Explanation:
•
*
depends on device setting (by User’s software)
•
Int*10 register is in format integer*10
•
R register is designed only for reading
•
W*
register is designed for writing, for details see file “

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.
