The graphs below show the relationship between the output voltage measured at the field
terminals and the data that is output by the module.

8 counts =
2.5mV
Voltage can be calculated using the following equation:
Vout = ( (analog counts x 10.25) / 32768 )
The count value must be a multiple of 8. If the module receives a count value that is not a
multiple of 8, it rounds the value down to the closest multiple of 8. For example:
Count Voltage
16024 5.0125V
16030 5.0125V
16032 5.0150V
