- Page 4 Please examine this product carefully. Make sure that the instrument is not damaged. If any damage occurred during shipment, please contact your local Hanna Instruments Office. Each HI96729 Ion Selective Meter is supplied complete with: • Sample Cuvettes and Caps (2 pcs.) •...
- Page 5 The validation procedure is extremely user friendly. Just use the exclusive Hanna Instruments ready‑made, NIST traceable standards to verify the performance of the instrument and recalibrate if necessary.

- Page 8 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 10: Operating Modes
OPERATING MODES • Measurement mode: default operation mode, enables both validation and measurement. • Calibration mode: may be entered by keeping CAL CHECK pressed for three seconds (the “CAL” tag appears), it enables calibration of the instrument. • GLP mode may be entered by pressing GLP/ (“GLP” appears), it enables consulting of user calibration date or restore factory calibration. - 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 zero reading Light High: There is too much light to perform a measurement. Please check the preparation of the zero cuvette.
- Page 12 Over Range: A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and re‑run the test. c) during calibration procedure Standard Low: The standard reading is less than expected. Standard High: The standard reading is higher than expected.
- Page 13 • For dosing the reagent, we recommend to use the supplied Hanna HI731342 automatic pipette. For a correct use of the Hanna Instruments automatic pipette, please follow the related Instruction Sheet. • Color or suspended matter in large amounts may cause interference, therefore these should be removed by treatment with active carbon and by prior filtration.
- Page 14 • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI731318 or a lint‑free cloth prior to insertion. • Shaking the cuvette can generate bubbles in the sample, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.
- Page 15 To compensate the meter for the sample turbidity or color, the measurement takes place in two phases. First, the meter is zeroed using the unreacted sample. After the reagents are added the reacted sample is measured. • Turn the meter on by pressing ON/OFF. The display briefly shows all tags on. •...
- Page 16 • Place the cuvette with the reacted deionized water (blank) into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. blank • Wait for 2 minutes, than press ZERO/CFM and the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase.
- Page 17 • Fill the same cuvette with unreacted sample up to 10 mL mark. Alternatively for most accurate results, use of another clean class A laboratory pipette is recommended. Fluoride Reagent to the cuvette by use of the 2000 µL automatic •...
- Page 18 • Press and hold READ /TIMER for three seconds. The display will show the countdown prior to measurement. The beeper is playing a beep at the end of countdown period, then press READ /TIMER. 3" Alternatively, wait for 2 minutes and just press READ /TIMER. In both cases, the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase.
- Page 19 Use the validation procedure to ensure that the instrument is properly calibrated. Warning: Do not validate the instrument with any standard solutions other than the Hanna Instruments CAL Check Standards, otherwise erroneous results will be obtained. For accurate validation, please perform test at room temperature: 18 to 25 °C (64.5 to 77.0 °F)
- Page 20 • Remove the cuvette. • Place the CAL Check Standard HI96729‑11 Cuvette B into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. • Press CAL Check and the lamp, cuvette and detector icons together with “CAL CHECK” will appear on the display, depending on the measurement phase.
- Page 21 Note: It is possible to interrupt calibration procedure at any time by pressing CAL CHECK or ON/OFF keys. Warning: Do not calibrate the instrument with standard solutions other than the Hanna Instruments CAL Check Standards, otherwise erroneous results will be obtained. For accurate validation, please perform test at room temperature: 18 to 25 °C (64.5 to 77.0 °F)
- Page 22 “STD LOW”, the standard value was too low. Verify that both CAL Check Standards HI96729-11 Cuvettes, A and B are free of fingerprints or dirt and that they are inserted correctly. Then the date of the last calibration (e.g.: ”01.08.2009”) appears on the display, or “01.01.2009”...

Page 23: Date Input
DATE INPUT • Press GLP/ to edit the desired year (2009‑2099). If the key is kept pressed, the year number is automatically increased. • When the correct year has been set, press ZERO/CFM or READ /TIMER to confirm. Now the display will show the month blinking. -
Page 24: Last Calibration Date
• The instrument displays “Stor” for one second and the calibration is saved. • The instrument will return automatically to the measurement mode by displaying dashes on the LCD. In the GLP mode, the last user calibration date can be verified and the factory calibration can be restored. - Page 25 • Press READ /TIMER to enter in the factory calibration restore screen. The instrument asks for confirmation of user calibration delete. • Press ZERO/CFM to restore the factory calibration or press GLP/ again to abort factory calibration restore. • The instrument briefly notifies “donE” upon restoration of factory calibration prior to returning to measurement mode.
