- Page 5 HI96759 is an auto diagnostic portable microprocessor meter that benefits from Hanna Instruments’ years of experience as a manufacturer of analytical instruments. It has the advanced optical system based on a special tungsten lamp and a narrow band interference filter that allows most accurate and repeatable readings.
- Page 6 The primary characteristic for classifying maple syrup is color. When syrup is very light in color, as matching the minimum light transmittance standards, the grade assigned to syrup is high. When syrup color is dark, the grade is low. Color classes are expressed in percent of light transmission as compared to an analytical Glycerol Standard Reference fixed at one hundred percent transmission.

- Page 9 A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed to the sample contained in the cuvette. The optical path is fixed by the diameter of the cuvette. Then the light is spectrally filtered to a narrow spectral bandwidth, to obtain a light beam of intensity I or I.

- Page 11 The instrument shows clear messages when erroneous condition appears. Messages are also displayed when the obtained values are outside expected range. The beeper is playing a beep on errors. a) on calibration Light High: There is too much light to perform a measurement. Please check the preparation of the calibration cuvette.
- Page 12 d) other errors and warnings Cap error: Appears when external light enters in the analysis cell. Assure that the cuvette cap is present. Cooling lamp: The instrument waits for the lamp to cool down. Battery low: The battery must be replaced soon. Dead battery: This indicates that the battery is dead and must be replaced.
- Page 13 The instructions listed below should be carefully followed during testing to ensure best accuracy. • Use matched square cuvettes, having 4 clear faces and 10 mm path length. • Do not touch the cuvette walls with hands. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt.
- Page 14 Prepare the instrument for measurement as follows: • Unpack the instrument by removing the dust protection sleeve from the instrument cuvette holder. • Place the battery in the instrument as described in the “BATTERY REPLACEMENT” chapter. • Place the instrument on a flat table. •...
- Page 15 • Place the cuvette into the cuvette holder paying attention to the direction of the light indicated by the arrow on the instrument. Then put the light shield cap on and ensure that the notch on the cap is positioned securely into the groove. •...

- Page 17 To save battery, the instrument shuts down after 10 minutes of non‑use in measurement mode and after 1 hour of non‑use in calibration mode. If a valid measurement was displayed before auto‑shut off, the value is displayed when the instrument is switched on. The blinking “CAL” means that a new calibration has to be performed. One fresh battery lasts for around 750 measurements, depending on the light level.
- Page 18 To replace the instrument’s battery, follow the steps: • Turn the instrument off by pressing ON/OFF. • Turn the instrument upside down and remove the battery cover by turning it counterclockwise. • Extract the battery from its location and replace it with a fresh one. •...
