Object Detection SET
The distance to the target is sampled; the sensor places the cutoff point at
approximately 105 percent of the distance to the target. In RUN mode, objects located
between the minimum range and the cutoff are sensed; anything beyond the cutoff
(e.g., other objects or background surfaces) is ignored.
Minimum range varies, depending on the cutoff distance and reflectivity
(see Figure 11).

Manual Adjust
• Click the push buttons (“+” or “-”) to adjust the cutoff by approximately 2 percent.
- To suppress background more, click Background button.
- To increase object detection, click Object button.
• The display will momentarily blink to acknowledge cutoff movement.
• If the cutoff is at an extreme, the “far” (7th and 8th) or “near” (1st and 2nd)
bargraph segments will flash simultaneously to indicate that the cutoff did not
adjust.
* Segments 7 and 8 simultaneously flashing: Indiscernible target; sensor defaults to maximum cutoff.
Segments 1 and 2 simultaneously flashing: Cutoff set is nearer than minimum cutoff; sensor defaults to minimum cutoff.
