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 5v or more. For accurate calibra-
tion, power on the oscilloscope and wait twenty minutes to ensure it is warmed up. To
compensate the signal path, disconnect any probes or cables from the input connectors.
Then, access the "Utility -> Calibration" option and follow the directions on the screen.
The self calibration routine takes about several minutes.
