User manual HANNA INSTRUMENTS HI 96803

[. . . ] The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (Internationally recognized body for Sugar Analysis). Temperature (in °C or °F) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes. Key features include: · Dual-level LCD · Automatic Temperature Compensation (ATC) · Easy setup and storage · Battery operation with Low Power indicator (BEPS) · Automatically turns off after 3 minutes of non-use.

Do not spray water to any part of instrument except the "sample well" located over the prism. The instrument is intended to measure Glucose solutions. Do not expose instrument or prism to solvents that will damage it. This includes most organic solvents and extremely hot or cold solutions. Particulate matter in a sample may scratch the prism. Absorb sample on soft tissue and rinse sample well with deionized or distilled water between samples. Use plastic pipettes to transfer all solutions. Do not use metallic tools such as needles, spoons or tweezers as these will scratch the prism.

ATC seg ment b linking SETUP seg ment b linking 6 7 CALIBRATION 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; a LCD segment followed by the percentage of remaining battery life. When LCD displays dashes, the instrument is ready. MEASUREMENT Verify the instrument has been calibrated before taking measurements. Wipe off prism surface located at the bottom of the sample well. 2. [. . . ] Example with 25%: % 25 BATTERY REPLACEMENT To replace the instrument's battery, follow these steps: · Turn the instrument OFF by pressing the ON/OFF key. · Turn instrument upside down and remove the battery cover by turning it counterclockwise. g Glucose 25. 000 g Water 75. 000 Total g Total 100. 000 · Extract the battery from its location. · Replace with fresh 9V battery making certain to observe polarity. · Insert the back battery cover and fasten it by turning clockwise to engage. TO CHANGE TEMPERATURE UNITS To change the temperature measurement unit from Celsius to Fahrenheit (or vice versa), follow this procedure. Press and hold the ON/OFF key continuously for aproximately 8 seconds. [. . . ]
