Self-calibration

The self-calibration program can make the oscilloscope quickly reach the optimum
working state to acquire measurement values as accurate as possible. You can
configure the instrument to perform the self-calibration program at any time; it is
especially recommended when the temperature change is up to or more than 5℃.
Make sure that the oscilloscope has been warmed up or operated for more than 30
minutes before performing 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 to open the self-calibration menu and the
self-calibration interface.
Press Start and the oscilloscope will start to execute the self-calibration program.
Press Exit at any time; the oscilloscope will stop the self-calibration operation and
exit the self-calibration menu.
Note:
During the self-calibration process, the instrument will check the cable

connection status. If cable connection error occurs, "Selfcal connection error!"
will be displayed; please check the cable connection and restart the
self-calibration operation.
Most of the keys are disabled during the self-calibration process.
