Introduction
Successful tests in this chapter provide a high degree of confidence that the Agilent SAS is operating properly. For
verification tests, see appendix B under Verification. Do not apply ac power to the Agilent SAS until told to do so.
Note This chapter provides a preliminary introduction to the Agilent SAS front panel. See chapter 5 - Front
Panel Operation for more details. During this procedure, the Agilent SAS is operating in Fixed mode.
Preliminary Checkout
1. Make certain that the front panel switch is off.
2. Examine the Line Fuse Rating label on the rear panel.
a. Verify that the line voltage rating agrees with your ac line. If it does not, see chapter 2 under AC Line Voltage
Conversion.
b. Use a screwdriver to remove the line fuse from the fuseholder. Verify that the fuse is as specified on the label.
Replace the fuse.
3. Check that the SENSE switch is set to Local.
4. Make sure that there is no load connected to the output terminals or bus bars.

LCD:
a.
∗ ∗ ∗ ∗ ∗ a brief star-burst pattern which lights all the LCDs, followed by
b. A D D R 5 the GPIB address (factory default is 5).
4. 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 AMPS digits indicate the output current. These values will be at or
near zero.
5. Verify that the Agilent SAS fan is on by placing your hand near the rear grill to feel the air flow. You may also be able to
hear the fan operating.
6. Press
once. The Dis annunciator will go off and the CV annunciator will go on .
Note If the Agilent SAS detects an error during self-test, the display will show an error message. Go to “In Case
