9.1 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 con-
stant correction value for the entire characteristic line, fine adjustment can also
be used to change the gradient of the characteristic line.
Overview
Parameter
Example The temperature inside a furnace is measured with an RTD temperature probe
and displayed. Due to the temperature drift of the probe, the true temperature
(reference measurement) deviates 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)
