Power-on checkout
The power- on test includes an automatic self- test that
checks the internal microprocessors and allows the user
visually check the display. You will observe the following
sequence on the display after pressing the front panel power
switch to on.
1 All segments of the display including all annunciators will
turn on for about one second.
To review the annunciators, hold down as
you turn on the power supply.
2 The GPIB address or RS- 232 message will then be displayed
for about one second.
ADDR 5 (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.
3 The 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 15 V/7 A 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 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.
Refer to Chapter 3, “Remote Interface Reference” if you need to change
the remote interface configuration.
