î Automatic Teaching
For automatic teaching, measurements are performed while the RIGHT
Key and the ENT Key are pressed at the same time. The center value
between maximum and minimum values is set as a threshold.
The threshold value is set when the keys are released.
The threshold can be set according to the sensing object.
