Setting the Threshold (Teach Function)
Mechanism of the Threshold Setting
The received light amounts obtained during the two actions of the teaching are set as the upper and lower
thresholds.
Example) When the received light amounts during the two actions of the teaching are 2000 and 1000
The threshold is set with an upper limit of 2000 and a lower limit of 1000, so detection occurs when
the received light amount is in the range of 1000 to 2000.
