10 11POWER CONNECTION AND BATTERY MANAGEMENTThe meter can be powered from an AC/DC adapter (included) or from the built-in rechargeable battery.Note: Always turn the meter off before unplugging it to ensure no data is lost.When the meter switches ON, it verifies if the power supply adapter is connected. The battery icon on theLCD will indicate the battery status:- battery is charging from external adapter - battery fully charged (meter connected to AC/DC adapter)- battery capacity (no external adapter) - battery Low (no external adapter)- battery Dead (no external adapter)OPERATIONAL GUIDE• Turn ON the instrument via the ON/OFF power switch.• The meter will perform an autodiagnostic test. During this test, the Hanna Instrument logo will appear onthe LCD. After 5 seconds, if the test was successful, the last selected method will appear on the display.• In order to select the desired method press METHOD and a screen with the available methods will appear.• Press V W keys to highlight the desired method. Press Select.METHOD SELECTIONMETHOD REFERENCE TABLEHI 83203 - AQUACULTUREMethod Method Pagedescription1 Ammonia MR 162 Ammonia LR 183 Free Chlorine 204 Total Chlorine 235 Copper HR 266 Copper LR 287 Nitrate 30HEALTH & SAFETYThe chemicals contained in the reagent kits may be hazardous if improperly handled. Read theMaterial Safety Data Sheet (MSDS) before performing tests.Safety equipment: Wear suitable eye protection and clothing when required, and follow instructions carefully.Reagent spills: If a reagent spill occurs, wipe up immediately and rinse with plenty of water.If reagent contacts skin, rinse the affected area thoroughly with water. Avoid breathing released vapors.• It is possible to take multiple readings in a row, but it is recommended to take a new zero reading foreach sample and to use the same cuvette for zeroing and measurement when possible (for most preciseresults follow the measurement procedures carefully).• Discard the sample immediately after the reading is taken, or the glass might become permanently stained.• All the reaction times reported in this manual are at 20°C (68°F). As a general rule of thumb, theyshould be doubled at 10°C (50°F) and halved at 30°C (86°F).REAGENT BLANK CORRECTION• Some methods require a “reagent blank correction”. The blank and the sample are prepared exactlyin the same way, only the blank is deionized water instead of sample.A blank cuvette may be used more than once: stability and storing conditions are described for eachmethod in the related chapter.INTERFERENCES• In the method measurement section the most common interferences that may be present in an averagewastewater matrix have been reported. It may be that for a particular treatment process othercompounds do interfere with the method of analysis.Method Method Pagedescription8 Nitrite HR 329 Nitrite LR 3410 Dissolved Oxygen 3611 pH 3812 Phosphate HR 4013 Phosphate LR 42
