The coefficients for a standard sensor are specified in IEC 751. If no standard sensor is available or if greater accuracy is required, the coefficients for each sensor can be determined specifically with the aid of sensor calibration. Sensor-transmitter-matching using the method explained above significantly improves the temperature measurement accuracy of the entire system. This is because the transmitter uses the specific data pertaining to the connected sensor to calculate the measured temperature, instead of using the standardized sensor curve data. 1-point adjustment (offset) Shifts the sensor value Current output adjustment Correction of the 4 and/or 20 mA current output value.
