Line Brightness Display
This display allows checking the line beam image and the brightness information for each line
(line brightness).
• At setting: It is possible to check whether sensitivity is appropriate.
• During measurement: It helps analyzing factors when an error occurs.
Line Brightness (Brightness Distribution) (Yellow)
The line brightness graph at the cursor position is displayed.
It is possible to know at a glance whether or not, for example,
the light density is insufficient, or is at the saturation level.
This indicates the brightness of each line; move the cursor to
check brightness of other lines.

The shape of workpieces and
the way they are detected
can be checked.
LV: Displays current sensitivity level. (1 to 31)
The value increases with increase in darkness of
the workpiece, while it decreases with increase
[ ] in brightness of the workpiece.

PEAK: Displays current received level.
Use this value as reference when setting
the sensitivity level.
