High Power DC Electronic Load 63200 Series Operation & Programming Manual
B. The current shunt range is 250A. Input the resistance listed in Table 12-6 and press
LOAD ON/OFF to start the Load. Refer to the DMM (V) value and adjust the DC Power
Supply value to be the same as the previous test model, and then wait for 30 seconds.
Record the DMM (V) voltage passed through the Load input terminal and the DMM (I)
reading of shunt current. Use DMM (V)/DMM (I) to calculate the resistance and check
for the value that meets the specification.
