Perform Self Cal
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 performing a
self-calibration.
Do the following steps to do self-calibration:
1. Disconnect all the input channels.
2. Press the Utility button on the front panel，and then press the Do Self Cal
softkey, and the oscilloscope will pop-out the message box shown as below:
Figure 109 Do Self Cal
3. Press the Single button on the front panel to perform the self-calibration
program. During the calibration, most of the keys are disabled.
4. When the self-calibration program is finished, it will pop-out the message
“press 'Run/Stop' key to exit”. Press the Run/Stop button on the front panel
to exit the calibration interface.
