Resolution
Make sure that the sensor is configured for the
correct cell constant.
Make sure that the sensor is configured for the
correct cell constant.
Make sure that the sensor is held in air during
zero calibration and is not located near radio
frequency or electromagnetic interference.
Make sure that the cable is shielded by metal
conduit.
Make sure that the correct temperature
element is selected. Refer to
sensor
on page 8.
Power off and power on the controller. Contact
technical support.
Examine the wiring and connections for the
sensor and for the module (or digital gateway).
Make sure that the terminal block is fully
inserted into the module, if applicable.
Make sure that the sensor is configured for the
correct cell constant.
