Function 2......Sets the sensitivity adjustment method to [Auto] and changes the sensitivity level
of the sensor, turns off the laser, or changes gradations.

Input
• Specify values in the range between 0 and 31 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 the 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
circumstances.)
The total delay time for turning the laser off can be shortened with input from the terminal block. If
the laser must be turned off instantaneously, use the LD-OFF input terminal block.
