SPECIFICATIONS Life of the instrument Silicon Photocell 0 to 50°C (32 to 122°F); max 90% RH non-condensing Power Supply external 12 Vdc power adapter built-in rechargeable battery Dimensions 235 x 200 x 110 mm (9.2 x 7.87 x 4.33") Weight 0.9 Kg For specifications related to each method (e.g. range, resolution, etc.) refer to the related measurement section. Light Life Light Detector Environment PRECISION AND ACCURACY Precision is how closely repeated measurements agree with each other.
Where: -log I/Io= Absorbance (A) Io = intensity of incident light beam I = intensity of light beam after absorption ελ = molar extinction coefficient at wavelength λ c = molar concentration of the substance d = optical path through the substance Therefore, the concentration "c" can be calculated from the absorbance of the substance as the other factors are known.
FUNCTIONAL DESCRIPTION INSTRUMENT DESCRIPTION 1) 2) 3) 4) 5) 6) 7) 8) Open Cuvette Lid Indexing mark Cuvette point Liquid Crystal Display (LCD) Splash proof keypad ON/OFF power switch Power input connector USB connector 6
KEYPAD DESCRIPTION The keypad contains 8 direct keys and 3 functional keys with the following functions: Press to perform the function displayed above it on the LCD. ESC Press to exit the current screen. Press to access the select method menu. Press to move up in a menu or a help screen, to increment a set value, to access second level functions. Press to move down in a menu or a help screen, to decrement a set value, to access second level functions. Press to log the current reading.
(c) take out the syringe and clean the outside of the syringe tip. Be sure that no drops are hanging on the tip of the syringe, if so eliminate them. Then, keeping the syringe in vertical position above the cuvette, push the plunger down into the syringe until the lower edge of the seal is exactly on the 0.5 mL mark. Now the exact amount of 0.5 mL has been added to the cuvette, even if the tip still contains some solution.
USING CUVETTES • Proper mixing of the cuvette is done by shaking the cuvette, moving the cuvette up and down. The movement may be gentle or vigorous. This mixing method is indicated with “shake gently” or “shake vigorously”, and one of the following icons: shake gently shake vigorously • 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.
• Do not let the reacted sample stand too long after reagent is added. For best accuracy, respect the timings described in each specific method. • It is possible to take multiple readings in a row, but it is recommended to take a new zero reading for each sample and to use the same cuvette for zeroing and measurement when possible (for most precise results follow the measurement procedures carefully). • Discard the sample immediately after the reading is taken, or the glass might become permanently stained.
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. DATA MANAGEMENT The instrument features a data log function to help you keep track of all your analysis. The data log can hold 200 individual measurements. Storing, viewing and deleting the data is possible using the LOG and RCL keys.. Storing data: You can store only a valid measurement.
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 keys to select a parameter and change the value as follows: Backlight Values: 0 to 8.
Date / Time This option is used to set the instrument’s date and time. Press the Modify key to change the date/time. Press the W X functional keys to highlight the value to be modified (year, month, day, hour, minute or second). Use the keys to change the value. Press the Accept key to confirm or ESC to return to the setup without saving the new date or time. Time format Option: AM/PM or 24 hour. Press the functional key to select the desired time format.
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 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.
