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, and 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 as the 10 mL mark.
• Proper use of the powder reagent packet: (a) use scissors to open the powder packet; (b) push the edges of the packet to form a spout; (c) pour out the content of the packet. USING CUVETTES • Proper mixing is very important for reproducibility of the measurements. The right way of mixing a cuvette is specified for each method in the related chapter. (a) invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position.
• Pay attention to push the cuvette completely down in the holder and to align the white point on the cap to the indexing mark on the meter. • In order to avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic stopper and then the black cap. • Each time the cuvette is used, the cap must be tightened to the same degree. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and free of fingerprints, oil or dirt.
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. Avoid breathing released vapors.
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.
• After the desired method is selected, follow the measurement described in the related section. • Before performing a test you should read all the instructions carefully.
