Hello Dear , I found that there is +1 offset
as my adress resgister is 00 for voltage for example correct floating value is 1
as I add +1 for all register values its OK
PS : before converting HEX to DEC
thanks a lot

There is a setting in the driver for one based/zero based, go to edit settings and click show advanced.

Therefore your registers in your address can match the documentation.
