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.
