Self-calibration
The self-calibration routine optimizes performance of the oscilloscope and helps
maintaining measurement accuracy. You can perform self-calibration at any time, but
it is especially recommended when the temperature changes up to or more than 5 ℃.
Make sure that the oscilloscope has been warmed up or operated for more than 30
minutes before performing 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.
