voltage and current of the scale under test (refer to Table 3-4).
OUTPut:RANGe 16V (command 1)
APPLy 16.8,10 (command 2)
OUTPut:STATe ON (command 3)
2)
The electronic load is still in short-circuit mode. Make sure that the power
supply is in CC mode. Read and record the measurement value (U

) of the
multimeter. Calculate the current I

3)
Send the MEASure:CURRent? command via the remote interface. Read and
record the returned current (I

Press 32V/5A at the front panel and repeat steps 1 to 4 to test the
programming and readback accuracy at 32V/5A scale. The commands in step 3
and step 4 should be replaced by the following commands respectively.
