  • 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 HI96705 Ion Selective Meter is supplied complete with: • Sample Cuvettes and Caps (2 pcs.) •...
  • Page 5 HI96705 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.

    Range 0 to 2.00 mg/L Resolution 0.01 mg/L Accuracy ±0.03 mg/L ±3% of reading @ 25 ºC (77 ºF) Light Source Tungsten lamp Light Detector Silicon Photocell with narrow band interference filter @610 nm Adaptation of the ASTM D859 of heteropoly blue method. The reaction Method between silica and reagents causes a blue tint in the sample.
  • Page 7 The optical system of Hanna Instruments’ HI96’ colorimeter is based on special tungsten lamp and narrow-band interference filters to guarantee both high performance and reliable results.
  • 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 The instructions listed below should be carefully followed during testing to ensure best accuracy. • Color or suspended matter in large amounts may cause interference, therefore these should be removed by treatment with active carbon and by prior filtration. • For a correct filling of the cuvette: the liquid in the cuvette 10ml 10mL forms a concavity on the top;...
  • Page 14 • It is important that the sample does not contain any debris. This would corrupt the reading. • Each time the cuvette is used, the cap must be tightened to the same degree. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt.
  • 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 • Wait for 1 minute. This is the blank. • Place the cuvette into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. • Press ZERO/CFM and the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase.
  • Page 17 • Replace the cuvette into the holder and ensure that the notch on the cap is positioned securely into the groove. • Press and hold READ /TIMER for three seconds. The display will show the countdown prior to measurement. An audible “beep” indicates the end of the countdown period. •...
  • Page 18 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. • Turn the meter on by pressing ON/OFF.
  • Page 19 • After a few seconds, the display will show “-0.0-”. The meter is now zeroed and ready for validation. • Remove the cuvette. • Place the CAL Check Standard HI96705-11 Cuvette B into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. •...
  • Page 20 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.
  • Page 21 • After a few seconds the display will show “-0.0-”. The meter is now zeroed and ready for calibration. The blinking “READ” asks for reading calibration standard. • Remove the cuvette. • Place the CAL Check Standard HI96705-11 Cuvette B into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove.
  • Page 22 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 23: Last Calibration Date

    • Press ZERO/CFM to save the calibration date. • The instrument displays “Stor” for one second and the calibration is saved. • The instrument will return automatically to measurement mode by displaying dashes on the LCD. In GLP mode, the last calibration date can be verified and the factory calibration can be restored. LAST CALIBRATION DATE To display the calibration date: •...
  • Page 24 FACTORY CALIBRATION RESTORE It is possible to delete the calibration and restore factory calibration. • Press GLP/ to enter GLP mode. • Press READ /TIMER to enter in the factory calibration restore screen. The instrument asks for confirmation of user calibration delete. •...
  • Page 25 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 “ZERO” means that a new zero has to be performed.
