User Manual EE260 Heated Humidity and Temperature Probe for Meteorological Applications
6.4.1 Calibration and Adjustment at E+E Elektronik
Calibration and/or adjustment can be performed in the E+E Elektronik calibration laboratory. For
information on the E+E capabilities in ISO or accredited calibration please see www.eplusecal.com.
6.4.2 Humidity Calibration and Adjustment by the User
Depending on the level of accuracy required, the humidity reference can be:
Handheld device (e.g. Omniport 30), please see www.epluse.com/omniport30.
Humidity standards (e.g. Humidity Calibration Kit), please see www.epluse.com/EE260.
Please note:
It is of very high importance that for the RH calibration the RH and T sensing elements
are at the same temperature.
Please contact your sales representative for assistance.
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.

Please observe these important notes on changing the sensing element data:
■
The sensing element data generally only has informational character.
■
For all applications, an alleged drift of the device can be corrected using the offset correction or the
one/two point adjustment offered by the EE-PCS.
■
For very special requirements, the drift can be corrected acting upon the characteristic of the sensing
elements, i.e. upon the sensor data such as nominal capacity or humidity coefficient. This requires
deep knowledge about the sensing elements and the design of the measuring device.
