4.1.10 Error Correction
Performs a fine adjust of the transmitter when known inputs can be applied or when a
sensor calibration protocol is available. To open the Error Correction form (se figure 27 Error
Correction), select from the menu 'Miscellaneous-Error
Correction' or click the Error Correction icon.

4.1.10.1 Sensor Error Correction
A 2-point sensor error correction can be performed when a sensor calibration protocol is
available. The actual temperature and the observed temperature from the calibration
protocol are required. You get the best result if the two points are near the limits of the
measuring range, because this will give a higher accuracy.
4.1.10.2 System Error Correction
A 2-point system error correction can be performed when two known temperatures can
be applied to the sensor connected to the transmitter. The transmitter input value will also
have to be measured (this could be done in the Error Correction window). You get the best
result if the two points are near the limits of the measuring range, because this will give a
higher accuracy.
Note: If you want to cancel a performed sensor error correction or system error
correction, insert the value 0 into the Reference and Measurement Temperature boxes and
press OK. Then download the configuration into the transmitter.
