Dark SET
•
Sets a threshold a programmable % offset above the presented condition
•
Any condition lighter than the threshold condition causes the output to change state
•
Threshold can be adjusted using "+" and "-" Navigation key (Manual Adjust)
•
Recommended for applications where only one condition is known, for example a stable dark background with varying lighter
targets
•
See
Program Mode
for programming the Offset Percent setting
A single sensing condition is presented, and the sensor positions a threshold a programmable % offset above the presented condition.
When a condition lighter than the threshold is sensed, the output either turns ON or OFF, depending on the LO/DO switch setting
(see
LO/DO Switch
in
Top Panel Interface
).
