Single wavelength readings are:
Absorbance readings: The light absorbed by the sample is
measured in absorbance units.
Transmittance reading (%): Measures the percent of the
original light that passes through the sample and reaches the
detector.
Concentration readings: A concentration factor can be
entered to enable the measured absorbance values to be
converted into concentration values.
In the Multi Wavelength mode, absorbance (Abs) or
percentage transmittance (%T) is measured at up to four
wavelengths and absorbance differences and absorbance
relationships are calculated. Simple conversions into
concentrations can also be carried out.
A wavelength scan shows how the light from a sample is
absorbed over a defined wavelength spectrum. This function
can be used to determine the wavelength at which the
maximum absorbance value can be measured. The
absorbance behavior is displayed graphically during the
scan.
The time scan records the absorbance or % transmittance at
a wavelength over a defined time.

Barcode Programs
A special barcode reader in cell compartment #1 automatically reads the
barcode on the 13 mm cuvette/vial as the cuvette/vial completes a single
rotation. The instrument uses the barcode identification to automatically
set the correct wavelength for the analysis and calculates the result
immediately with the help of stored factors.
In addition, readings are recorded at 10 different positions during a
rotation. A special outlier-elimination program is run and then the
average of the measured values is calculated. Cell and round cell faults
and contaminations are detected and therefore a very precise result is
determined.
Perform a barcode test

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.

Wavelength Scan mode – recording of absorbance
and transmission spectrums
In the Wavelength Scan mode, the absorbance of the light in a solution
over a defined wavelength spectrum is measured.
The reading results can be displayed as a curve, as percentage
transmittance (%T) or as Absorbance (Abs). The collected data can be
printed as a table or a curve.
The data is available for formatting changes. These include automatic
scaling and zoom functions. Maximum and minimum values are
determined and shown as a table.
The cursor can be moved to any point on the curve for the purpose of
reading off the absorbance or transmittance value and the wavelength.
The data associated with each data point can also be shown as a table.

Perform a wavelength scan
After selecting all scan parameters, record a base line (initial zero
reading). If a scan parameter is changed, a new base line must be
recorded. After the scan of the baseline the device is ready for the
scanning of one or several samples.
1. Select in the main menu the menu option Wavelength Scan.
2. Insert the zero solution cell in the cell compartment and close the
cell compartment cover.
3. Press Zero.
"Zeroing" is shown below the graph as the baseline scan begins.
4. Insert the prepared analysis cell into the cell compartment and
close the cell compartment cover.
5. Press Read.
Under the graph, the display "Reading..." appears, and a graph of
the absorbance or transmission values for the scanned wavelengths
is continuously displayed.
English 24
The Wavelength Scan is complete, if
• the graph is shown full-size,
• the scaling of the x-axis occurs automatically,
• the Cursor functions in the vertical navigation bar are
highlighted.
• a sound is emitted
• To save the scan, press Options > Store symbol.

NOTICE
Remove all cells remaining in the instrument. Dispose of the cells or their
contents in an authorised manner.
Lamp replacement
DANGER
Risk of electric shock
Disconnect the instrument from the power source before the lamp replacement
procedure is commenced and until the lamp replacement procedure is complete.
CAUTION
Burn hazard.
Wait until the lamp cools down. Contact with the hot lamp can cause burns.
NOTICE
