6. Then it will show Figure 3-98 and press "
range, the system outputs a fixed voltage and then sets the loading current of Electronic
LOAD to 0.5A. The cursor is stopped at position [1] as Figure 3-98 shows. Enter the
current read by Current Shunt (DVM) to position [1] and press "
wait for it to end.
7. Once the 0.5A point was calibrated, it is important to turn the loading of Electronic
Load off and reconnect the DC Power Supply to current shunt whose rating is closest to
but still cover 2A. For Prodigit 7550, use 2A shunt directly.
8. Next, press "
Figure 3-99 shows for setting the loading current of Electronic LOAD to 1.500A. Enter
the current read by Current Shunt (DVM) to position [2] and press "
and wait for it to end. Use 0.5A and 1.5A for calibration, the system will calculate the
calibration factor for the low current range.
9. 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 10A. For Prodigit 7550, use 10A shunt directly.
10. For high current range calibration, press "
cursor will stop at position [3] as Figure 3-100 shows for setting the loading current of
Electronic LOAD to 2.500A. Enter the current read by Current Shunt (DVM) to position
[3] and press "
