Finalizing Calibration without Using Factory Calibration – Part 1
► 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.
Preparing for Calibration without Using Factory Calibration – Part 2
► Procedure
1. Select Calibrate | Oxygen, Single Temperature from the menu bar. The Single Temperature
Calibration screen appears.
2. Enter the serial number of the probe in the S/N box. The Date box should display the current
date. The file name and path will appear under Calibration File Path once you select File | Save
Calibration Chart and save the chart. At the bottom of the screen is a box to assign a text label
to the Oxygen Concentration Units.
3. Select Single Point from the drop-down menu located next to Calibration Type.
Note
Single Point calibration is based on the procedure you just completed in the Oxygen, Multiple
Temperature dialog box. Because you are using the data from the Oxygen, Multiple Temperature
dialog box, you only need one standard of known oxygen concentration to complete your
calibration.
4. Locate the Channel section and select the spectrometer channel associated with the sensor you
are calibrating.
5. Select the algorithm type from the Curve Fitting drop-down menu. This algorithm will be used
to calibrate your sensor system. See Calibration Requirements for Oxygen Sensors for more
information on algorithms.
