Fixed channel allocations
Due to the internal wiring of the logger, current loops can only be connected to the
channels 2 and 4.
The internal pressure sensors P1 and P2 are always linked to channel 1 and 3. If the
logger is equipped with one or two internal pressure sensors, the respective channels
are in use and must not be connected to external sensors.
Corresponding to these conventions, the following channel allocations apply:
Channel 1 Channel 2 Channel 3 Channel 4
