register addresses are indexed from zero – register 0x31 is physically sent as value
0x30, 0x32 as 0x31 (zero based addressing).
Note: In case there is a need for reading of measured values from the device with higher resolution
than one decimal, measured values in device are stored also in „Float“ format, which is not directly
compatible with IEEE754.
