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 4Record the output voltage reading on the digital voltmeter (DVM). The
reading should be within the limit of 0 V ±10 mV for output1 or 0 V ±25 mV for
output2. Also, note that the CV, Adrs, Limit, 20V, OVP1, OVP2, OUT2, 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) for output1 or (DVM ±25 mV) for output2.
7 Program the output voltage to the full-scale rated value (20 V)
[1]
by sending
the following command:
8 The reading should be within the limit of (20 V ±20 mV) or (60 V ±40 mV) for
output1, or (20 V ±45 mV)
[2]
or (60 V ±85 mV)
[3]
for output2
9 Read back the output voltage over the remote interface by sending the
MEAS:VOLT? command.
