the wavelength. The data associated with each data point can
also be shown as a table.

Option Description
More Further options are displayed
Folder icon To store the scan data
Reference Off/On
From the displayed list of stored scans, a record is selected for use as a reference
scan/superimposed scan. This can be highlighted or shown in the background in comparison
with the actual measured scan.
Note: This option is only available when there are stored scans with the same wavelength range
and step.
λ Enter the wavelength spectrum and scan interval
Timer icon
This functions as a stopwatch. It helps to make sure that the steps of an analysis are correctly
timed (e. g. reaction times, wait times, etc., can be exactly specified). When the specified time
has elapsed, a sound is emitted. The use of the timer has no influence on the reading program.
View
Table/Graph
Enables the switching between the display of tabular scan data (wavelength/absorbance) and
the graphical representation of the curve.
Note: "View Table" is activated after the first measurement.
Cursor Mode
To select Track or Peak/Valley. The selection for this menu option determines to which points
on the graph the cursor moves.
Send Data To send data to a printer, computer or USB memory stick (Type A)
Integral: On/Off The integral gives the area and the derivative of the integral gives the original function
Scale & Units
Scale: In the automatic scaling mode, the y-axis is automatically adapted so that the total scan
is shown.
The manual Scaling mode allows sections of the scan to be displayed.
Units: Choice of absorbance or transmittance.
Reading Mode
Single Reading: One measurement result is shown after tapping on Read.
Carousel 1 inch square: Optional measurement of carousel insert with up to 5 square cells.
Carousel 1 cm square: Optional measurement of carousel insert with up to 7 square cells.
Recall measurement
