Wavelength points and ratios can be set up.
Results will be grouped into a table format automatically.
Spectrum Processing Function
Trace a Spectrum
The cursor can be moved to a desired point in the spectrum displayed on the screen and
the photometric data at this point is displayed.
Automatic Peak Detection
After a scanning is complete, peaks and valleys can be automatically detected and listed
in a table format. They will also be labeled on the spectrum.
Scale Expansion
Simultaneous expansion of the X and Y axes are provided with the “Zoom” function.
Display range can also be changed though the “Display Setup” function.
Differentiation
You can calculate and display the first through to the fourth derivative spectrum for a given
spectrum. Derivative spectrum is useful for enhancing spectrum data that are not readily
apparent in an absorbance spectrum.
Calculate Spectrum
You can calculate addition, subtraction, multiplication and division between two spectrum
with the resulting data displayed on the screen.
System Check and Calibration Function
Instrument Validity Check
Up to 10 wavelength points can be set up in the instrument validity mode. Two methods
can be selected (Photometric Validity measurement and Wavelength Validity
measurement) and tolerance can be entered. Results will be grouped into a table format
automatically.
Dark Current Check
You can resample the dark current of the instrument.
Spectrum Bandwidth Check
A special scan for checking spectrum Bandwidth and it will calculate the spectrum
Bandwidth value automatically.
Energy of Light Sources Check
It allows scan the energy of light sources with a fixed gain (0-7).
Reset Wavelength
It affords to relocate the 656.1nm.
