This tab is used to set when the sensor unit is delivered.

Lens correction value tab settings are made when delivering the sensor

unit, and basically cannot be adjusted in the market.

For setting with [therm] tab, refer to the temperature compensation set-
ting which was automatically set in the sensor waveform dialogue. In

addition, the temperature compensation setting can be disabled.

Interruption mode detection level. 

When this value is increased, detection 
level of the interruption mode is 

decreased.

When “(2) SENSOR CHECK AND ADJUSTMENT - 3” is selected, the X-Y plot dialogue is displayed as shown below. The drop-down menu at the
left upper of the dialogue allows selection of [Double-size scale], [Normal-size scale], [Reduction double-size scale], and [Reduction normal-size

scale].
3Refer to page 4 - 41  "(2) SENSOR CHECK AND ADJUSTMENT".

When each item is selected, the display is as shown below to allow checking the coordinates of interruption detection and its size.

Since the effective area of the PN-L802B is in the double-size scale display, there is no need to use the normal-size scale display which displays a
wider area than that.
