NOTE: The dc source must pass turn-on selftest before you can proceed with the verification tests.

Voltage Programming and Measurement Accuracy

This test verifies the voltage programming, HP-IB measurement, and front panel meter functions. Values read back over the HP-IB should be the same as those displayed on the front panel. Measure the dc output voltage at the output terminals. Make sure the output mode switch is set to Normal and the sense terminals are directly jumpered to the output terminals.

Action

Normal Result

1.Turn off the dc source and connect a DMM to the output terminals.

2.Turn on the dc source with no load on the output. Set the output voltage to 0 V and the output current to full scale (see table B-2). Press Output On/Off to enable the output.

Output voltage near 0 V. Output current near 0 A.
