Draught measurement

Call up function:
✓ A flue gas probe must be connected.
1. [ ] → Measurement options
Carrying out the measurement:
During the zeroing phase, the flue gas probe must be
outside the flue gas duct.
Do not measure for longer than 5 min, as a drift of the
pressure sensor means that the measured values may be
outside the tolerance limits.
1. Start measurement:
- Draught zeroing is carried out.
2. Position the flue gas probe in the hot spot (area of the highest
flue gas temperature).
The display showing the maximum measured flue gas
temperature (AT max) helps when positioning the probe.
- The measured value is displayed.
3. End measurement
