Auto adjust level
If the received light drops suddenly within the set percentage (%), the sensor will judge that
there is contamination and not a target, and auto adjust will be executed.
Conversely, if the received light drops more than the set percentage, the sensor will judge
that a target has entered the area, and auto adjust will not be executed.
If the adjust function is executed when the light is less than a set percentage of the
reference received light amount, the check is output.
This notifies an external source that there is dirt or oil on the measurement section and
compensation cannot be completed.
Light level value setting screen for check output function
When check output function ON is selected, the screen for setting the light in respect to the
reference light will open. (When OFF (disabled) is set, this screen is skipped.)
Press the  /  button on the light level value setting screen to adjust the light level.
