Make sure your spectrometers drivers are installed
properly. Once correctly installed the spectrometers
green light will illuminate. Please review the spectrometer
My custom software using the LabVIEW, C, C#, or VB
examples is not working
Make sure you are running the program as an administrator
(right click-> Run as administrator). Running as administrator
fixes 99% of all custom written software issues because
it allows programs unlimited access to read and write
to the C:\Program Files\StellarNet\SpectraWiz directory.

SpectraWiz and perform a reboot of USB driver using
the following steps.
Unplug power cord from unit
Unplug USB2EPP cable from unit
Unplug USB2EPP cable from computer
Plug USB2EPP cable into unit
Plug power supply into unit
Plug USB2EPP cable into compute
My GREEN-Wave spectrometer does not have a Green LED
and I cannot get it to work
Some GREEN-Wave models have obsolete electronics cards.

I cant find my calibration file
All modern StellarNet calibration files are shipped with
the spectrometer calibration data on a USB stick as an
executable self-extracting zip file. File names typically
start with MyCAL and are dropped in the SWCals folder
in the SpectraWiz directory.
If you have lost your calibration file we can replace
it for you.
I think my calibration is older than one year
f your calibration is older than one year, we recommend
that you call in and request to speak with an Applications
Scientist about a re-calibration service. Annual calibrations
are a good practice and healthy way to check up on your
spectrometer system health.
I saved my files in the SpectraWiz directory but I
can't seem to find them!
If you are not running SpectraWiz as an administrator
(depending on your operating system) your files may be
being saved to your virtual directory located C:\Users\YOU\AppData\Local\VirtualStore\Program

Is my Spectrometer calibrated for Irradiance measurements?
A USB stick is sent with all calibrated units. Check your
computer for a file called MyCal (with your units
serial number in the file name).
