Page 7: 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 8: Principle Of Operation
PRINCIPLE OF OPERATION Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance, some of the radiation may be absorbed by atoms, molecules or crystal lattices. If pure absorption occurs, the fraction of light absorbed depends both on the optical path length through the matter and on the physical-chemical characteristics of the substance according to the Lambert-Beer Law: = ε... - Page 9 The photoelectric cell collects the radiation I that is not absorbed by the sample and converts it into an electric current, producing a potential in the mV range. The microprocessor uses this potential to convert the incoming value into the desired measuring unit and to display it on the LCD.

Page 12: 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 13 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 14: 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 15: Startup
• 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 16: Range Selection
RANGE SELECTION The HI 96101 can measure pH when range P1 is selected, Free Chlorine when range P2 is selected, Total Chlorine when range P3, Cyanuric Acid when range P4, Iodine when range P5, Bromine when range P6, Iron LR when range P7 are selected. To change the active range follow the procedure: •... - Page 17 • 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. Note: Pay attention that the selected range is the one desired to run measurements. If not, change the range following the instructions from Range Selection.

Page 28: 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 29: Calibration Procedure
The reading should be within specifications as reported in the CAL CHECK Standard Certificate. If the value is found out of the specifications, please check that the cuvettes are free of fingerprints, oil or dirt and repeat validation. If results are still found out of specifications, then recalibrate the instrument. -
