- Column D: The elapsed time (in seconds) is calculated by multiplying the sampling
- Column E: The CO2 concentration in Column B is used as is.

5-3) Air Adjustment

Air Adjustment can be executed by placing the sensor in a clean air environment and clicking
[Calibration] button on the PC Application software.
After performing Air Adjustment, the display concentration will change to 400 ppm, which is same
as the default value. The default Air Adjustment setting value can be changed in 10ppm
increments.
Figure 12 shows example display concentrations when Air Adjustment is performed assuming that
CO concentration in ambient air is 420ppm.

When Air Adjustment is performed using CO
setting value to the known concentration.
concentration (in ppm) is recorded in order.
