Subtract Dark
Selecting this box subtracts the current dark spectrum from the spectra being displayed. This command is
useful if you are trying to look at a change in an emission spectrum or are trying to eliminate from the
spectra fixed pattern noise caused by a very long integration period. The subtract dark spectrum function
only acts on spectra displayed in Scope Mode.
Acquire Data Modes
Chart Active
When
Spectrum & Kinetics
is chosen as the
Graph and chart display mode
in the
Spectrometer
Configuration
dialog box, the
Chart Active
function becomes visible in the display area above the
Scan button. This function is responsible only for the Kinetics chart. By
deselecting this function, users can use the scan button and collect data in just
the spectrum section of the graph. If the function is enabled, choosing the scan
button results in the collection of data in both the spectrum section of the graph
and the kinetics section of the graph.
Scan/Stop Button
When in
Single
mode, the Scan button acts as a snapshot. After selecting the
Single mode, click on the Scan button to take a scan. The button depresses and
Stop replaces Scan. The button will stay depressed until the scan has been completed (the time set in
the Integration Period box).
When in
Continuous
mode, the Scan button continuously takes scans. After each integration cycle,
another scan will immediately begin. The button depresses and Stop replaces Scan. Click on Stop to
halt the scanning process and discontinue acquiring data.
Scaling the Graph
You can change the vertical and/or horizontal scales of the graph by simply clicking on an X and Y
endpoint and manually typing in a value. The graph will then resize itself.
