To run the internal self-tests
Self Test performs a series of internal procedures to verify
that the oscilloscope is operating properly.
It is recommended that you run the Self Test:
•
after experiencing abnormal operation
•
for additional information to better describe an
oscilloscope failure
•
to verify proper operation after the oscilloscope has been
repaired
Successfully passing Self Test does not guarantee 100% of
the oscilloscope’s functionality. Self Test is designed to
provide an 80% confidence level that the oscilloscope is
operating properly.
1
Press the
Utility
key, then press the
Service
softkey.
2
Begin the internal self tests by pressing the
Start Self Test
softkey.
To verify default setup
The oscilloscope is designed to turn on with the setup from
the last turn on or previous setup. However, if the Secure
Environment option is installed, the oscilloscope will always
execute a Default Setup upon power- up.
To recall the factory default setup:
1
Press the
Save/Recall
key.
2
Press the
Default Setup
softkey.
This returns the oscilloscope to its factory default settings
and places the oscilloscope in a known operating
condition. The major default settings are:
•
Horizontal
- main mode, 100 us/div scale, 0 s delay,
center time reference
