3.1. Use
The testo 320 is a handheld measuring device for the professional
flue gas analysis of combustion plants:
• Small combustion plants (burning oil, gas, wood, coal)
• Low-temperature and condensing boilers
• Gas water heaters
These systems can be adjusted using the testo 320 and checked
for compliance with the applicable limit values.
The following tasks can also be carried out with the testo 320:
• Regulating the O2, CO and CO2 values in combustion plants
for the purpose of ensuring optimal operation.
• Draught measurement.
• Measuring and regulating the gas flow pressure in gas water
heaters.
• Measuring and optimising the flow and return temperatures of
heating systems.
• Ambient CO measurement (only possible with additional
ambient CO probe 0632 3331).
• Ambient CO measurement (only possible with additional
ambient CO probe 0632 1240).
• Detection of CH4 (methane) and C3H8 (propane) (only possible
with additional gas leak probe 0632 3370).
The Bluetooth

If the mains unit is connected, the measuring instrument is
automatically powered from the unit.
1. Connect the mains unit instrument plug to the instrument's
micro USB socket.
5.2.2. Connecting probes
2. Connect the mains plug of the mains unit to a mains socket.
Probe detection at the flue gas socket is carried out
continuously. New probes are recognised automatically.
Connect a probe to the probe socket before switching on
the measuring instrument or start sensor detection
manually after changing the probe: [Options] → Sensor
detection.
24
Connecting flue gas probes/gas pressure
adapters/temperature adapters
> Insert the connector plug into the flue gas socket and lock by
slightly turning it clockwise (bayonet lock).
There must be no more than one extension lead (0554
1201) between measuring instrument and flue gas probe.

5.2.7. Saving data to the clipboard (temporary memory)
Using the clipboard, measurement results from various
measurement types can be combined to produce a common
record, which can then be printed out (see above). Data is saved to
the clipboard via the Options menu and the Clipboard command.
If there is data in the clipboard, the status bar shows the symbol .
If there is data in the clipboard and the Print command is triggered,
all data in the clipboard will be printed out.
5.2.8. Confirming an error message
If an error occurs, an error message is shown on the display.
> Confirming an error message: [OK].
Errors that have occurred but have not yet been rectified are
indicated by a warning symbol ( ) in the header.
Error messages that have not yet been cancelled can be displayed
in the Error diagnosis menu, see Instrument diagnosis, page 31.
5.2.9. Switching off
Unsaved measured values are lost if the flue gas analyser
is switched off.
> Press [].
- The pump may start and the sensors may be rinsed until the
switch-off thresholds (O2 > 20%, other measurement
parameters < 50 ppm) are reached. The maximum rinsing
period is 3 minutes.
- The measuring instrument switches off.
5.3. Address/Location
All measuring values can be saved under the currently active
location. Measuring values that have not been saved are lost when
the measuring instrument is switched off!

The First steps chapter (see First steps, page 24) must
have been read.
6.2.1.1. Testing for leaks
The entire measurement system (probe, condensate trap, hoses
and connections) must be tested for leaks before each
measurement to avoid incorrect measurements due to the
infiltration of external air. Testing is carried out while the pump is
running and may be performed by attaching a compressed balloon
pump. The measurement system is leak-tight if the balloon pump is
not filled with air.
6 Using the product
6.2.1.2. Zeroing phases
Measuring the combustion air temperature
If no combustion air temperature probe is connected, during the
zeroing phase, the measured temperature of the flue gas probe is
41
taken as the combustion air temperature.
The flue gas probe should not be in the flue gas duct during
the zeroing phase.
All dependent parameters are calculated using this value. This
method of measuring combustion air temperature is sufficient for
systems dependent on ambient air.
If a temperature probe is connected, the combustion air
temperature is measured continuously via this probe.
Page 42
6 Using the product
Gas zeroing
When the instrument is switched on, the measurement menu is
opened and the gas sensors are zeroed.
The flue gas probe must be in fresh air during the zeroing
phase!
Draught/pressure zeroing
The pressure sensors are zeroed when a pressure measuring
function is called up.
The flue gas probe must be in the fresh air during the
zeroing phase / the instrument must not be pressurised
during zeroing.
6.2.1.3. Using the modular flue gas probe
Checking the thermocouple
The thermocouple of the flue gas probe must not lie against the
probe cage.
> Check before use. Bend the thermocouple back if necessary.
Aligning the flue gas probe
The flue gas must be able to flow freely past the thermocouple.
> Align the probe by turning it as required.
42
Page 43
The tip of the probe must be in the centre of the flue gas flow.
> Align the flue gas probe in the flue gas duct so that the tip is in
the core current (area of the highest flue gas temperature).
6.2.1.4. Measurement view
Only those parameters and units that are enabled in the measured
value display appear in the measured value display, in the saved
measurement records and on the record printouts.
> Before carrying out measurements, set up the measured value
display in such a way that the required parameters and units
are enabled, see Measurement view, page 32.
6.2.1.5. Setting the location and fuel

6.2.14. Ambient CO
This function is not available when the Spain country version is
selected.
✓ An ambient CO probe (recommended) or a flue gas probe must
be connected.
Cigarette smoke influences the measurement by more than
50 ppm. The breath of a smoker influences the
measurement by about 5 ppm.
When using an ambient CO probe, note that:
The direction of flow of the gas has an effect on the
accuracy of measurement. Frontal flow onto the probe
leads to higher measured values. The best measurement
results are achieved when the probe is moved gently
backwards and forwards.
When using the ambient CO probe and the flue gas probe,
note that:
the probe must be in the fresh air (CO-free) during the
zeroing phase!
