In order to achieve optimal results, the measuring chain must be individually
configured and matched.

RESET/MEASURE
With an input voltage at PIN 3 (RESET/MEASURE) of 0 ... 5 V, the charge
amplifier is in the measurement mode MEASURE. If a voltage of 12 ... 30 V is
applied to PIN 3 (RESET/MEASURE), the charge amplifier switches to
RESET.
NOTE
The circuit logic of the RESET/MEASURE (level) function can be inverted
(version for high or low signal).
Setting RESET will set the amplifier output signal to zero. This can be done
with any applied force. The advantage of the Reset function is that you can
compensate initial loads and drift factors. A measurement can also be started
at a high force level.
