[. . . ] FUNCTIONAL DESCRIPTION PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it to make sure that no damage has occurred during shipping. [. . . ] However, the recommended procedure is as follows: · The end of the humidity detector should be exposed to a current of air moving at 0. 5 m (20") per second or more. · In the absence of air movement, the response can be accelerated by moving the probe. · The probe sensor must never come into contact with water or other liquids. If this should happen, or if condensation causes drops to form on the surface of the humidity sensor, turn off the instrument and wait until this water has evaporated completely. In order to accelerate the evaporation process, the humidity sensor could be exposed to a current of air. CALIBRATION All Hanna hygrometers are calibrated with reference to NIST certified instruments. In addition, the Hanna Service Centers are equipped with state-of-the-art calibration chambers.
