3.2. Getting to know the product
3.2.1. Connecting probes / sensors
Sensor detection takes place during the activation
process: Sensors that are required must always be
connected before the flue gas analyser is switched on,
or the flue gas analyser must be switched off and then
on again after a sensor change, so that the correct
sensor data can be read.
> Connect the required probes / sensors to the corresponding
ports.
3.2.2. Connecting system components
3.2.2.1. Connection using contact strip
The Control Unit can be plugged on and locked to the meas. box.
1.Place the guide groove in the bottom side of the Control Unit

Unit can also be inserted with the back facing up, however,
in this case there is no connection to the meas. box.
3.2.2.2. Connecting via Data bus cable (accessory)
The individual components (e.g. Control Unit with meas. box or
meas. box with meas. box) can be connected using the Testo
databus cable.
> Connect the Data bus cable to the Data bus interfaces.

3 First steps
14
Please observe the following points when setting up a connection
via databus cable:
• Use only Testo databus cables
• Do not route databus cables in the vicinity of electric power
cables.
• Ensure sufficient power supply by supplying each meas. box
with mains voltage.
• The cables should ideally be plugged in before the system is
switched on. Connecting during operation (hot plugging) is
possible, however, depending on the combination the system
may need to be switched off and on again.
• The connection cannot be separated under load.
• Data bus subscribers: max. 16 meas. boxes in one Data bus
system.
• Cable length: max. 50m between Control Unit and meas. box,
max. 800m between all meas. boxes in the databus system.
• Each component in the Data bus system must have an
unambiguous bus address.
• The bus system must have a defined electrical termination, see
below.
Electrical termination of the bus system
The databus system is linear in structure. The Control Unit or the
Testo databus controller with USB connection represents the
beginning of the line.
The end is represented by the last components connected in the
system (meas. box or analog output box). This component must
have a defined electrical termination.
An analog output box is the furthest subscriber.
> Insert the Data bus termination plug into the Data bus socket on
the analog output box.
A meas. box is the furthest subscriber.
> Set the Data bus termination slide switch in the meas. box to
switch position right ( ).

Parameter Description
Pitot Tube
Factor
The parameter "Pitot tube factor" influences the
measurement of flow speed, volume flow rate and
mass flow. The Pitot factor depends on the type of
Pitot tube used:
Straight Pitot tubes: Factor = 0.67
Prandt’l Pitor tubes (bent): Factor = 1
Humidity The parameter "Humidity" (combustion air humidity)
influences the calculation of qA (flue gas loss) and
flue gas dew point. The factory setting is 80.0%
humidity. To achieve a higher accuracy, the values
can be adjusted to the actual ambient conditions.
Pressure
absolute
The absolute pressure influences the calculation of
flow speed, volume flow, mass flow and flue gas
dew point. The factory setting is 980mbar. To
achieve a higher accuracy, the values can be
adjusted to the actual ambient conditions.
If a CO2-(IR) module is installed, the
absolute pressure value measured there will
automatically be used.
Barometric
pressure
The input of the barometric pressure and the
height above sea level is only required when
no absolute pressure is available (no CO2IR
module present).
The barometric pressure influences the calculation
of flow speed, volume flow, mass flow and flue gas
dew point. To achieve a higher accuracy, the values
can be adjusted to the actual ambient conditions.
This is 1013mbar as an annual average, regardless
of the altitude. Depending on the current weather,
this pressure can fluctuate by ±20mbar around the
annual average.
Altitude The height above sea level influences the
calculation of flow speed, volume flow, mass flow
and flue gas dew point. To achieve a higher
accuracy, the value can be adjusted to the actual
ambient conditions.
