5 Readback the output voltage of the selected output over the remote interface by
sending the command:
MEAS:VOLT? {P6V|P25V|N25V}
6 Record the value displayed on the controller. This value should be within the limits
specified below for each output tested.
7 Program the selected output's voltage to full scale value by sending the commands.
VOLT 6.0 for the +6V supply or
VOLT 25.0 for the ± 25V supply
8 Record the output voltage reading on the digital voltmeter (DVM). The readings
should be within the limits specified below for each output tested.
9 Readback the output voltage of the selected output over the remote interface by
sending the command:
MEAS:VOLT? {P6V|P25V|N25V}
10 Record the value displayed on the controller. This value should be within the limits
specified below for the output to be tested.
11 Repeat steps (1) through (10) for the remaining outputs.
