A displayed value of
indicates no light received or a loss of signal.
In Window Set teach mode, the value 100 represents the taught signal strength. The displayed value is the percentage of
the received light divided by the taught signal strength. The output switches at displayed values above and below 100 as
determined by the user-selected window offset percentage.
