2.13.2 52BSelf 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.

input connectors. Then, push the UTILITY button, select the Do Self Cal option and
follow the directions on the screen.
