Systematic errors, such as those caused by an unsuitable probe mounting, for
example, can be compensated through fine calibration.
Example: A probe provides measurements that cover a temperature range from
200 to 300 °C. It has been installed in a tunnel oven so unfavorably as to always
indicate 10°C less than the temperature of the charge. The incorrect measurement
can be corrected through fine calibration.
Actual start value : 200°C
Target start value : 210°C
Actual end value : 300°C
Target end value : 310°C

If the selected input or
signal is activated, the
display is switched off. The
parameter can only be
entered if the parameter
Switch-off event is set to
"Control signal".
A calibration (adjustment)
of the analog
measurements can be
activated here. The
adjustment is carried out
using a linear equation.
