Current Programming and Readback Accuracy

Test category = performance, calibration

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

1Turn off the power supply and connect the current shunt directly across the output. Connect the DVM across the current shunt.

2Turn on the power supply and program the output voltage to its full-scale value and the output current to zero. The CC annunciator should be on and the output voltage reading should be approximately zero.

3Divide the voltage drop (DVM reading) across the current shunt by its resistance to convert to amps and record this value (Iout). Also record the current reading on the front panel display. The readings should be within the limits specified in the test record card for the appropriate model under Current Programming and Readback @ 0 A.

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

5Divide the voltage drop (DVM reading) across the current shunt by its resistance to convert to amps and record this value (Iout). Also record the current reading on the front panel display. The readings should be within the limits specified in the test record card for the appropriate model under Current Programming and Readback @ Full Scale.

CC Load Effect

Test category = performance

This test measures the change in output current resulting from a change in output voltage from full scale to short circuit.

1Turn off the power supply and connect the current shunt, DVM, and electronic load as shown in figure B. Connect the DVM directly across the current shunt.

2To ensure that the values read during this test are not the instantaneous measurement of the AC peaks of the output current ripple, several DC measurements should be made and averaged. If you are using an Agilent 3458A, you can set up the voltmeter to do this automatically. From the instrument’s front panel, program 100 power line cycles per measurement. Press NPLC 100 ENTER.

3Turn on the power supply and program the output current to its full-scale value and the output voltage to its maximum programmable value (Vmax).
