7. Once the 1.5A point is calibrated, it is important to turn the loading from the Electronic
Load off and reconnect the DC Power Supply to a current shunt whose rating is closest to
but still covers 2A. For the Prodigit 7550, use the 2A shunt directly.
8. Next, press “ ” to do the 4.5A calibration. The cursor will stop at position [2] as
shown in Figure 3-113 for setting the loading current of the Electronic LOAD to 4.500A.
Enter the current read by the Current Shunt (DVM) and press “ ” to confirm and
wait for it to end. Use 1.5A and 4.5A for calibration; the system will calculate the
calibration factor for the low current range.

9. After the low current range is calibrated, it is important to turn the loading from the
Electronic Load off and reconnect the DC Power Supply to a current shunt whose rating
is closest to but still covers 20A. For the Prodigit 7550, use the 20A shunt directly.
10. For the high current range calibration, press “ ” to perform the 7.5A calibration.
The cursor will stop at position [3] as shown in Figure 3-114 for setting the loading current
of the Electronic LOAD to 7.500A. Enter the current read by the Current Shunt (DVM)
and press “ ” to confirm and wait for it to end.
