Dear Customer, Thank you for choosing a Hanna product. This manual will provide you with the necessary information for the correct use of the instrument. Please read it carefully before using the meter. If you need additional technical information, do not hesitate to e-mail us at tech@hannainst.com. This instrument is in compliance with directives. TABLE OF CONTENTS PRELIMINARY EXAMINATION ...............................................................................................
CE DECLARATION OF CONFORMITY Recommendations for Users Before using these products, make sure that they are entirely suitable for your specific application and for the environment in which they are used. Operation of these instruments may cause unacceptable interferences to other electronic equipments, this requiring the operator to take all necessary steps to correct interferences. Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance.
GENERAL DESCRIPTION BATTERIES REPLACEMENT The HI 83740 is an auto-diagnostic portable microprocessor meter that benefits from Hanna’s years of experience as a manufacturer of analytical instruments. It has an advanced optical system based on a special tungsten lamp and a narrow band interference filter that allows most accurate and repeatable readings. All instruments are factory calibrated.
• Insert the zero (cuvet #1) into the holder and close the lit. #1 (Zero) • Press ZERO and “----” will blink on the display. • After a few seconds the display will show “-0.0-”. The meter is now zeroed and ready for measurement Note: If the “L Lo” (Low Light) message appears, the sample must be diluted. See “General tips for an accurate measurement” (page 12). • Remove the cuvet from the instrument. • Insert the reacted sample (cuvet #2) into the holder and close the lid.
PRINCIPLE OF OPERATION Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance, some of the radiation may be absorbed by atoms, molecules or crystal lattices.
• Add 4 full spoons of reagent C to each vial. x4 #1 x4 #2 • Using the other supplied spoon, add 4 full spoons of reagent D to each vial. x4 A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed to the sample contained in the cuvet. The optical path is fixed by the diameter of the cuvet. Then the light is spectrally filtered to a narrow spectral bandwidth, to obtain a light beam of intensity Io or I.
FUNCTIONAL DESCRIPTION MEASUREMENT PROCEDURE INSTRUMENT DESCRIPTION • Turn the instrument on by pressing ON/OFF. 1) 2) 3) 4) 5) 6) 7) 8) FRONT Lid Cuvet Holder Liquid Crystal Display (LCD) ON/OFF key, to turn the meter on and off ZERO key, to zero the meter TIMER key, to activate a countdown READ key, to perform measurement Power Socket 12V to 20V DC 2.5 Watt REAR • When the LCD displays “---”, it is ready.
• Diluting procedure of the wine sample in case the “L Lo” (Low Light) message appears: use the pipette to fill the glass vials with 5 mL of wine sample (both vials), then fill the vials up to the 15 mL mark with HI 837421 Wine Solvent-1. This is the diluted wine sample. The final reading must be multiplied by 3 to compensate for dilution. GUIDE TO DISPLAY CODES 15 mL 5 mL This prompt appears for a few seconds each time the instrument is turned ON.
Indicates that the batteries are dead and must be replaced. After this message appears, the instrument is switched off. Change the batteries and restart the meter. ERROR MESSAGES The meter has lost its configuration. Contact your dealer or the nearest Hanna Customer Service Center. a) on zero reading: “Light high”: there is too much light to perform a measurement. Please check the preparation of the zero cuvet. “Light low”: there is not enough light to perform a measurement. Dilute the sample.
