Selecting the Sensor data
the measuring-gas input starts flowing through the CH
from 0 to 1023 dig.
The theoretical display can hence be calculated as follows at a defined calibration gas concentration.

The above equation does not have to be fulfilled exactly. The equation neglects, for example, the fact that the signal should feature a
slight offset with zero gas (living zero point). The actual sensor signals should be within the limits shown below.

In order to determine the zero point of the sensor, the biogas hose must be disconnected from the detonation protection

unit, so that ambient air is drawn in through the measuring-gas input.
A calibration gas / biogas with the following composition was used as a basis for the sensor signals indicated:

The Sensor data menu serves the functional checking of the sensors and thereby supports remote
diagnosis by the manufacturer.
The current sensor signals and the signals of the last three measurements (HISTORY) can be
