Important!
Contact the E+E sales representative before any attempt of acting upon the sensing
element data!
■
Caution!
Upon changing the sensing element data, the original data is lost. There is no way to
automatically return to the original sensor data. Please make sure to note and save the original
sensing element data before making any change!
6.4.3 Temperature Calibration and Adjustment by the User
For a reproducible T calibration or adjustment, it is recommended to measure the Pt100 of the EE260
in a liquid bath. This reduces the T inhomogeneity surrounding the probe to a minimum. It must be
ensured to use an inert, nonconductive liquid which does not chemically contaminate the sensor
element (e.g. GALDEN HT200).
Please note:
When the calibration/adjustment procedure with the help of EE PCS starts, both heating
modes of the EE260 are disabled automatically if they have
on
status. At the end of the procedure the
heating comes back to
on
automatically.
The temperature reference (T-Ref) shall be located at the same level as the Pt100 of the EE260.

6.5 Error Indication on the Analogue Output (NAMUR)
The EE260 features an error indication on its analogue outputs according to the NAMUR NE 043
recommendations (Standardization of the Signal Level for the Failure Information of Digital Transmitters,
Edition 2003-02-03, see
www.namur.net/en/recommendations-and-worksheets/current-nena.html
The feature is enabled by factory default and can be disabled with the EE-PCS Product Configuration
Software, see above.
