Power-on Checkout
The power-on test includes an automatic self-test that checks the internal
microprocessors and allows the user visually to check the display. You will
observe the following sequence on the display after pressing the front panel
power switch to on.
1 The front-panel display will light up briefly while the instrument performs
its power-on self-test.
To review the power-on display with all annunciators turned on, hold down
key as you turn on the power supply.
2 The GPIB address or RS-232 is also displayed for about one second.
The GPIB address is set to “5” when the power supply is shipped from the
factory for remote interface configuration. If this is not the first time the power
supply is turned on, a different interface (RS-232) or a different GPIB address
may appear. See “Remote Interface Configuration” on page 79 if you need to
change the remote interface configuration.
