J SENSITIVITY SETTING—THRESHOLD SETTING AND INDICATORS
Maximum Sensitivity Setting
•
•
The threshold should be set to a level slightly higher than the Zero point when detecting objects that completely interrupt light.
Diffuse Sensor
The number of incident level indicators that are lit will depend on the location of the object. The bottom indicator of the threshold indicators
will always be lit.

RUN/ADJ Mode
The number of the incident level indicators lit depends
on the position of the target. When using the
manual-tuning function, it is possible to adjust the
threshold in six levels. The default threshold is set to 7.
