Step 3 Open the pull down menu Control -> Adjust Configuration [Alt+C,C] in
the RS
3
application.
Step 4 Set the white reference number of scans to 30, and dark current averages to 60
scans.
Step 5 Set the spectrum average (or sample count) to 30 for indoor or artificial
illumination.
Note: The actual spectrum average will be determined by striking a compromise
between noise reduction through averaging the spectra and the time desired
for each spectrum collection. For instance, if you are using the instrument in
the field, are walking a large area, and are making frequent spectral readings,
you will want a shorter average setting than if you are collecting spectra
in-situ and desire the cleanest spectra possible.
Step 6 Optimize the instrument to the Spectralon.
Spectralon is an example of a reference standard to take a white reference
against. (Labsphere, Inc., Shaker St., PO Box 70, North Sutton, NH
03260-0070, PH: 603-927-4266, FX: 603-927-4694, E-mail:
sales@labsphere.com, Website: www.labsphere.com). Spectralon is also
available from ASD.
Step 7 Take a White Reference (or baseline reference).
Step 8 Observe samples.
6.3.2 Indico Application
Step 1 Follow the instructions for plugging in the instrument and starting the Indico
software.
Step 2 Attach an appropriate accessory. Remember that the TerraSpec spectrometer
requires an external (artificial) light source.
Step 3 Open a new project either by selecting File->New Project from the
pull-down menu.
Step 4 Type in a name for this project and click on the OK button.
Step 5 Select Spectrum->Sample Count/Average from the pull-down menu.
Step 6 Set the Instrument Sample Count to 30 for indoor or artificial
illumination.
Note: The actual spectrum average will be determined by striking a
compromise between noise reduction through averaging the spectra
and the time desired for each spectrum collection. For instance, if you
are using the instrument in the field, are walking a large area, and are
making frequent spectral readings, you will want a shorter average
setting than if you are collecting spectra in-situ and desire the cleanest
spectra possible.
