1. Click on “Analyzer PRO Setup/Diagnostic”, then “Run
Performance Test”.
2. Vision displays the Instrument
Configuration box. This information is used
to set up the Diagnostic Database entries
for this instrument.
If correct, click on “OK”.
This box is shown upon each initial
connection, and is not shown on
subsequent diagnostic tests, as long as the
instrument has remained connected to
Vision.
3. Vision asks which fiber should be used for the test.
The test defaults to the Sample fiber. (Do not click
yet.)
Be sure Reflectance probe – the one used for
calibration – is on the fiber, and the reflectance
standard is in place as shown in the photo.
This shows the correct placement of the reflectance reference on the
probe.
NOTE: the label may be on the top plate, instead of on the side.
Let gravity hold the reference in place – do not apply pressure, as this
could compress the reference material and change its reflectivity.
As a precaution, always keep the probe window and the reflectance
reference very clean. Do not allow dust, dirt, or liquids to contaminate
the surface. Consistent spectral performance depends upon clean
surfaces.
4. Click on “Sample” to start the test.
