When finished, this box is shown with the final
correction spectrum. The correction is downloaded to
the instrument for the proper channel, and will be
applied whenever a “Reference Standardized” DCM is
used.
Note that the DCM must be created with “Reference
Standardization” checked in the “Project Options”
box. If the DCM was created prior to selection of
“Reference Standardization”, then it was checked, the
DCM will not apply Reference Standardization.
Click “Print Report” to print the corrected spectrum.
Select “landscape mode”. Click “Close Report” to
continue.
Typically the user will complete a full set of tests on
one multiplexer channel before proceeding to the
next. If this is the case, proceed to Instrument
Calibration.
It is helpful to keep a checklist of what tests were
performed on each channel, to be sure no tests are
omitted.
If proceeding to Reference Standardization on the
next channel, it must be selected. From the menu bar,
click on Acquire, then Select Channel. Use the spinner
to select the correct channel, then click on “OK”.
This must be performed for each channel. Always
verify the channel before proceeding with the test.
Note that cleanliness of the probe window is very important when this program is run. If the window
is not extremely clean, the character of the window contamination will be imparted to the reference
correction. Therefore, maintain a clean window at all times.
