Measures
The following parameters: sensor primary measure, final measure, min. and max.
of the final measure and the values of the analogue outputs are transmitted in the
form of a module and a unit associated with a position of the decimal point.
Eg.:

point / unit
Coding of the integer decimal point / unit
H L
Dec.point unit: code of correspondance in the list hereunder
Value of the quartet: quartet haut de l’octet H
0: no decimal
16: 1 decimal
32: 2 decimals
48: 3 decimals nombre de décimales
Eg.: 12 289 = 48 X 256 + 1
The integer encodes the unit V with 3 decimals
Hence the measure read is 10.094 V
