HP 3468A - Page 9

Before applying ac power to the 3468A, check the rear panel line voltage option
label to be certain the instrument is set for the nominal line voltage in your area. If
necessary, refer to the installation information in Chapter V. As you press the line
switch, carefully watch the display as the 3468A goes through a complete inter-
nal self test.
DISPLAY
RESULT
The 3468A performs a complete inter-
nal self test at power-on. Carefully
watch the display, especially the 12
annunciators along the bottom. Every
segment
in
the
display
(except
for
the
top dot in the colon) is turned on for
approximately 2 seconds. Following
this, a complete turn-on self test is
performed. The 3468A is then reset
and returns to its turn-on state. A
more
complete
description
of
the
Self
Test is found in Chapter Il, page 25.
Should any of the five elements of the
self test fail, a message will be
displayed
identifying
the
general
circuit
area where the failure occurred. This
can greatly reduce initial trouble-
shooting time.
This entire process takes only a mo-
ment to complete. At this point the
3468A is ready to use and is set to
the following state:
Function: DC Volts
Range: Autorange on
Display: 5 1/2 Digits of Resolution
Trigger: Internal Trigger
Auto-zero: On
