GENERAL DESCRIPTION SIGNIFICANCE AND USE The HI 96785 is an auto diagnostic portable microprocessor meter that benefits from Hanna’s years of experience as a manufacturer of analytical instruments. It has the advanced optical system based on two special tungsten lamps and two narrow band interference filters that allows most accurate and repeatable readings. All instruments are factory calibrated and the electronic and optical design minimizes the need of frequent calibration.
SPECIFICATIONS Range Resolution Accuracy Typical EMC Deviation Light Source Light Detector Method Environment Battery Type Auto-Shut off Dimensions Weight REQUIRED STANDARD Description Glycerol 0 to 150 mm Pfund 1 mm Pfund ±2 mm Pfund @ 80 mm Pfund 1 mm Pfund Tungsten lamp Silicon Photocell with narrow band interference filter @ 420 nm and 525 nm Direct Measurement 0 to 50°C (32 to 122°F); max 95% RH non-condensing 1 x 9 volt After 10' of non-use in measurement mode; with last reading reminder.
FUNCTIONAL DESCRIPTION ERRORS AND WARNINGS 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. INSTRUMENT DESCRIPTION 1) 2) 3) 4) 5) CAL key READ key ON/OFF key Liquid Crystal Display (LCD) Cuvette holder a) on calibration Light High: There is too much light to perform a measurement. Please check the preparation of the calibration cuvette.
Under range: A blinking “0” indicates that the sample absorbs less light than the calibration reference. Check the procedure and recalibrate the instrument. GENERAL TIPS FOR AN ACCURATE MEASUREMENT The instructions listed below should be carefully followed during testing to ensure best accuracy. Over Range: A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range.
STARTUP 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. • Do not place the instrument under direct sun light. MEASUREMENT PROCEDURE To compensate the meter for the sample turbidity or color, the measurement takes place in two phases.
ACCESORIES BATTERY MANAGEMENT To save battery, the instrument shuts down after 10 minutes of non-use in measurement 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 350 measurements, depending on the light level. The remaining battery capacity is evaluated at the instrument startup and after each measurement.
