6 Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation andmatter. 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 ...

9 The instrument shows clear messages when erroneous condition appears. Messages are also displayedwhen 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 preparatio...

1 1 The instructions listed below should be carefully followed during testing to ensure best accuracy. • For a correct filling of the cuvet: the liquid in the cuvet forms a concavity on the top; the bottom of this concavity must beat the same level of the 10 mL mark. • Proper use of the powder reage...

1 2 Prepare the instrument for measurement as follows:• Unpack the instrument by removing the cuvet holder protection from the instrument cuvet holder.• Place the battery in the instrument as described in the “BATTERY REPLACEMENT” chapter (see pag.22). • Place the instrument on a flat table.• Do not...

1 5 • Turn the meter on by pressing ON/OFF . • Press ZERO/CFM and the instrument status indicator icons will appear, depending onthe measurement phase. • P l a c e t h e C A L C H E C K ™ ™ ™ ™ ™ S t a n d a r d Cuvet A into the cuvet holder and ensurethat the notch on the cap is positionedsecurely ...

1 7 Note: It is possible to interrupt calibration procedure at any time by pressing CAL CHECK or ON/OFF . Warning : Do not calibrate the instrument with standard solutions other than the HANNA CAL CHECK™ Standards, otherwise erroneous results will be obtained. For accurate Validation and Calibration...

1 9 • Press GLP/ to edit the desired day (01-31). If the key is kept pressed, the daynumber is automatically increased. Note: It is possible to change the editing from day to year and to month bypressing READ /TIMER . • Press GLP/ to edit the desired year (2000-2099). If the key is kept pressed,the ...

2 0 • Press READ /TIMER to enter in the factory calibration restore screen. Theinstrument asks for confirmation beforedeleting the last calibration. • Press ZERO/CFM to restore the factory calibration or press GLP/ again to abort factory calibration restore. In the GLP mode, the last user calibratio...

2 1 • The instrument briefly notifies “done” when restores factory calibration andreturns to measurement mode . 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...
