For fl ow speed, air fl ow and mass fl ow to be measured correctly, the shape and surface
area of the cross-section must be set.
The parameters
Pitot factor and Offset factor infl uence the measurement of fl ow speed, air
fl ow and mass fl ow. The Pitot factor is dependent on the Pitot tube used:
· Straight Pitot tubes (0635 2041, 0635 2042): Pitot factor 0.67
· Prandtl (curved) Pitot tubes (0635 2145, 0635 2345): Pitot factor 1.00
The correction factor refers to the stated areas. If part of the area is covered (e.g. by gril-
le bars), this can be compensated via the correction factor. The free portion of the area
should be given (e.g.. 20% covered and 80% free: correction factor 0.8). The correction
factor should be set at 1.00 for all standard applications.

Setting sensor protection:
To extend the measuring range and protect the sensors against overloads, you can set
thresholds which, when exceeded, activate sensor protection. Thresholds for a variety
of parameters can be set, depending on the sensors that are connected.
For instruments without „Dilution of all sensors“ option: If a threshold of the sensor in
slot 2 is exceeded, the gas to sensor 2 is diluted by a factor of fi ve.
There is switch-off if a sensor threshold value is exceeded in slot 3 or slot 4.
For devices with the „Dilute all sensors“ option: If a sensor threshold value is exceeded in slot 2, the gas to sensor 2 is diluted by factor fi ve. If a sensor threshold value is
exceeded in slot 3 or slot 4, gas to all sensors is diluted by factor two.
With dilution active, the reading resolution and accuracies will change, see Technical
data. Diluted values are represented inversely.
If the threshold is still exceeded despite dilution, the instrument is switched off. To de activate sensor protection, set the thresholds to 0 ppm.

Measurement CO (H2-compensated) sensor:
In order to protect the sensor and for a longer sensor life, we recommend that in
measurements with unexpectedly high CO concentrations (more than 1,000ppm),
the CO sensor is installed in slot 2, and that the threshold of the CO sensor protection is set to 1,000ppm. From a CO concnetration of 1,000ppm, dilution with a factor
of 5 is automatically activated.
This setting can also be made if H2 concentrations of more than 1,000ppm are to be
expected.

Dangerous gases
Danger of poisoning!
Observe safety regulations/accident prevention regulations when handling
test gases.
Use test gases in well ventilated rooms only.
Recalibration with low gas concentrations can lead to deviations in accuracy in the
upper measuring ranges.
Sensor protection is deactivated during recalibration. For this reason, test gas concentration should be lower than the maximum value of the sensors.
Recalibrating the sensor at slot 2 has an effect on the dilution:Always carry out a
recalibration of measurement parameters before a recalibration of dilution.
The following conditions must be met when recalibrating:
· Use absorption-free tube material
· Switch the measuring instrument on at least 20 min before recalibration (warming-up)
· Use clean air for gas zeroing
· Charge the test gas via calibration adapter (0554 1205, recommended) or the tip of
the probe
· Maximum overpressure of the test gas: 30 hPa (recommended: unpressurised via
bypass)
· Charge the test gas for at least 3 min
Recommended test gas concentrations and compositions are given in Testo‘s fi eld
guide to test gases.

G. Measuring
This chapter describes the measuring tasks that can be carried out with the product.
Familiarity with the contents of the chapter Operation (see p. 15) is assumed.
G.1 Preparing measurements
G.1.1 Zeroing phases
Measuring the ambient air temperature (AT)
If no ambient air temperature sensor is connected, the temperature measured by the
thermocouple of the fl ue gas probe during the zeroing phase is used as the ambient
air temperature. All dependent parameters are calculated by this value. This method
of measuring ambient air temperature is suffi cient for systems dependent on ambient
air. However, the fl ue gas probe must be near the intake duct of the burner during the
zeroing phase!
If an ambient air temperature sensor is connected, the ambient air temperature is
measured continuously via this sensor.
Gas zeroing
The fi rst time a gas measuring function is called up after the instrument has been swit-
ched on, the sensors are zeroed.
The fl ue gas probe may already be in the fl ue gas duct during zeroing if a separate
AT sensor is connected.
Draught/pressure zeroing
The pressure sensors are zeroed when a pressure measuring function is called up.
The pressure sockets of the instrument must be free (i.e. unpressurized, not closed)
during zeroing.
36
1.800.561.8187 info@Testo-Direct.ca
www.Testo-Direct.ca
Page 37
G.1.2 Using the modular fl ue gas probe
Checking the thermocouple
The thermocouple of the fl ue gas probe must not lie
against the probe cage.
Check before use. Bend the thermocouple back if
necessary.
Aligning the fl ue gas probe
The fl ue gas must be able to fl ow freely past the
thermo couple.
Align the probe by turning it as required.
RGS
The tip of the probe must be in the centre of the fl ue
gas fl ow.
Align the fl ue gas probe in the fl ue gas duct so that
the tip is in the centre of the fl ow (area of the
highest fl ue gas temperature).
G.1.3 Confi guring the reading display
Only those parameters and units which are activated in the reading display appear in the
reading display, the saved measurement protocols and the protocol printouts.
Before beginning measurements, confi gure the reading display so that the required
parameters and units are activated, see Display edit, p. 27.
G.1.4 Set location/fuel
Before carrying out measurements, the measurement location and the fuel must be correctly selected see Memory, p. 22 and Fuels, p. 35.

G.2 Measurements
G.2.1 Flue gas, Flue gas + m/s, Flue gas + p2
The fl ue 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
Display edit menu). All readings can also be saved in or
printed out from these menus.
The fl ue gas menus are always available, regardless of which sensors are connected.
Measuring functions of the three fl ue gas menus:
· The
Flue gas function enables fl ue gas to be measured.
· The
Flue gas + m/s function enables fl ue gas to be measured in addition to fl ow speed
(+ air/mass fl ow 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 + p2 function enables fl ue gas to be measured in addition to differential
pressure measurement.
After measurements with high concentrations and longer measurements, the instrument should be rinsed with fresh air in order to enable the sensors to regenerate, see
Chapter Recommended rinsing times, p. 57.
For fl ow speed measurement. Before beginning measurement, confi gure 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.

Conversion from ppm to mg/scm:
The numerical factor used in the formula (e.g. 1.25 for CO) corresponds to the standard density of the respective gas in mg/m³. Please note:
- for SO2, standard density values in the range from 2.86 to 2.93 are stated in literature (difference between ideal and real gas behaviour for SO2)
- for NOx the standard density of NO2 (2.05), is used, as only this compound is stable (NO combines very quickly after its creation with oxygen to form NO2)
