2D IMAGES
When the 2D images check is executed, the 2D image obtained by the sensor is displayed as shown below.
There are default displays of line map (yellow line), first, peakseg, and last. When it is clicked on the 2D image display area, the display of line map,
etc, will disappear.
LED OFF
When LED OFF is checked, the infrared LED is turned OFF, and the sensor waveform becomes as shown in the figure below.

When Sensor adjustment tool is started, it is automatically displayed only once.
Though there are tabs of [Common], [Captured], [Scope adjustment], [Touch sensitivity], [Lens correction value], [therm], and [offset correction]., only
[Common], [Captured], and [Scope adjustment] are used at the current stage.
When replacing the PWB, be sure to execute the initial adjustment.
