User Cal Self Test
User Cal
Pressing the User Cal softkey performs an internal self-alignment routine to
optimize the signal path in the oscilloscope. The routine uses internally
generated signals to optimize circuits that affect channel sensitivity, offset, and
trigger parameters. Disconnect all inputs and allow the oscilloscope to warm up
before performing this procedure.
User Cal should be performed at least once a year, any time the ambient
temperature of the oscilloscope has changed more than 10 °C since the last User
Cal, or after any repair.
Performing User Cal will not invalidate your Certificate of Calibration.
Successful completion of User Cal does not certify this oscilloscope with a
National Institute of Standards and Technology (NIST) calibration.
