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 POWER CONNECTION AND BATTERY MANAGEMENT The 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.
