To perform hardware self test
Pressing [Utility] > Service > Hardware Self Test performs a series of internal
procedures to verify that the oscilloscope is operating properly.
It is recommended you run Hardware 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 Hardware Self Test does not guarantee 100% of the
oscilloscope's functionality. Hardware Self Test is designed to provide an
80% confidence level that the oscilloscope is operating properly.
