Flue Gas, Flue Gas + M/S, Flue Gas + Dp2 - TESTO 340 Instruction Manual

G.2 Measurements
G.2.1 Flue gas, Flue gas + m/s, Flue gas + Δp2
The flue gas menus are the central measurement menus in which - in addition to the
readings measured with this function - the readings of all measurements carried out are
displayed (if this is selected in the
printed out from these menus.
The flue gas menus are always available, regardless of which sensors are connected.
Measuring functions of the three flue gas menus:
· The function enables flue gas to be measured.
Flue gas
· The
Flue gas + m/s
(+ air/mass flow calculation) by means of a Pitot tube (the connection cable for the
straight Pitot tube thermocouple should not be connected to the instrument probe
socket).·
· The Flue gas + Δp2
pressure measurement.
After measurements with high concentrations and longer measurements, the instru-
ment should be rinsed with fresh air in order to enable the sensors to regenerate, see
Chapter Recommended rinsing times, p. 57.
For flow speed measurement. Before beginning measurement, configure the location
settings (Pitot tube factor and correction factor), see chapter Location , p. 23.
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.
