The following graphs show the relationship between the voltage applied at the field
terminals and the data values for the module.

The following equation can be used to calculate counts values:
Counts = (Voltage In) x (3200)
The count value is returned as a multiple of 8. A voltage that would return a count value
(using the above equation) which is not a multiple of 8 will return the next highest multiple
of 8.
