Accuracy of outputs
The output accuracy must be factored into the measured error if analog outputs are
used, but can be ignored for fieldbus outputs (e.g. Modbus RS485, EtherNet/IP).
The outputs have the following base accuracy specifications.

o.f.s. = of full scale value
When there is a difference between the temperature for zero point adjustment and the
process temperature, the additional measured error of the sensor is typically ±0.0002 %
o.f.s./°C (±0.0001 % o. f.s./°F).
