Self Calibration
The self calibration routine helps optimize the oscilloscope signal path for maximum
measurement accuracy. You can run the routine at any time but should always run it if
the ambient temperature changes by 5℃ or more. For a more accurate calibration,
please power on the oscilloscope and wait for 20 minutes until it has adequately
warmed up.
To compensate the signal path, disconnect any probes or cables from the front-panel
input connectors. Then, push the [Utility] button, select Calibrate option and follow the
directions on the screen.
