System Settings (SYS)
The APC (Auto Power Control) function automatically adjusts the light emission at a
constant level.
This function reduces variation in the received light intensity due to changes in
ambient temperature.
• The APC function monitors and adjusts the LED light emission.
Therefore, variation in the received light intensity due to contami-
nation or characteristic changes of fiber unit cannot be reduced.
When high-precision detection is necessary, also apply the DATUM
function and percentage calibration using external input.
DATUM function "Detection Mode" (page 4-8)
Percentage Calibration "Percentage calibration" (page 4-5)
• If the unit is used for an extend period with the APC function
turned ON, heavier load is imposed on the light emitting LED than
when the unit is used with the APC function turned OFF. Normally,
use the unit with APC turned OFF.
