To avoid electric shock, always keep your finger behind the safety
guard ring of the probe during the operation.

How to Implement Self-calibration
The self-calibration application can make the oscilloscope reach the optimum
condition rapidly to obtain the most accurate measurement value. You can
carry out this application program at any time. This program must be executed
whenever the change of ambient temperature is 5℃ or over.
Before performing a self-calibration, disconnect all probes or wires from the
input connector. Click the
icon, select the Utility softkey, select Function
in the bottom menu, select Adjust in the left menu, select Self Cal in the
bottom menu; run the program after everything is ready.
