Field Auxiliary output definitions
EC_Sh

– Electrical conductivity shallow.

EC_Dp - Electrical conductivity deep.
Temp

– Soil temperature

Spec_T

– Spectrometer case temperature

Ctrl_T

– Control box temperature (this is the metal box on the side of the spectrometer

case)
Spec_H

– Spectrometer case humidity

Aux_Te

– Auxiliary case temperature

Aux_Hu

– Auxiliary case humidity


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
Max aux case humidity: 90% RH

Description

acquisition_samples_*.txt

Transformed samples in absorbance
taken during acquisition.


Figure 22

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.
