Note
If the probe has an overcoat, then the standards used in the calibration can be of a state of matter
different from the sample that you are using. You could switch between gas and liquid and your
calibration data will be valid. If the probe does not have an overcoat, standards used in the
calibration not only must be of the same state of matter as your sample, but also must have the
same refractive index as your sample.
Finalizing Calibration Using Factory Calibration
► Procedure
1. Click the green Curve Fit button. A graph displaying the results of your calibration procedure
appears in the bottom of the screen. Verify the results of the calibration, and then proceed to Step
2.
2. Click the green Update Channel Calibration button to save information from this calibration
procedure for the specified spectrometer channel into data files.
3. Save the calibration table for future use. Select File | Save Calibration Table from the menu bar.
• To print the entire screen, select File | Print from the menu bar.
4. Select File | Close from the menu bar to return to the main display window.
Calibrating Without Factory Calibration
Perform the steps below to calibrate the oxygen sensors for temperature compensation without using the
factory calibration.
Note
If you are using a factory calibration file, refer to Calibrating With Factory Calibration .
When calibrating for temperature compensation without using factory calibration, calibration becomes a
two-part task.
Preparing for Calibration without Using Factory Calibration – Part 1
► Procedure
1. Set the data acquisition parameters for the calibration procedure (integration time, averaging, and
boxcar smoothing).
