Self Tests
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 internal diagnostics to verify that the instrument passes the
internal circuit tests, and calibration routines to check and adjust the instrument
internal calibration constants.
This procedure uses internal routines to verify that the instrument is operating
correctly. No test equipment or hookups are required.
The instrument automatically performs the internal diagnostics when powered
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
diagnostics is that the menu method performs a more detailed memory check.
Equipment
required
None
Prerequisites Power on the instrument and allow a twentyĆminute warmĆup period
before doing this procedure.
Confirm that there is no output being performed by verifying that the RUN LED
is not on. If the LED is on, push the RUN button to turn it off.
Do the following to verify that the instrument passes the internal circuit tests:
Push UTILITY (front-panel)!Diag (bottom)!Diagnostic All (side).
The diagnostic menu is displayed and all tests are selected. Refer to
Figure 4–1. If All is not displayed, select All using the general purpose
knob.
The list displayed on the screen shows the test items and results in the calibration
and diagnostics previously performed. Select all of the test items shown on the
screen or use the general purpose knob to select a single test item that you want to
run. The results of the diagnostics are shown as error codes. Pass means that the test
results occurred without error. If an error is detected, an error code is displayed.
You can also specify how many times to perform the diagnostic tests. Push the
Cycle side button and then turn the general purpose knob to select the cycle from
1, 3, 10, 100 or Infinite. When you select Infinite, the tests are repeatedly
performed and are not be terminated until you push the Abort Diagnostic side
button.
