SOL3-1
2.3 Sensor calibration
The controller is designed for connection of Pt1000-sensors. The sensor values of
resistance are listed on page 46.
If the temperature values displayed by the controller do not match the real temperatures,
the measured values of the connected sensors can be adjusted. The temperature value
displayed has to be replaced by the value measured directly at the measuring point
(reference value). The adjustment has to be activated in CO5, function block F20. A
wrong adjustment can be deleted by setting - 0 in F20.
Procedure:
Switch to configuration and settings level. Display shows 0 0 0 0
