Function 2......Sets the sensitivity adjustment method to [Multi] and changes the sensitivity level
of the sensor, turns off the laser, or changes gradations.
SENSM <Priority item> <Sensitivity levelLower limit> <Sensitivity levelUpper limit>
Input
<Gradations>
• Specify the item that has priority at the time of multiple sensitivity adjustment as the
priority item.
Priority item
0
1
• Specify values in the range from 0 to 31 (0 to 25 if the sampling period has priority)
for the sensitivity level lower limit and sensitivity level upper limit.
The optimum sensitivity level is set within the range from the lower limit to upper
limit.Set the values so that the lower limit is equal to or less than the upper limit.
If the same value is set for the lower limit and upper limit, the sensitivity will be fixed
at that level.
If both the lower limit and upper limit are set to 0, the laser will be turned off.
(However, a measurement error will be generated.)
• Specify a value in the range between 120 and 220 for gradations as the target value
of sensor sensitivity adjustment.
(Specify 170 under normal circumstances.)
The total delay time for turning the laser off can be shortened more with input from the terminal
block. If the laser must be turned off instantaneously, use the LD-OFF input terminal.

Perform the following procedure in order to set the optimum sensitivity for the
workpiece to be measured.
Example:
SENSM 1
Delimiter
Input
:17 25
Delimiter
Output
The optimum sensitivity is in the range of 17 to 25.
SENSM 1 17 25 170
Input
OK
Delimiter
Output
The sensitivity level is automatically adjusted in the range between 17 to 25 with a
target light reception level of 170 while giving priority to the sampling period.
