CO Ambient
• 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 influences the accuracy of measurement. Frontal flow onto the sensor 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 fresh air (CO-free) during the zeroing phase.

Pipe Commissioning (EU regulation)
The pipe commissioning (using air or inert gas such as CO
2
or N
2
) is a tightness test for pipes, including fittings, but without gas appliances and the relevant regulating and safety devices. The pipe commissioning is performed after a load test has been successfully completed on newly laid gas pipes, or after renovation of existing gas pipes, and is used for the acceptance of these pipes.
It shows up even the smallest leaks in gas pipes.
According to DVGW TRGI 2008 and ÖVGW G10, the stabilization time and test time depend on the pipe volume.
- Pipe volume < 100 l: Adjustment time 10 min, test time 10 min.
- Pipe volume > 100 l to < 200 l: Adjustment time 30 min, test time
20 min.
- Pipe volume > 200 l: Adjustment time 60 min, test time 30 min.
