When Vision has completed the test, the
tabulated results may be printed. They are also
stored in the Diagnostic Database for later
recall.
When the test is complete, click “Close
Window”.
The control chart view is shown at right. The top
row of tabs is for selection of wavelength range
for viewing, as described above. The middle row
of tabs selects the standard. The 2% reflectance
is shown in this illustration.
The bottom tabs select between tolerance limits
(defined by Metrohm NIRSystems) or control
limits that are calculated on the specific
instrument being tested. Normally the control
limits will give the best indication of
performance.
