si gnalling LED.

7.5. Sensitivity mode (see f unctions 15÷18 of Tab.1 at page 14)
This function allows the sensitivity adjustment according to the
characteristics of the object to be detected.
The standard value is fixed on level 9; in presence of small objects
(comparable to the detection limit = 0.5 mm) or very transparent
objects, with the units at the maximum operating distance, we
recommend increasing the sensitivity to level 5.
In all other cases, such as when the detection or the calibration
procedure is very difficult, we recommend decreasing the sensitivity to
level 15.
The sensitivity increase is recommended only if strictly necessary, as
the increase can deteriorate the immunity characteristics and require
more frequent calibration operations.
Operating on the 5 and 9 sensitivity levels (high sensitivity) can be
accomplished only in the manual calibration mode.
