given answers for SpectraWiz / Stellarnet |
I have tried installing the SWdrivers.zip and SWdriver64.exe
files and I get the following error: 'PnPUtil.exe' is
not recognized as an internal or external command, operable
program or batch file.

I dont see a signal
- Verify
that your spectrometers green light is illuminated
- Check
to see you are not zoomed in on a localize portion
of the spectrum. Right click on the Y-axis to zoom
out & verify that you are looking at the entire
x-axis range of your spectro
- Right
click on the Dark Light Bulb on the top tab to release
any previously saved dark spectra
- Inspect
fiber optic cable to make sure it is not broken.
- Perform
a cable reset: Close SpectraWiz, disconnect your USB
cable, wait 15 seconds, plug back in your USB cable,
wait 15 seconds, launch SpectraWiz

The green LED on my spectrometer does not turn on and
I have no signal
Make sure your spectrometers drivers are installed
properly. Once correctly installed the spectrometers
green light will illuminate. Please review the spectrometer
driver
installation instructions |
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.

I get the error message USB device not present
and/or Scan Timeout.
- Check
to see if unit has power.
- Check
to see if the cables are listed in the Windows Device
Manager under USBDEV.
- Check
to see if USB2EPP cable is firmly inserted in back
of unit and USB port of computer.
- Close
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
Files\StellarNet\SpectraWiz |
I get the following error: I/O 32.
Delete the swref1 and swdark files from the SpectraWiz
directory. |
My unit is not displaying the correct wavelength range.
Ensure
coefficients and interface parameters have been entered
correctly.
Make sure spectrometer is not running off of computer
power (via USB cable).
Turn zoom off by left-clicking to the left of the y-axis.
Uncheck the Multiplexer option: Set-up è Spectrometer
channels è Fiber Optic Multiplexer. |
I get a Range Error when in Irradiance
mode.
- Back
away the unit from the light source (if possible).
- Install
a calibrated aperture.
- Decrease
the integration time
|
My measurements dont look right (using the
R400 reflectance probe).
- Insert
the end of the y-fiber with 6 fibers bundled into
the light source. Insert the other end into the spectrometer
(to get the most amount of light onto the sample).
- Block
any overhead lights from the probe.
- Make
sure the reference is not oversaturate
|
I get the following error Reference Oversaturated
at xxx nm.
- Decrease
the integration time.
- Back
the light source away from the unit (if possible)
|
Im having difficulty with my port settings.
We no longer support devices using parallel ports. Purchase
our USB2EPP cable to run the spectrometer from USB-1 or
USB-2 ports. |
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). |
