” will perform 4.5A calibration. The system will set the output current to
4.500A automatically and the cursor will stop at position [2] as Figure 3-121 shows.
Input the current read by Current Shunt (DVM) to position [2]
and press “
ENTER
” to
confirm. Use 1.5A and 4.5A for calibration, the system will calculate the calibration factor
for the low current range.

Now start the high current range calibration. Set the current shunt whose rating is
closest to but still cover 20A. For Prodigit 7550, use 20A shunt directly
.

” will perform 19.5A calibration. The system will set the output current to
19.500A automatically and the cursor will stop at position [4] as Figure 3-123 shows.
Input the current read by Current Shunt (DVM) to position [4]
and press “
ENTER
” to
confirm.
