6.2.2 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 gradient of the characteristic
line.

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 start value: 15 °C (displayed value)
Target start value: 20 °C (reference measurement)
Actual end value: 70°C (displayed value)
Target end value: 80 °C (reference measurement)
