Response speed selection function
DIP switch 3
Set DIP switch 3 to select whether to output every measured value or
the average of 8 measured values (moving average).
LOW:
Outputs the value of the average of 8 measured values. Offers more
stable detection when the luster of the target varies greatly.
HIGH:
Outputs every measured value. Offers high-speed response when the
target vibrates or moves quickly.
FUNCTIONS DIP SWITCHES
Average response time LOW HIGH
LK-031/036 Approx. 4 ms Approx. 0.5 ms (no averaging)
LK-081/086/501/503 Approx. 8 ms Approx. 1.0 ms (no averaging)
Example: When LOW is set
Example: When HIGH is set
The HIGH setting is effective in detecting abrupt changes, such as height
differences.
