TIPS FOR AN ACCURATE MEASUREMENT The instructions listed below should be carefully followed during testing to ensure most accurate results. • Color or suspended matter in large amounts may cause interference, they should be removed by treatment with active carbon and filtration. • Ensure the cuvette is filled correctly: the liquid in the cuvette forms a convexity on the top; the bottom of this convexity must be at the same level of the 10 mL mark.
Pay attention to push the cuvette completely down in the holder. HEALTH & SAFETY The chemicals contained in the reagent kits may be hazardous if improperly handled. Read the Material 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.
OPERATIONAL GUIDE • After the desired method was selected, follow the measurement described in the related section. • Before performing a test you should read all the instructions carefully. POWER CONNECTION AND BATTERY MANAGEMENT The meter can be powered from an AC/DC adapter (included) or from the built-in rechargeable battery.
