Page 4: General
Intended use The EE211 is intended for the measurement of relative humidity (RH) and temperature (T) in environment with continuous high humidity. The use of the EE211 other than described in this manual is not recommended. The manufacturer cannot be held responsible for damages as a result of incorrect handling, installation and maintenance of the device. -
Page 5: Mounting And Start-Up
Based on the measured values humidity and temperature, the EE211 calculates the dew point temperature Td whereas the separate, interchange- able T-probe measures the ambient temperature. Ultimately, out of Td and T, the device calculates the relative humidity RH as well as several other parameters like absolute humidity, mixing ratio, wet bulb temperature or enthalpy. -

(approx. 5 °C = 9 °F) means max. 76 % RH humidity at the sensors and enables following benefits: • The sensing head of EE211 stays dry even under condensing conditions, which prevents dust and dirt from sticking to the sensor and leads to outstanding long-term stability. -

• Insert the M20 cable gland included in the scope of supply into the corresponding opening of the EE211 basis unit and fix it tight with the nut. Alternatively, it is possible to install a 1/2” conduit fitting (not included in the scope of supply). -
Page 8: Setup
Setup The EE211 is ready to use and does not require any configuration by the user. The factory setup of EE211 corresponds to the type number ordered. For ordering guide please see data sheet at www.eplu- se.com/ee211. If needed, the user can change the factory setup by using the USB configuration adapter (cod HA011066) and the EE-PCS, Product Configuration Software. -

Page 12: Maintenance
Omniport 30 can be optionally supplied with an accredited calibration certificate. See E+E calibration brochure at www.eplusecal.com. • For multiple point calibration or 2-point adjustment for RH and T, the EE211 as a whole (both probes) shall be placed in a climate chamber. -
Page 13: Individual Calibration / Adjustment Of The T Probe
In case of individual adjustment, the adjustment data is stored in the T probe, the factory setup of the EE211 basis unit is not altered. Consequently, the T probe can be readjusted or replaced at any time without the need of readjusting the EE211 basis unit. -
