TESTO 330-1 - Measurement Functions: Draught and BlmSchV; Draught Measurement; BlmSchV Measurement Sequences (Specific Models)

G.2.2 Draught
A flue gas probe must be connected.
The pressure socket of the instrument must be free (i.e. unpressurised, not closed).
Do not measure for longer than 5 min, as the drift of the pressure sensor means that
the readings could be outside the tolerance limits.

Measuring:
1
Start measuring: .
- Draught zeroing (5 s).
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 (FT) helps when
positioning the probe.
- The reading is displayed.
3
Stop measuring .
- The reading is recorded.
Optional:
To print the reading: .
4
Copy the reading to the
Flue gas menu: .
- The
Measurements menu is opened.
G.2.3 BImSchV (testo 330-3 / testo 330-2LL)
Two different prescribed measurement sequences can be performed in the BImSchV
menu: They are the BImSchV measurement sequence and the qA mean value measure-
ment sequence.
CO measurement can then be switched off.
In the qA mean value sequence, 3 successive flue gas loss measurements are taken
and the mean value is calculated from them.
In the BImSchV sequence, a draught measurement is performed first, then a flue gas
measurement. Regardless of the device settings, 8 readings are shown per display page
in a fixed order.
The readings are recorded in the
BImSchV menu and are not copied to the Flue gas menu!
A flue gas probe and a combustion air temperature probe must be connected.
