Measuring data consist of a counter, the packet length m and the measurements. The packet length m determines how many mea-
surements are transmitted. The packet length m is the number of measurements that have been queried by the electronic system
since the last time measuring data were queried, but is limited to the most recent 20 measurements. The first measurement in the
data [] package is the oldest value queried, the last one is the most recently queried value.

Scaling of measurements
BY default, 24-bit measurements are transmitted.
The following equivalences therfore apply:
0x0 = 0 % of the sensor measuring range
0xF00000 = 100 % of the sensor measuring range
If the sensor is outside the measuring range, accordingly larger
measurements are output.
