6.2.3.2. Draught-Measurement
No flue gas probes with preliminary filter may be used for
draught measurements.
✓ A flue gas probe must be connected.
✓ The pressure socket of the instrument must be free
(depressurized, not closed).
Do not measure for longer than 5 min, as the drift of the
pressure sensor could have the effect that the readings are
outside the tolerance limits.
The
automatic pressure zeroing
(retrofit by Testo
Service) automatically zeroes the pressure sensor at
regular intervals (60s), to prevent the typical drift of the
pressure sensor.
