3. Turn-On Checkout
3.1 Preliminary Checkout
Successful tests in this chapter provide a high degree of confidence that the AC
source is operating properly. For verification tests, see section 6.2 . This chapter
provides a preliminary introduction to the AC source front panel. See chapter 6 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.
If you have not already done so, connect the power cord to the AC source and plug it
in.
•
Turn the front panel power switch to ON (1).
•
The AC source undergoes a self-test when you turn it on.
•
The following items appear on the display:
•
A brief pattern that lights all display segments, followed by the model number
and the software revision number.
•
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 annunciator
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.
•
Check that both fans are on. You should be able to hear the fans and feel
air coming from the unit.
•
Press Output on/off once. The
Dis
annunciator will go off and the
CV
annunciator will go on.
•
Turn the unit off.
