5.4.6.Encoder Unit (Encoder register only)
Each encoder embeds its unit in an internal parameter and the RTM Elster AMCO reads out this information
after encoder model detection. It stores the unit inside a read only parameter.
The unit parameter contains two important information that are the position of the decimal point and the unit.
ATTENTION:
the unit value will only be given for informative purpose. RTM Elster AMCO does not convert the current
unit to a standard GALLON unit and all operations are processed without taking into account the unit and
the decimal point position, it is up to the user software to convert the information in desired unit.

Encoder Unit reading response
The MSByte indicates the unit.
The LSByte indicates the number of digits before the decimal point.
Default value is assigned to 0xFFFF.
