Measuring quality:
This value indicates the significance of the precipitation classification (parameter 11,12 and
13). The sensor analyse for this value the quantity of the particles and the measured
ambient temperature. It should be considered that other factors (e.g. wind speed, dense fog)
can decrease the measuring quality provided by the instrument.

Internal data (raw values).

The particle spectrum are raw data. Obvious illogical measurements (e.g. particle no
hydrometeor, snow-particle when temperature is greater than 8°C) should if necessary
removed.

Calculation checksum:
The two’s complement of the sum of all characters (alpha-numeric and control character like
STX / ETX / CR / LF), but not the checksum, is calculated. Given out is from the least
significant byte (LSB) the high- and low-nibble (half-byte) in two characters in hexadecimal
ASCII-code.
