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.

1All segments of the display including all annunciators will turn on for about one second.

To review the annunciators, hold down Display Limit key as you turn on the power supply.

2The GPIB address or RS-232 message will then be displayed for about one second.

ADDR 05 (or RS-232)

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" in chapter 3 starting on page 56 if you need to change the remote interface configuration.

3The “15V”, “OVP”, “OCP” and “OFF” annunciators are on. All others are off.

The power supply will go into the power-on / reset state; the output is disabled (the OFF annunciator turns on); the 15V/7A range is selected (the 15V annunciator turns on); and the knob is selected for voltage control. Notice that the OVP and OCP annunciator also turn on.

4 Enable the outputs.

 

 

Press the

Output On/Off

key to enable the output. The OFF annunciator turns

 

off and the 15V, OVP, OCP, and CV annunciators are lit. The blinking digit can

 

be adjusted by turning the knob. Notice that the display is in the meter mode.

 

‘‘Meter mode’’ means that the display shows the actual output voltage and

 

current.

annunciator will turn on. See "Error Messages" for more information
