External
Reference buttons
Failure light
Number of times
each reference
has been ran,
since system
check was
opened.
Manually stores
dark/reference
data. This should
be done if there is
a failed reference
check. This could
be caused by the
shank steps not
being within
specification, or
one of the
spectrometers is
not running. Try to
clear out the
reference by
pressing F2. If
problem persists
shut down system
and restart.
.
Auxiliary data can be scrolled through by the up and
down arrows on the left of the indicator. Data
corresponds to chart listed on the right of indicator.
Note: a reading of
–1.50 indicates failure of that
component or communication problem. See
Glossary for Auxiliary data information table.
Ref check graph:
This should be close to
a straight line except
for the edges and the
center. The reference
check light will indicate
if this is an acceptable
reference check.
Root mean squared
error of current
external reference.
By default the RMSE
should be within .10
for references 1,2,& 4
and within .15 for
reference 3.
Reference check light is
green for good references
and red for a failed
reference. If a reference
fails, press F2 to store a
new dark and reference.
Ref check light
Graph that compares current
external reference to master
reference. These should
correlate to one another if
system check has been
completed before.
A yellow ER light
indicates possible
problem. Regard as a
good reference unless
transform step fails.
Shank steps should
be 5.2 cm within +-
.03 cm.
If steps are
not within this range
then press F2 to
store another
dark/ref.
