2 Turn on the power supply. Select the high voltage range (20 V/1.5 A)
[1]
and
enable the output by sending the following commands:
3 Program the output voltage to 0 V and current to the full-scale rated value (1.5
A)
[1]
by sending the following commands:
4 Record the output voltage reading on the digital voltmeter (DVM). The reading
should be within the limit of 0 V ± 10 mV. Also, note that the CV, Adrs, Limit,
and Rmt annunciators are turned on.
5 Read back the output voltage over the remote interface by sending the
MEAS:VOLT? command.
6 Record the value displayed on the controller. This value should be within the
limit of DVM ±5 mV.
7 Program the output voltage to the full-scale rated value (20 V)
[1]
by sending
the following command:
8 Record the output voltage reading on the digital voltmeter (DVM). The reading
should be within the limit of 20 V ± 20 mV
[2]
or 60 V ± 40 mV
[3]
.
9 Read back the output voltage over the remote interface by sending the
MEAS:VOLT? command.
10 Record the value displayed on the controller. This value should be within the
limit of DVM ± 15 mV
[2]
or DVM ± 35 mV
