Self-calibration
The self-calibration program can quickly make the oscilloscope reach the best
working state to get the most precise measurement values. You can perform
self-calibration at any time especially when the change of the environment
temperature is up to or more than 5 ℃. Make sure that the oscilloscope has been
warmed up or operated for more than 30 minutes before the self-calibration.
The self-calibration uses the fast edge signal output from the [Trig
Out/Calibration] connector at the rear panel as the calibration signal. Please
connect this signal to the four input channels and the external trigger input channel,
and then press Utility  Self-Cal and the self-calibration interface as shown in the
figure below is displayed.
Press Start and the oscilloscope will start to execute the self-calibration program.
Press Exit to give up the self-calibration operation at any time and return to the
previous menu.
Note: most of the keys are disabled during the self-calibration.
