If any damage has occurred, notify your Dealer or closest Hanna Customer Service Center. [. . . ] In addition to %Brix, HI 96814 includes two other scales used in the wine industry: °Oechsle and °KMW. °Oechsle (°Oe) is mainly used in the German, Swiss and Luxenburgish winemaking industry to measure the sugar content of must. The °Oe scale is based on specific gravity at 20°C (SG20/20) and is the first 3 digits following the decimal point. °Oe = [(SG20/20) - 1] x 1000 °Klosterneuburger Mostwaage (°KMW) is used in Austria to measure the sugar content of must. °KMW is related to °Oe by the following equation: °Oe = °KMW x [(0. 022 x °KMW) + 4. 54] 1 °KMW is roughly equivalent to 1 %Brix or 5 °Oe. In addition to %Brix, HI 96813 also has a second scale that estimates the alcohol content in the finished wine in (% vol/vol). This is known as "potential" or "probable" alcohol since the conversion between sugar and alcohol depends on many factors such as the type of grapes, the grape maturity, the growing region and yeast fermentation efficiency and temperature. Since no fixed conversion factor is universally applicable, HI 96813 allows the user to taylor the instrument to their specific needs based on their experience. The first conversion is based on the %Brix value, with an adjustable conversion factor anywhere between 0. 50 and 0. 70 (0. 55 is a common value). Potential alcohol (% v/v) = (0. 50 to 0. 70) x %Brix One drawback of the above equation is that it does not take into account the nonfermentable sugars and extract. A second equation was also added that takes these factors into account and can give a more accurate estimate of the alcohol content in the finished wine. This conversion is named "C1" on the meter, and uses the following equation: Potential Alcohol (% v/v) = 0. 059 x [(2. 66 x °Oe) - 30] (C1) 6 FUNCTIONAL DESCRIPTION TOP VIEW 1. 8.

Do not spray water to any part of instrument except the "sample well" located over the prism. This includes most organic solvents and extremely hot or cold solutions. Absorb sample on soft tissue and rinse sample well with deionized or distilled water between samples. Do not use metallic tools such as needles, spoons or tweezers as these will scratch the prism. Cover sample well with hand if measuring in direct sun. · · · CALIBRATION PROCEDURE Calibration should be performed daily, before measurements are made, when the battery has been replaced, or between a long series of measurements. Two instrument test screens will be displayed briefly; all LCD segments followed by the percentage of remaining battery life. Using a plastic pipette, fill the sample well with distilled or deionized water. Note: If the ZERO sample is subject to intense light such as sunlight or another strong source, cover the sample well with your hand or other shade during the calibration. 9 3. [. . . ] · Insert the back battery cover and fasten it by turning clockwise to engage. WARRANTY HI 96811, HI 96812, HI 96813 and HI 96814 are warranted for two years against defects in workmanship and materials when used for its intended purpose and maintained according to the instructions. Damage due to accident, misuse, tampering or lack of prescribed maintenance is not covered. If under warranty, report the model number, date of purchase, serial number and the nature of the failure. If the repair is not covered by the warranty, you will be notified of the charges incurred. [. . . ]
