Press “
” to perform 50A calibration. The cursor will stop at position [4] as Figure
3-83 shows for setting the loading current of Electronic LOAD to 50.00A. Enter the
current (4 digits after decimal point) read by Current Shunt (DVM) and press “
ENTER
” to
confirm. Use 20A and 50A for calibration, the system will calculate the calibration factor
for the high current range.
12. The current calibration is done once the above actions are completed. Remove the load
of Electronic LOAD and press “
SAV
E
” and “
ENTER
”to save the calibrated data as Figure
3-84 shows, or press “
EXIT
” to return to Calibration page without saving.
