3.2.2 Introduction to the Calibration Interface
Calibration shall be performed when it is the first time to use the device.

Refer to the steps and diagram shown on the right.
3.2.3 Quick Calibration
The system directly enters the calibration interface when it is used for the first time. Alternatively, users can
