•
Sets a threshold exactly at the presented condition
•
Threshold can be adjusted using "+" and "-" rocker button (Manual Adjust)
A single sensing condition is presented, and the sensor positions a threshold exactly at the presented condition. When a
condition lighter than the threshold is sensed, the output either turns ON or OFF, depending on the LO/DO setting.
