The Self Tests use internal routines to confirm basic functionality and proper
adjustment. No test equipment is required to do these test procedures.
The Functional Tests utilize the probe-compensation output at the front panel as
a test-signal source for further verifying that the oscilloscope functions properly.
A probe is required to do these test procedures.
This procedure uses internal routines to verify that the oscilloscope functions and
was adjusted properly. No test equipment or hookups are required.
Equipment None

status will appear on the screen.
d. Verify that no failures are found and reported on-screen. If any failures
occur do step 1a, then press the main menu button Error Log for details.
