Basic Operations
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.
How to change the cursor position p.144
Common Display
Items commonly displayed in both the profile and line brightness displays are explained below.
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.

Line beam image
The shape of workpieces and
the way they are detected
can be checked.

Output number
(OUT 0 to OUT 7)
The output number
for the currently
displayed
measurement result
is displayed.
Measurement value
The measurement
value is displayed
in green if the judgment
result is PASS.
It is displayed in red
if the judgment result
is HIGH, LOW,
or ERROR.
Forced-zero
Zero's OFF: Forced-zero not executed
Zero's ON: Forced-zero executed
Judgment results
HIGH : Greater than the judgment upper limit
PASS : Within the judgment limits
LOW : Less than the judgment lower limit
ERROR : Measurement error
-The workpiece is out of the measurement range
-The light density is insufficient
-Information on the measurement point cannot
be obtained, or other cases
RESET: No-measurement state
LD-OFF: LD-OFF input
PASS
mm
+005.188000
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.
120 max.: Insufficient light density
255 min.: Excessive light density
