8. Now start the high current range calibration. Select a current shunt whose rating is
closest to but still covers 20A. For the Prodigit 7550, use the 20A shunt
9. Press " " to do the 7.5A calibration. The system will set the output current to
7.500A automatically and the cursor will stop at position [3] as shown in Figure 3-122.
Input the current read by the Current Shunt (DVM) and press "
