Glossary
Spectrophotometer – A complete system for making spectral measurements. The
system includes a light source, means for collecting light that has interacted with the
material under test, and a spectrometer to measure the collected light.
Spectrometer
– Instrument to measure the quantity of light over a spectrum of
wavelengths. The spectrometer is the "measurement engine" of the spectrophotometer.
Auxiliary Data

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)
