Self Tests
The Self Tests use internal routines to confirm basic functionality and proper
adjustment. No test equipment is required to do these test procedures.
The self tests include these internal routines:
H Diagnostics
This self-test procedure uses internal routines to verify that the instrument
functions, and passes the internal circuit tests.
H Calibration
The second procedure checks the instrument internal calibration constants
and changes them if needed.
This procedure uses internal routines to verify that the instrument functions and
was adjusted properly. No test equipment or hookups are required.
The instrument automatically performs the internal diagnostics at power-on; you
can also run the internal diagnostics using the menu selections described in this
procedure. The difference between these two methods of initiating the diagnos-
tics is that the menu method does more detailed memory checking than the
power-on method.
Equipment
required
None
Prerequisites Power on the instrument and allow a twentyĆminute warmup period
before doing this procedure.
1. Confirm that no output is performed: Confirm that the RUN LED does not
light. If not, push the RUN button so that the RUN LED goes off.
2. Verify that internal diagnostics pass: Do the following substeps to verify
passing of internal diagnostics.
a. Display the diagnostics menu and select all tests:
H Push UTILITY (front panel)!Diag (bottom)!Diagnostic All
(side).
H If All is not displayed, select All using the general purpose knob.
The screen as shown in Figure 4–1 appears.
