The measurement process is carried out in two phases: first the meter is zeroed and then the actual measurement is performed. The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both the measurement and the calibration (zeroing) cuvette are optically identical to provide the same measurement conditions. Most methods use the same cuvette for both, so it is important that measurements are taken at the same optical point.
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: refere to Sample Preparation Chapter (page 17). • 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.
• 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. 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.
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.
SETUP In the Setup mode the instrument’s parameters can be changed. Some parameters affect the measuring sequence and others are general parameters that change the behavior or appearance of the instrument. Press SETUP to enter the setup mode. Press ESC or SETUP to return to the main screen. A list of setup parameters will be displayed with currently configured settings. Press HELP for additional information. Press the s t keys to select a parameter and change the value as follows: Backlight Values: 0 to 8.
Instrument ID Option: 0 to 9999. This option is used to set the instrument’s ID (identification number). The instrument ID is used while exchanging data with a PC. Press the Modify key to access the instrument ID screen. Press the s t keys in order to set the desired value. Press the Accept key to confirm the value or ESC to return to the setup menu without saving the new value.
