1.7 Self Calibration
The self calibration routine lets you optimize the oscilloscope signal path for maximum
measurement accuracy. You can run the routine at any time but you should always run the
routine if the ambient temperature changes by 5℃ or more. For accurate calibration,
power on the oscilloscope and wait twenty minutes to ensure it is warmed up. To

screen. The self calibration routine takes about several minutes.
