Scaling for Bipolar Outputs
The following graph illustrates the relationship between the output voltage
measured at the field terminals and the data that is output by the module, when
outputs are set up for the bipolar range.

Voltage can be calculated using the following equation:
Vout = ( (analog counts x 20.48) / 65536 )
The count value must be a multiple of 4. If the module receives a count value
that is not a multiple of 4, it rounds the value down to the closest multiple of 4.
For example:

16028 5.00875V
