Sensor error adjustment (sensor trimming)
Sensor trimming is used to adapt the actual sensor signal to the linearization of the
selected sensor type stored in the transmitter. Compared to sensor transmitter matching,
sensor trimming only takes place at the start and end value and does not achieve the same
level of accuracy.
Sensor trimming does not adapt the measuring range. It is used to adapt the sensor
signal to the linearization stored in the transmitter.
Procedure
1. Start
ß
2. Set the Sensor trimming parameter to the Customer-specific setting.
ß
3. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature. A
temperature which is close to the set start of the measuring range is recommended.
ß
4. Enter the reference temperature for the value at the start of the measuring range for the Sensor trimming
lower value parameter. Based on the difference between the specified reference temperature and the
temperature actually measured at the input, the transmitter internally calculates a correction factor which is
now used to linearize the input signal.
ß
5. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature
close to the set end of the measuring range.
ß
6. Enter the reference temperature for the value at the end of the measuring range for the Sensor trimming
upper value parameter.
ß
7. End

Description Use this function to select the linearization method to be used for the connected sensor.
The original linearization can be restored by resetting this parameter to the Factory
setting option.
