4 Record the output voltage reading on the digital voltmeter
(DVM). The reading should be within the limits of
0 V ±10 mV. Note that the CV, Adrs, Limit, and Rmt
annunciators are on.
5 Readback the output voltage over the remote interface by
sending the command:
MEAS:VOLT?
6 Record the value displayed on the controller. This value
should be within the limits of DVM ±5 mV.
7 Program the output voltage to full rated value (30.0 V) by
sending the command.
VOLT 30.0
8 Record the output voltage reading on the digital voltmeter
(DVM). The readings should be within the limits of
30 V ±25 mV.
9 Readback the output voltage over the remote interface by
sending the command:
MEAS:VOLT?
10 Record the value displayed on the controller. This value
should be within the limits of DVM ±20 mV.
CV load regulation
This test measures the immediate change in the output
voltage resulting from a change in the output current from
full to no load.
1 Turn off the power supply and connect a digital
voltmeter between the (+) and (–) terminals of the output
to be tested as shown in
Figure 1- 1.
2 Turn on the power supply. Select the 30 V/4 A range,
enable the output, and set the display to the limit mode.
When the display is in the limit mode, program the
output current to the maximum programmable value and
the voltage to the full rated value (30.0 V).
