Cleaning the Sensing Head and Filter Replacement

In case of dusty, oily and polluted environment
▪
The filter cap shall be replaced once in a while with an E+E original one. A polluted filter cap causes longer
response time of the device.
▪
If needed, the sensing head can be cleaned. For cleaning instructions please see www.epluse.com/ee310.

RH and T Calibration and Adjustment

Humidity calibration and adjustment
Depending on the application and the requirements of certain industries, there might arise the need for periodical
humidity calibration (comparison with a reference) or adjustment (bringing the device in line with a reference).
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.
Calibration and adjustment by the user
Depending on the level of accuracy required, the humidity reference can be:
▪
Humidity Calibrator (e.g. Humor 20), please see www.epluse.com/humor20.
▪
Handheld Device (e.g. Omniport30), please see www.epluse.com/omniport30.
▪
Humidity Calibration Kit (e.g. E+E Humidity Standards), please see www.epluse.com/ee310.
Perform 1 or 2 point adjustment via PCS10 Product Configuration Software or via display (see below).
