Self Calibration: The self calibration routine can optimize the precision of the
oscilloscope to fit the ambient temperature. To maximize the precision, you should
perform the self calibration once the ambient temperature changes by 5℃ or more.
Follow the instructions on the screen.
Tip: Press any menu button on the front panel to remove the status display and

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
