CO ambient

✓ An ambient CO probe (recommended) or a flue gas probe must
be connected.
Cigarette smoke influences the measurement by more than
50 ppm. The breath of a smoker influences the
measurement by about 5 ppm.
When using an ambient CO probe, note that:
The direction of flow of the gas has an effect on the
accuracy of the measurement. Frontal flow onto the probe
leads to higher readings. The best measurement results are
achieved when the probe is moved gently backwards and
forwards.
When using the ambient CO probe and the flue gas probe,
note that:
The probe must be in the open air (CO-free) during the
zeroing phase!
