Basic safety information
Please read the following safety information carefully:
Avoid electricity:
Never use the instrument to measure on live parts!
Only use the mains unit supplied with the analyser for mains operation.
Damaged mains cables should only be replaced by authorised trained personnel.
Protect measuring cells:
Never store the instrument with solvents (e.g. acetone).
The pump should be switched off when emptying the condensate trap.
Only flue gas probes with an integrated condensate trap or
testo compact gas drier can be connected to the instrument.
Measuring correctly:
The complete measuring system (probe, condensate trap, hoses and connections) should be
checked for leaks prior to every measurement in order to eliminate incorrect measurements
caused by inleaked air.
Always ensure that the gas output in the instrument is free of obstacles so that sample gas can
escape unhindered.

arrow buttons you can scroll between the measured values windows (in the
measurement menu) or you can select a menu item in a list. If you have arrived at the last window/menu item you
will automatically return to the first window or the first menu item.
Via the print button
you can print the measurement shown on the display. The data is printed either on the
attachable printer or on the table printer depending on the preset printer type (see the Chapter on Printing the
measured results).
The analyser is switched on or off with the I/O button
. Before the final switch-off, the switch-off message
appears in the display. You can still prevent the analyser from being switched off by pressing any button except
. The analyser then returns to the measurement menu.
Via the
button, you can cancel selected processes or leave submenus. If you leave a submenu, by pressing
you can usually go back one menu window until you are in the main menu.
The selection and execution of the chosen function is confirmed by the Confirm button
from the measurement menu to the main menu simply press the
button.
The light for the display can be switched on and off via the light button

In the measurement menu 4 measured values per window are shown in the measured value/menu display range.
When the zoom function is used (via function button) only two measured values are shown but in a larger font.
The function toolbar describes the various function buttons. The assignment changes according to the menu. The
description of the function buttons in the display changes accordingly.
The arrows ( or
) left and right above the function toolbar indicate that there are additional functions in the
menu.
The operation display describes, with the help of graphics, the current analyser mode, e.g. indicates in which
menu you are, whether the analyser pump is operating and whether the instrument is mains operated. The symbols
are as follows:

⊂).
It is normal that the mains unit heats up. If temperatures are too high
(e.g. on account of an error in the analyser) the mains unit is protected
against overheating by a thermal protection switch.
Recharging the rechargeable battery
(only in ambient temperature range of between 5°C and 45°C)
Recharge the built-in battery prior to the first measurement or if the
instrument has not been operated for several days (see rechargeable
battery display during calibration phase).
In the case of extended periods of non-operation: recharge the
rechargeable battery every 4 weeks to avoid destructive total discharge and
the loss of memory contents.

Initial operation
Gas path switch function
(testo 300 XL only)
The gas path switch facilitates the complete separation of the CO cell from
the gas path. The CO cell is therefore protected from very high CO
concentrations. The remaining flue gas data can still be measured. This
gas path switch function is ideal in combination with the adjustable switch
off function of the pump at high concentrations
(see reference section
Service menu
Switch off limits).
O2/NO
The CO, NO and O2 cells are subjected to gas.
O2/CO/NO
For the calibration phase, the gas path switch must be at the
O2/CO/NO position i.e. the CO cell must be in the gas path. Otherwise
the CO cell will not be rinsed with fresh air and the values measured in
subsequent measurements will be false.
The CO cell is located outside the gas path.
Even if the CO cell is outside the gas path, low CO values can be shown in
the display. However these have no meaning.

The small but effective gas drier prevents damage due to condensate in
the analyser. This can occur especially in measurements on systems with
low flue gas temperatures (e.g. low temperature heating systems and
condensing furnaces). It is used instead of the condensate trap.
Preparation of the sample gas via the gas drier leads to a high level of
condensate precipitation. The condensate is collected in the housing and
is emptied by removing one of the end pieces.
If carrying out long-term measurements lasting several hours the use
of the automatic condensate emptying unit is necessary, i.e. the
compact gas drier 0632.3371.
Mains unit sockets for
connecting mains unit and
the power cable of the handheld analyser (can be

When using the compact gas drier you only have the option of one
mains unit (0554.0079) (see diagram below)

Example of measurement
Measuring the flue gas and
ambient air temperature
The flue gas temperature is measured via the thermocouple at the top of
the flue gas probe. The probe has openings in this area in the probe pipe
so that the thermocouple is protected but at the same time comes into
contact with flue gas.
In order to measure the exact flue gas temperature and therefore be able
to measure the exact flue gas loss, the thermocouple should always lie
in the flue gas flow. It should not be covered by the probe pipe frame.

The tip of the thermocouple should not touch the protection casing.
Bend back the tip of the thermocouple if necessary.

There are two ways of measuring the ambient air temperature with testo
300:
Initialising...
1. Measuring the ambient air temperature via the flue gas probe
AT

Accu :
Remain. time : 46 s
FUEL
LIST
DATE/T
The temperature is already being measured during the initialising phase
and is shown in the display.
The temperature measured by the flue gas probe is interpreted by the
testo 300 as the ambient air temperature and is saved as the ambient
air temperature value once the initialising phase is completed. All of the
dependent variables are calculated with this value.
Note AT! in the status line.
This type of ambient air temperature measurement is sufficient for
systems which are independent of ambient air.
During the initialising phase, ensure that the flue gas probe is held near
the burner´s intake duct.
2. Measuring the ambient air temperature via a separate ambient air
probe
The probe is connected to the additional probe socket at the side
connection panel of testo 300. As soon as a separate temperature
probe is inserted, the temperature is automatically used as the ambient
air temperature and is continuously measured.
13
Example of measurement
Measuring the flue gas and
ambient air temperature
Example:
A separate ambient air probe is not used during the initialising phase of
testo 300. A separate probe is connected during the measurement. The
value measured by this probe is used immediately as the ambient air
temperature.
The status display AT! disappears.
A separate ambient air temperature probe must be used in systems
which are independent of ambient air (ambient air is supplied, already
pre-heated, to the burner).
Special probes are available for this purpose:
a. Ambient air probe, 300 mm long ..................................0600.9791
b. Ambient air probe, 100 mm long ..................................0600.9797
The
c. Separate stub probe ....................................................0600.3692
can also be used for continuous measurement of the ambient air

Example of measurement
Draught measurement/Pressure measurement
The flue gas probe is used to measure draught. The draught can be
measured before or after a flue gas measurement.
The draught can only be measured if the pump is switched off.
However, the second pressure inlet must be open.
Do not switch between battery and mains operation when
measuring the draught (fluctuations in the voltage influence the
measured result)!
If the draught is measured following flue gas measurement
there will still be impact pressure in the hose, after the
pump is stopped, which first has to be lowered.
This happens within approx. 30 seconds.
Any remaining condensate in the flue gas probe must be removed
(shake probe with the tip nearest the ground).

Example of measurement
Differential pressure measurement (max. 80 mbar)
Do not use in the main pipe
Check for tightness between the sampling point and analyser
(outgoing gas and ambient oxygen could form an explosive mixture)!
No smoking when measuring,
no open flame!
Observe rated pressure of connection!
Do not exceed 80 mbar!
Gas cannot get into the analyser since a blanket of air forms between
the sensor and the gas inlet. For this reason the measuring unit is not
explosion-proof.

Ambient CO measurement
(testo 300 XL only)
For parallel measurement of the CO level in ambient air during a flue gas
measurement.
Note
Parallel or subsequent measurement of AT is not possible.
The probe should be connected before testo 300 XL is switched on.
The protective cap should be closed during the initialisation phase (otherwise
the measurements may be incorrect).
The protection cap should only be opened for the duration of the
measurement, close cap straight after measurement (mechanical protection of
sensor and adherence to accuracies).
Cigarette smoke influences the measurement (min. 50 ppm).
A smoker´s breath influences the measurement by approx. 5 ppm.
Initialising phase (60 s)
The CO probe is initialised together with the gas measuring cells
in the testo 300 XL analyser.
a. Open protective cap.
b. Hang probe, for example, in your shirt pocket.
The direction in which the gases flow onto the probe influences the
accuracy of the measurement. Optimum measured results are attained by
gently moving the probe back and forth. If the gases flow head-on onto the
sensor the values measured will be too high.
Measuring flue gas (START). The ambient CO value (in ppm only) is
measured parallel to the flue gas values. The ambient CO value is also
saved when the measured values are saved. Ambient CO can only be
measured if the pump is operating.
Close protective cap.
Warning if ambient CO value > 50 ppm CO

Example of measurement
Leak detection probe
(testo 300 XL only)
Do not use leak detection probe or testo 300 XL in closed rooms or
facilities in which gases have collected in an explosive mixture.
The use of other electrical instruments is prohibited.
It must be ensured that the concentration of gas does not
exceed 20% of explosive level.
Using the leak detection probe, even the smallest quantities of explosive
and combustible gases, and in particular natural gas and liquefied
petroleum gas (LPG), can be detected in the air. Suitable for detecting
leaks in pipelines, containers and instrument where gas flows.

Several measurements can be saved under one designator.
If the Memory function key is pressed repeatedly this enables the

4. Reading in a designator with a barcode pen
The barcode pen automatically assigns the measured data to a
measuring location.
If a barcode label is available on location you can read it in with the
barcode pen.
The barcode pen is inserted in the RS-232 socket at the side of the
analyser and be plugged in and out if the analyser is on. Attaching the
barcode pen with the holder to the SoftCase (item no. 0516.0501)
makes handling easier.
Activate the barcode pen by holding the tip of the pen on a white
surface e.g. the barcode label.
Then run the pen over the barcode strip. Correct transmission is
confirmed by a signal.
The designator is automatically added to the testo 300 XL designator list
and is selected as the active designator. You, therefore, do not need to
input the customer´s number beforehand via PC or by hand into the
testo 300 XL. If you have a customer whose number is not yet saved in
the analyser, you can read in the number to
testo 300 XL directly on location via the barcode. If a designator has
already been read into testo 300 XL only this is activated.

Data transmission
Data transmission to branch software
The measured values saved in testo 300 can be transmitted to your PC for
further processing using branch software.
In order to enable transmission of data from testo 300 and
the software specific to that particular branch a partnership must
exist between the respective software house and Testo.
Connection from testo 300 - PC
The testo 300 and PC must be connected in order to be able
to send measured data from testo 300 to the branch software.
Setting up the connection
1. When switched off, testo 300 is connected via the
analyser - PC cable (0554.0154) to the serial interface in the
PC (COM1 / COM2).
2. Switch on testo 300. It is not necessary to select a submenu to transmit the data. testo 300 is now ready to receive
and transmit data.
31
Reference section
Data transmission
3.
Start branch software.
- Select serial interface (COM1 / COM2)
- Transmit testo 300 to branch software
or
read in designator (e.g. customer number) from the branch
software to testo 300.
Adjusting the baud rate
BAUDRATE
The measured data is transmitted from testo 300 and the PC at a certain
speed known as the baud rate.
The baud rate in testo 300 can be adjusted (See Reference section
Service menu
Baud rate).
You will find the baud rate of your branch software in the software
Instruction manual.
The baud rate in the PC and testo 300 must be the same.
If the baud rates are different there will be no connection between

Drawing
screw
The condensate trap is designed in such a way that there is a certain
flow direction. This is marked with arrows on the housing section. If
gas flows in the opposite direction the condensate trap cannot
function properly and this could lead to the instrument breaking
down.
When assembling the condensate trap, ensure that the seal
rings are not damaged and that the filter tubules (A) do not get
mixed up.
Flue gas probe
Cleaning the flue gas probe
If there is a large amount of dust in the flue gas the gas path sections in
front of the pipe filter can become clogged or alloyed.
Cleaning the flue gas probe
if the gas paths become clogged
Remove the probe pipe and place in hot water. Blow air through pipe or
clean with a round brush (e.g. made of brass).
Changing a defective thermocouple
Pull out the bending protection spring from the guide at the back outlet
with a counterclockwise movement and pull out the tube to the left. Pull
out the thermocouple on the tube.
Only remove the thermocouple if it is defect. The thermocouple can
be damaged when pulled out of the connection tube.
Remove the bending protection spring and take the cable out of the slit
tube.
When inserting the new thermocouple do not press on the thermocouple
lead. Press it into place with the help of a small screwdriver.

T/C?
1. Temperature probe not connected.
2. Temperature probe is not connected correctly.
Flue gas temperature and its calculated values are not
measured, the remaining values are listed. Check the
temperature probe connection or insert new temperature
probe.
AT!
The temperature probe for separate ambient air
temperature measurement is defective or not available.
The last measured value is frozen. See page 12.
DT?
Admissible operating temperature is exceeded.
The ambient air changes to non-permissible values.
Adapt ambient air temperature.
O2!
Measurement of the zero point is not stable.
Cause: O2 cell was changed but the specified time of 60
min. for the cell to adapt was not adhered to.
Switch off analyser and wait for adaptation.
O2?
O2 cell is worn-out. Change measuring cell.
CO! / NO!/
Measurement of the zero point is not stable. Let the
initialising phase run several times.
CO?/ NO?
There is still flue gas in the analyser or very high
concentrations were measured or the initialising phase is
taking longer.
Cause: Insufficient air was rinsed through following the
last measurement or the probe is in the flue gas.
Probe should be brought into contact with fresh air. If
there is still no change after several runs of the initialising
mode the cell must be defect or the cell is worn-out.
VI?
The analyser supply voltage is too low. If the battery
voltage drops below 4.4 volt there is automatic switchoff. Recharge battery or connect to mains.
NO
or
CO
Measured value is greater than saved cutoff threshold.
Remove the flue gas probe from the flue gas pipe and
rinse the measuring cells with fresh air. Continue with the
measurement only if it is really necessary. Measured
cells may be damaged or destroyed!
In the case of CO the gas path switch in testo 300 XL
can be set to O2/NO and the measurement can be
continued.
Measured values >500 ppm CO were measured when
the ambient CO probe was used.
Danger of poisoning
Message disappears once the values measured fall
below <200 ppm CO.

Changing the battery
To put in/change batteries or rechargeable batteries, open the battery
compartment (at bottom of instrument). Use 4 x 1.4 V alkaline or corresponding
rechargeable batteries. Insert as shown in diagram. Close battery compartment.
Caution: A separate recharger, 0554.0110 (incl. 4 standard rechargeable
batteries) is required to recharge the batteries.
Changing the paper
The paper section is at the top of the printer. Open it and position the paper as
shown in the diagram opposite.
Caution: The paper is thermal paper which means that only one side can be
printed. Therefore ensure that the paper is inserted properly.
Move slide switch to “Line feed” position so that the paper can run through.
Then close the paper section again.
The printer is not powered via the hand-held instrument, therefore it must
always be switched on and off separately.
After approx. 8 min. the printer goes into a power save mode to save the
battery. Switch the printer off and then on again to reactivate it.
The attachable printer has a powerful bi-directional infrared interface with a data
buffer in the printer. Once the
button is pressed, the data is transferred in
the matter of seconds. The line of transmission should be kept free of obstacles
until the instrument has confirmed transmission.
60°
The line of transmission should run in a straight line between the analyser and
printer and should not be blocked by obstacles.
20°
10°
The distance between analyser and printer should not be more than 1m.
Note:
If printing large amounts of text
- more than 1 m text we recommend you to attach the printer to the analyser.
