To run the self calibration

Let the Oscilloscope Warm Up Before Adjusting
CAUTION
Warm up the oscilloscope for 30 minutes before starting calibration procedure.
Failure to allow warm up may result in inaccurate calibration.
The self calibration uses signals generated in the oscilloscope to calibrate channel
sensitivity, offsets, and trigger parameters. You should run the self calibration
• yearly, or according to your periodic needs,
• when you replace the acquisition assembly or acquisition hybrids,
• when you replace the hard drive or any other assembly,
• when the oscilloscope's operating temperature (after the 30-minute warm-up

Let the oscilloscope warm up before running the self calibration.
The self calibration should only be done after the oscilloscope has run for 30
minutes at ambient temperature with the cover installed. Calibration of an
oscilloscope that has not warmed up may result in an inaccurate calibration.
