9. Begin the flow of the process gas. The analog output reading will
drop as the oxygen sensor adjusts to the reduced oxygen level. During this time, reset the range as required.
10. For improved accuracy in the ppm oxygen ranges, a span gas calibration should now be performed (see “Span Gas Calibration” on page 19).
IMPORTANT: Sensor life is dependent on the application. High oxygen
concentrations and contaminants such as acidic gases will shorten the sensor life.

3.3.3 Air Calibration

An air calibration is always recommended upon installation of a new oxygen sensor. However, because of the non-linearity of the oxygen sensor, a span gas calibration (see the next section) can also be performed to ensure a faster and more accurate calibration for the ppm ranges.
CAUTION! The useful life of ppm sensors is extended by
minimizing exposure of the sensor to air.
To perform an air calibration, complete the following steps:
1. Press the
2. Press the
3. Press the
Enter key to enter the Main Menu.
Enter key to enter the Calibration menu.
Enter key to select the Air menu option.
4. Proceed to the appropriate section, depending on whether you
are calibrating a new sensor or recalibrating an existing sensor.
