15.1 Fine adjustment
You can use customer-specific fine adjustment to correct the measured values of the analog
input. In contrast to offsetting, which is used to specify a constant correction value for the entire
characteristic line, fine adjustment can also be used to change the slope of the characteristic
line.

Parameters
Example
The temperature inside a furnace is measured with an RTD temperature probe and displayed.
Due to the temperature drift of the sensor, the true temperature (reference measurement) de-
viates from the displayed value. The amount of deviation is different at the upper and lower
measuring points, meaning that measured value offset is not suitable.
Actual zero point: 15 °C (lower displayed value)
Set zero point: 20 °C (lower reference value)
Actual end value: 70 °C (upper displayed value)
Set end value: 80 °C (upper reference value)
Parameter Selection/settings Description
