Constant Voltage (CV) Verifications
Constant voltage test setup
If more than one meter or a meter and an oscilloscope are
used, connect each to the (+) and (–) terminals by a
separate pair of leads to avoid mutual coupling effects. Use a
coaxial cable or shielded 2- wire cable to avoid noise pick- up
on the test leads.
Voltage programming and readback accuracy
This test verifies that the voltage programming and the GPIB
or RS- 232 readback functions are within specifications. Note
that the readback values over the remote interface should be
identical to those displayed on the front panel.
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 and
enable the outputs by sending the commands:
VOLT:RANG P30V
OUTP ON
3 Program the output voltage to zero volt and current to
full rated value (4.0 A) by sending the commands:
VOLT 0
CURR 4
NOTE
You should program the power supply over the remote interface for this
test to avoid round-off errors.
