Specifications


Max ambient temperature to operate system: 110 degrees F
Max spectrometer case temperature: 30 degrees C
Max spectrometer case humidity: 90% RH

If spectrometer case humidity reaches this point, the silica packet inside
spectrometer case needs to be replaced.

Max side case (control box) temperature: 65 degrees C
Max aux case temperature: 65 degrees C

Field Files

Description

acquisition_samples_*.txt

Transformed samples in absorbance
taken during acquisition.


Figure 1

The first column represents the sample number, except for the first value of

–4, which

indicates that the row is the spectrometer wavelength values. There will be a total of
384 wavelength values, which also represents the number of columns in each sample
file. In this example a total of three samples were taken, for each wavelength there is
an absorbance value, so for sample 1 at wavelength 348.84732 the absorbance was
.8793300.

master_veris_standards.txt

External reference data in reflectance
standardized against Avian grayscales.
(provided by Veris)


external_reference_*.txt

Untransformed external reference data
in reflectance taken during system
check.


xform_*.txt

Transform created by comparing
master_veris_standards and latest
xternal_reference files.


raw_spectra_*.bytestream

Field data taken in compact bytestream
format. Note: Each time system check

is ran a new .bytestream file and

xform.txt file will be created. Once

system check has been completed
