Page 6: Precision And Accuracy
PRECISION AND ACCURACY Precision is how closely repeated measurements agree with each other. Precision is usually expressed as standard deviation (SD). Accuracy is defined as the nearness of a test result to the true value. Although good precision suggests good accuracy, precise results can be inaccurate. - Page 7 Therefore, the concentration "c" can be calculated from the absorbance of the substance as the other factors are known. Photometric chemical analysis is based on the possibility to develop an absorbing compound from a specific chemical reaction between sample and reagents. Given that the absorption of a compound strictly depends on the wavelength of the incident light beam, a narrow spectral bandwidth should be selected as well as a proper central wavelength to optimize measurements.

Page 10: Errors And Warnings
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. a) on zero reading Light High: There is too much light to perform a measurement. Please check the preparation of the zero cuvette. - Page 11 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 12: General Tips For An Accurate Measurement
GENERAL TIPS FOR AN ACCURATE MEASUREMENT 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. •... -
Page 13: Startup
• 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 HI 731318 or a lint-free cloth prior to insertion. • Shaking the cuvette can generate bubbles in the sample, causing higher readings. -
Page 14: Range Selection
RANGE SELECTION The HI 96710 can measure pH when range P1 is selected, Free Chlorine when range P2 is selected or Total Chlorine when range P3 is selected. To change the active range follow the procedure: • Turn the meter on by pressing ON/OFF. The display briefly shows all tags on. - Page 15 • When the beeper sounds briefly and the LCD displays dashes, the meter is ready. The blinking “ZERO” indicates that the instrument needs to be zeroed first. • Pay attention to the selected range. To change the range, simply press RANGE/GLP/ .
- Page 16 • Press READ/ /TIMER. The lamp, cuvette and detector icons will appear on the display, depending on the measurement phase. • The instrument directly displays the pH measured value on the Liquid Crystal Display. FREE CHLORINE MEASUREMENT • Fill the cuvette up to the mark with 10 mL of unreacted sample and replace the cap.
- Page 17 • Replace the cuvette into the cuvette 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”...

Page 20: Validation Procedure
VALIDATION PROCEDURE 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 CAL CHECK Standards, otherwise erroneous results will be obtained. Note: The validation is performed only for the selected parameter. For full validation of the instrument, the following procedure must be performed for each parameter. -
Page 21: Calibration Procedure
• Press CAL CHECK and the lamp, cuvette and detector icons together with “CAL CHECK” will appear on the display, depending on the measurement phase. • At the end of the measurement the display will show the validation standard value. The reading should be within specifications as reported in the CAL CHECK Standard Certificate. - Page 22 • Press ZERO/CFM and the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase. • 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.
- Page 23 DATE INPUT • Press RANGE/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.

• The instrument will return automatically to 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. LAST CALIBRATION DATE To display the calibration date: •... -
Page 25: Battery Management
BATTERY MANAGEMENT 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. -
