Slide off the battery compartment cover on the back of the meter (see page 12), unwrap the battery and install it. To prepare HI 8564 for use connect the RH probe to the DIN socket on the top of the meter. be removed. Whenever the probe is to be used in a dusty or smoky environment, the filter must be kept on at all times. TEMPERATURE MEASUREMENTS Simply press the °C or °F keys to take the temperature readings directly from the same probe. Note: Press °C key to display the temperature in °C. °C "°C" is displayed when measuring temperature in degrees Centigrade. ON OFF Turn the meter on by pressing the ON/OFF key. ON OFF EXAMPLE: A temperature reading taken in degrees Centigrade would read: °C °C Using the HI 8564 or HI 93640 thermo-hygrometer is simple. However, the recommendations below should always be followed. RELATIVE HUMIDITY MEASUREMENTS · 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 the liquid has evaporated completely. In order to accelerate the evaporation process, the humidity sensor could be exposed to a current of air. For HI 93640 only: in order to obtain a faster response, the sintered filter should 6 Press °F key to read the same value in degrees Fahrenheit: °F °F If you experience any problems in taking measurements, please contact your dealer or the nearest Hanna Instruments Customer Service Department. 7 CALIBRATION All Hanna hygrometers have been precalibrated at the factory. Hanna Instruments uses state-of-the-art thermal humidity chambers for this purpose. It is generally recommended to have all hygrometers recalibrated at least once a year. For an accurate annual recalibration, contact your nearest Hanna Service Center. You can also check the status of your HI 8564 and perform a quick recalibration (with an accuracy of ±5%) by using the Hanna mini-calibration chambers HI 7101. The kits are composed of two thermally isolated chambers, each one equipped with a threaded cap and three bottles containing the appropriate precalibrated saturated salts to produce a known RH value. Li Cl 11. 1% Na Cl 75. 4% · When the salt has dissolved completely, add all the content of the second bottle of HI 7111. · Allow the solution obtained to cool, and then pour it into the chamber marked "RH 11. 1%", making sure that no residue remains on the walls of the glass container. Li Cl 11. 1% Na Cl 75. 4% CALIBRATION KIT · Seal the chamber well when not in use, as the LiCl solution is extremely hygroscopic and tends to capture the humidity present in the air causing the solution to expand in volume and to overflow from the container. H 2 CALIBRATION KIT Preparing the (HI 8564 only): Calibration Solutions O H2 · Pour approximately 12 cc of distilled water into the other chamber marked "RH 75. 4%". Li Cl 11. 1% Na Cl 75. 4% CALIBRATION KIT · Pour approximately 26 cc of distilled water into a glass container. 26 cc · Immerse this container into a bath of ice and water and shake briefly. · Slowly add the contents of a HI 7111 bottle containing LiCl into the glass container while continuing to shake. 8 · Add all the content of the HI 7121 bottle containing NaCl while continuously shaking the container to avoid the formation of lumps. Seal this container well when not in use. The calibration kit needs 4 hours for stabilization. Li Cl 11. 1% Na Cl 75. 4% CALIBRATION KIT Li C l 12 9 3 6 9 l Li C O 12 cc Na Cl 4h RH Calibration Procedure (HI 8564 only): · Bring the calibration kit to a temperature of approximately 20°C. [. . . ] In HI 8564 the trimmers are sensitive to Electrostatic Discharge. It is recommended to use an antistatic screwdriver during calibration. Any variation introduced by the user to the supplied equipment may degrade the instrument's EMC performance. To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24VAC or 60VDC. [. . . ]
