any measurement errors. See item Zero Correction in the chapter CONFIGURATION of this manual.

The user must choose the most suitable sensor and range to the process. The chosen range must not exceed the maximum range of

measurement defined for the sensor and should not be smaller than the minimum range for the same sensor.

It is important to note that the transmitter accuracy is based on the maximum range of the sensor used, even when a narrower

range is programmed. Example:



The Pt100 sensor in the range 0 to 100 °C and accuracy of 0.12 %, the maximum error will be 1.02 °C (0.12 % de 850 °C).



The Pt100 sensor in the range 500 to 600 °C and accuracy of 0.19 %, the maximum error will be 1.61 °C (0.19 % of the 850 °C).

Note

: When measurements are made at the transmitter, see if the Pt100 excitation current required by the calibrator is compatible with the

Pt100 excitation current used in the transmitter: 0.8 mA
