Voltage Programming and Readback Accuracy

Test category = performance, calibration

This test verifies that the voltage programming and measurement functions are within specifications.

1Turn off the power supply and connect a DVM directly across the +S and -S terminals as shown in figure A. Do not connect a load.

2Turn on the power supply and program the output voltage to zero and the output current to its maximum programmable value (Imax) with the load off. The CV annunciator should be on and the output current reading should be approximately zero.

3Record the output voltage readings on the digital voltmeter (DVM) and the front panel display. The readings should be within the limits specified in the test record card for the appropriate model under Voltage Programming and Readback @ 0 V.

4Program the output voltage to its full-scale rating.

5Record the output voltage readings on the DVM and the front panel display. The readings should be within the limits specified in the test record card for the appropriate model under Voltage Programming and Readback @ Full Scale.

CV Load Effect

Test category = performance

This test measures the change in output voltage resulting from a change in output current from full load to no load.

1Turn off the power supply and connect a DVM and an electronic load as shown in figure A.

2Turn on the power supply and program the output current to its maximum programmable value (Imax) and the output voltage to its full-scale value.

3Set the electronic load for the output’s full-scale current. The CV annunciator on the front panel must be on. If it is not, adjust the load so that the output current drops slightly.

4Record the output voltage reading from the DVM.

5Open the load and record the voltage reading from the DVM again. The difference between the DVM readings in steps 4 and 5 is the load effect, which should not exceed the value listed in the test record card for the appropriate model under CV Load Effect.
