SPECIFICATIONS PRINCIPLE OF OPERATION Range Mg Hardness 0.00 to 2.00 mg/L Ca Hardness 0.00 to 2.70 mg/L Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and Total Hardness 0.00 to 4.70 mg/L matter. When a light beam crosses a substance, some of the radiation may be absorbed by Iron LR 0.00 to 1.60 mg/L Resolution 0.01 mg/L Total Hardness... -
Page 5: Functional Description
A microprocessor controlled special tungsten lamp emits radiation which is first optically FUNCTIONAL DESCRIPTION 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 6: Errors And Warnings
DISPLAY ELEMENTS 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. a) on zero reading Light High: There is too much light to perform a measurement. Please check the preparation of the zero cuvette. -
Page 7: General Tips For An Accurate Measurement
Battery low: The battery must be replaced soon. Under range: A blinking “0.00” indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure you use the same cuvette for reference (zero) and measurement. Dead battery: This indicates that the battery is dead and must Over Range: A flashing value of the maximum concentration be replaced. -
Page 8: Startup
• It is important that the sample does not contain any debris. STARTUP This would corrupt the reading. Prepare the instrument for measurement as follows: • Each time the cuvette is used, the cap must be tightened • Unpack the instrument by removing the dust protection sleeve from the instrument cuvette to the same degree. -
Page 9: Measurement Procedure
• Place the cuvette into the cuvette holder and MEASUREMENT PROCEDURE ensure that the notch on the cap is positioned securely into the groove. To compensate the meter for the sample turbidity or color, the measurement takes place in two •... -
Page 10: Validation Procedure
• Replace the cap and swirl the solution. • Turn the meter on by pressing ON/OFF. • Replace the cuvette into the cuvette holder • When the beeper sounds briefly and the LCD and ensure that the notch on the cap is displays dashes, the meter is ready. -
Page 11: Calibration Procedure
• Remove the cuvette. CALIBRATION PROCEDURE • Place the specific CAL CHECK Standard Note: It is possible to interrupt calibration procedure at any time by pressing CAL CHECK or Cuvette B into the cuvette holder, for: ON/OFF keys. Hardness: B, HI 96719-11 Warning: Do not calibrate the instrument with standard solutions other than the HANNA CAL CHECK Standards, otherwise erroneous results will be obtained. -
