A flue gas probe must be connected.
CO ambient measurement cannot be done with the external
CO ambient probe.
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 measurement. Frontal flow onto the probe
leads to higher measured values. 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 fresh air (CO-free) during the
zeroing phase!
