Introduction

Successful tests in this chapter provide a high degree of confidence that the ac source is operating properly. For verification tests, see appendix B. Complete performance tests are given in the Service Guide.

NOTE: This chapter provides a preliminary introduction to the ac source front panel. See Chapter 4 for more details.

WARNING: LETHAL VOLTAGES. Ac sources can supply 425 V peak at their output. DEATH on contact may result if the output terminals or circuits connected to the output are touched when power is applied.

1.If you have not already done so, connect the power cord to the ac source and plug it in.

2.Turn the front panel power switch to ON (1).

3.The ac source undergoes a self-test when you turn it on. The following items appear on the display:

a.A brief pattern that lights all display segments, followed by the model number and the software revision number.

b.The display then goes into the meter mode with the Dis annunciator on, and all others off. "Meter mode" means that the VOLTS digits indicate the output voltage and the FREQ digits indicate the output frequency. The voltage will be at or near zero and the frequency will be at 60 Hertz.

Note: If the ac source detects an error during self-test, the Err anunciator on the display will be lit. Pressing the Shift and Error keys will show the error number. Go to "In Case of Trouble" at the end of this chapter.

4.Check that the ac source fan is on. You should be able to hear the fan and feel the air coming from the unit.

5.Press Output on/off once. The Dis annunciator will go off and the CV annunciator will go on.

6.Turn the unit off.
