7.9 Low‐pass filter
In some cases, it is necessary to filter the measurement
signal with a low pass, in order to eliminate interfering
noise components, for example. An internal low‐pass
filter can be connected in the CMD. The values can be
set anywhere between 1 Hz and 30 kHz.
7.10 High‐pass filter
The charge amplifier has an internally selectable
high‐pass filter (0.15 Hz and 1.5 Hz). This allows
lower‐frequency interference (drift) to be eliminated, if it
is not possible to reset the charge amplifier, for example.

7.11 Peak value memory

The analog min./max., peak and peak‐to‐peak values
can be stored in the charge amplifier and output via the
software or the analog output. Peak values can be
cleared via the digital input (DIGITAL I/O plug, pin 4) or
the software.

7.12 SensorTeach

SensorTeach is an additional function for automatically
scaling the charge amplifier using calibrated sensors.
The calibration values (sensor sensitivity) can be found in
the sensor's calibration certificate and transferred to the
amplifier using CMD Assistant.
During auto‐scaling, the amplification is set so that the
applied loads correspond to an output signal of 10 V
