• Otherwise select in the main menu the menu option Barcode
Programs and insert a zero cell (depending on work
instruction) into the cell compartment (1).
Note: To obtain further information on the Help Guide ("Information"
symbol).
The measurement is started automatically and the results are shown.
Note: To define a sample dilution, press the Dilution key in the toolbar.
To evaluate other cell tests and other parameters insert the prepared cell
into the cell compartment and read off the result.
Note: The control bar, which is shown on the right on the display, shows
the relationship of the measurement result with the measurement range.
The blue bar shows the reading result independently of any dilution factor
that was entered.

Single Wavelength (absorbance, concentration and
transmittance readings)
The Single Wavelength mode can be used in three ways. For sample
readings at a single wavelength, the instrument can be programmed to
measure the absorbance, % transmittance or concentration of the
analyte.
• Absorbance readings: The light absorbed by the sample is
measured in absorbance units.
• % Transmittance measures the percent of the original light that
passes through the sample and reaches the detector.
• Turning on the concentration factor allows selection of a specific
multiplier for converting absorbance readings to concentration. In a
graph of concentration versus the absorbance, the concentration
factor is the slope of the line.
Set up Single Wavelength mode
1. Press Single Wavelength in the Main Menu.
2. Press Options for Parameter Setup.
