4-29 - Digital Fiber Sensor FS-N10 Series User's Manual -
Operating principles of the preset function
(Current received light intensity is 3300 in this example.)
Preset input is used to register the
light intensity as "
100.0 ".
The actual received light intensity (3300)
is set to "110%" and all actual received
light intensities exceeding "100%" are
displayed as "
100.0 ".
When light intensity falls below "100%", a
value lower than "
100.0 " is displayed.
(The percentage value "110%" (i.e., the
saturation level) at the time of registration
can be any value between 100 and
200%.)
"Preset Saturation Function" (page 4-
28)
If the displayed light intensity falls below
"
100.0 ", the preset input can be per-
formed again to restore stable detection.
If light intensity is not displayed as "
100.0 "
after preset input, the sensor amplifier is not
in stable detection condition.
Even when the maximum sensitivity preset function or full auto preset func-
tion is used, the preset saturation level setting function operates based on
the "
100.0 " point.
