7.3.2 Amplification
The amplification of the receiver signal can be set in the
range of 10..256 (1000).
10: Lowest amplification: Smallest signal, less noise, low
range
256: Highest amplification: Largest signal, more noise, high
range
1000: additional computational amplification, more noise,
highest range (only in "Advanced Amplification Mode")

7.2 Signal Acquisition
7.2.1 Description
Sensor Principle
The sensor performs measurement value acquisition as a
continuous signal that is evaluated for switching signal
generation.
The following teach methods are available: Single value
teach and dynamic teach.
7.2.2 Teach Methods
For a successful teach-in as well to directly set a setpoint,
the following conditions must be met:
The setpoint that is to be taught must be in the validity
range of the measurement value signal.
An active teach process is indicated by illumination of the
red LED. If the red LED flashes, the currently pending
measurement value is outside of the validity range.
Single Value Teach
With single value teach, the switching point (setpoint) is
defined via a teach point. Moreover, this is a static process,
i.e., the measurement value is constant during the teach
phase.
Dynamic Teach
With this process, no static teach points are recorded,
unlike with the previous methods; rather, multiple measure-
ment values are recorded over a defined period of time.
For this purpose, the minimum and maximum values are
determined. The average value of these two extrema is
used to form the new switching point (setpoint). The
maximum acquisition time is 60 seconds, then the
teaching process is aborted.
