If the Draught measurement parameter is enabled in the reading
display, a draught measurement is automatically started in parallel to
the flue gas measurement. In the List measurement data view, the
parallel draught measurement can be stopped/restarted. This draught
measurement is performed separately to a measurement of the
Draught measurement type.
For the draught measurement, the minus connection for differential
pressure measurement must be free (ambient pressure, not closed).
