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 User trim settings setting.

ß

3. Using a water/oil bath or a furnace, 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 predefined 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 or furnace, 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 trim
settings option.

Description

Lower point for linear characteristic calibration (this affects offset and slope).
