Operation of the testo 300 is organised such that you can always recognise the button functions in the display.

The keyboardThe function buttons enable you to quickly change instrument functions and to completely control themeasurement. The function behind the function buttons are shown in the function toolbar. Not all of the functionbuttons in every menu have been assigned. Arrows ( or ) left or right above the function toolbar indicate thatthere are additional functions in the menu. These additional functions are displayed by pressing the left arrow button or right arrow button andare activated via the function buttons.

With the up /down arrow buttons you can scroll between the measured values windows (in themeasurement menu) or you can select a menu item in a list. If you have arrived at the last window/menu item youwill 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 theattachable printer or on the table printer depending on the preset printer type (see the Chapter on Printing themeasured results).

The analyser is switched on or off with the I/O button . Before the final switch-off, the switch-off messageappears 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 pressingyou 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 . If you wish to gofrom 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 or the automatic time function isstarted (See Settings, “Light” Chapter) .

The displayAll of the important information is shown constantly in the display.

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. Thedescription 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 themenu.The operation display describes, with the help of graphics, the current analyser mode, e.g. indicates in whichmenu you are, whether the analyser pump is operating and whether the instrument is mains operated. The symbolsare as follows:

Measurement menu ⊂ Mains operation Main menu

Fuel selection ⊃ ⊂ Service menu

Memory menu ↵ Input/Settings

Pump is operating

You can always see which memory place has been selected and which is active in the memory display box. Thenumber of measurements already saved under this memory place name is shown along with a serial number. If amemory place has not been selected “Noname” appears in the display.Error messages appear in the status display on the left. The measured value window in which you are located isindicated in the measurement menu e.g. 2/5 means that you are on page 2 out of a possible 5.

Testo rechargeable battery- The Testo rechargeable battery is recognised by the analyser and is optimally

recharged. The analyser can remain connected to the mains if the rechargeablebattery is full. Compensation charge follows.1) Display for battery level during the initialising phase or2) Query “Operation values” menu

Battery lifetime (with fully recharged battery): approx. 4 hours (depending onuse of display light)Standard rechargeable batteries or batteries- As an alternative to the Testo rechargeable battery, the standard rechargeable

battery (1.5V IEC KR 15/51) corresponding to type AA or battery type (1.5VMIGNON Alkaline IEC LR6 •AA• ) can be used.

- Standard rechargeable batteries cannot be recharged in testo 300. Anexternal recharger must be used.

- No display of the rechargeable battery level in the initialising phase. Voltagelevels can be called up in the “Operation values” menu.

Testo mains unit (0554.0054)- Ensure that the contact in the testo 300 connection plug is good ( ⊂).- The rechargeable battery or battery must be in the analyser.- Mains operation with empty rechargeable batteries possible.

Recharging the rechargeable battery (only in ambient temperature range of between 5°C and 45°C)

b. Standard rechargeable batteries or batteries: Recharging in the analyser isnot possible. Recharge via external recharger.

Since the NO measuring cell (if present) is constantly supplied with voltagefrom the rechargeable battery inside the analyser the rechargeable battery

must be regularly recharged.

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.

The display for the rechargeable battery may drop to 1/2 or 2/3 after beingswitched on or after a brief operating time caused by the characteristics

of the battery or the starting current. However, this does not affect thelife of the rechargeable battery.

The gas path switch facilitates the complete separation of the CO cell fromthe gas path. The CO cell is therefore protected from very high COconcentrations. The remaining flue gas data can still be measured. Thisgas path switch function is ideal in combination with the adjustable switchoff function of the pump at high concentrations(see reference section Service menu Switch off limits).

The CO, NO and O2 cells are subjected to gas.

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 inthe display. However these have no meaning.

Initial operationGas path switch function(testo 300 XL only)

Compact gas drier (optional) The small but effective gas drier prevents damage due to condensate inthe analyser. This can occur especially in measurements on systems withlow flue gas temperatures (e.g. low temperature heating systems andcondensing furnaces). It is used instead of the condensate trap.Preparation of the sample gas via the gas drier leads to a high level ofcondensate precipitation. The condensate is collected in the housing andis emptied by removing one of the end pieces.

If carrying out long-term measurements lasting several hours the useof the automatic condensate emptying unit is necessary, i.e. thecompact gas drier 0632.3371.

When using the compact gas drier you only have the option of onemains unit (0554.0079) (see diagram below)Mains unit sockets for

connecting mains unit andthe power cable of the hand-held analyser (can beplugged in as required)

For the calibration phase, the gas path switch must be at theO2/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 insubsequent measurements will be false.

The flue gas temperature is measured via the thermocouple at the top ofthe flue gas probe. The probe has openings in this area in the probe pipeso that the thermocouple is protected but at the same time comes intocontact with flue gas.

There are two ways of measuring the ambient air temperature with testo300:

1. Measuring the ambient air temperature via the flue gas probe

The temperature is already being measured during the initialising phaseand is shown in the display.The temperature measured by the flue gas probe is interpreted by thetesto 300 as the ambient air temperature and is saved as the ambientair temperature value once the initialising phase is completed. All of thedependent variables are calculated with this value.Note in the status line.This type of ambient air temperature measurement is sufficient forsystems which are independent of ambient air. During the initialising phase, ensure that the flue gas probe is held nearthe burner´s intake duct.

2. Measuring the ambient air temperature via a separate ambient airprobe

The probe is connected to the additional probe socket at the sideconnection panel of testo 300. As soon as a separate temperatureprobe is inserted, the temperature is automatically used as the ambientair temperature and is continuously measured.

In order to measure the exact flue gas temperature and therefore be ableto 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.

Example of measurement

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

Example:A separate ambient air probe is not used during the initialising phase oftesto 300. A separate probe is connected during the measurement. Thevalue measured by this probe is used immediately as the ambient airtemperature. The status display disappears.

A separate ambient air temperature probe must be used in systemswhich are independent of ambient air (ambient air is supplied, alreadypre-heated, to the burner).

Special probes are available for this purpose: a. Ambient air probe, 300 mm long ..................................0600.9791b. Ambient air probe, 100 mm long ..................................0600.9797

The c. Separate stub probe ....................................................0600.3692can also be used for continuous measurement of the ambient airtemperature.

3. You can call up the various measured values via the arrow buttons and .

4. If the measured values do not change, stop the pump. Place flue gas probe in fresh air. The measured values remain until you start the pump again by pressingSTART.

1. Start measurement by pressing START.

2. Place flue gas probe in the centre of flow:Search for the max. flue gas temperature FT and then fix the probe withthe cone in this position.

If the flue gas probe is in a vertical position or at an angle of 45° thecondensate drops which run down could result in a sudden drop in the

temperature.Remedy:Secure the flue gas probe as shown opposite.

After every measurement rinse the measuring cells with fresh air(Pump Start/Stop) until the O2 level is over 20.0 %

and CO and NO levels are below 50 ppm.

The flue gas probe is used to measure draught. The draught can bemeasured before or after a flue gas measurement.

Draught measurement/Pressure measurement

Example of 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 whenmeasuring the draught (fluctuations in the voltage influence the

measured result)!

If the draught is measured following flue gas measurementthere 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).

Zeroing the pressure sensor:Probe is generally outside the flue.Negative sign means underpressure, positive sign means overpressure inthe flue.

You can cancel the menu anytime by pressing the button. You thenreturn to the measurement menu without taking over the measured valueof the draught.

If started out ofinitialisation thenjump to theinitialising phase.

Do not measure for more than 5 minutes and start again at item 2 (setzero point) otherwise the measured values could lie outside tolerance

on account of drift in the sensor.

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 betweenthe sensor and the gas inlet. For this reason the measuring unit is not

explosion-proof.

Differential temperature measurement(testo 300 XL only)

Example of measurement

Only for measuring temperature e.g. flow/return temperature

For parallel measurement of the CO level in ambient air during a flue gasmeasurement.NoteParallel or subsequent measurement of AT is not possible.

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 theaccuracy of the measurement. Optimum measured results are attained bygently moving the probe back and forth. If the gases flow head-on onto thesensor the values measured will be too high.Measuring flue gas (START). The ambient CO value (in ppm only) ismeasured parallel to the flue gas values. The ambient CO value is alsosaved when the measured values are saved. Ambient CO can only bemeasured if the pump is operating.

Close protective cap.

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 ofsensor and adherence to accuracies).

Cigarette smoke influences the measurement (min. 50 ppm).A smoker´s breath influences the measurement by approx. 5 ppm.

Example of measurement

Leak detection probe(testo 300 XL only)

Do not use leak detection probe or testo 300 XL in closed rooms orfacilities 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.

Flue gas cannot be measured when operating the leak detection probe.You can measure max. 2 hours with the leak detection probe using a

fully recharged battery.Once the measurement is complete always remove the leak

detection probe immediately otherwise total discharge of the batterymay occur. Never leave the leak detection probe attached when

recharging the battery.

Service tipThe adjustable trigger limit in the factory is 200 ppm CH4 gas. The firstalarm limit can be finely adjusted within the range 0 to 1000 ppm (adjustonly in fresh air).

The memory in testo 300 is organised such that a so-called “designator”must be available to name a saved measurement. This designator can bemade up of maximum 20 alphanumerical characters.

A designator can be, for example:- the customer´s name- a customer number or- the name of a measuring location

Several measurements can be saved under one designator. If the function key is pressed repeatedly this enables themeasurements saved under the same designator to be numberedconsecutively. For example, “Testo 4” means that four completemeasurements are saved under the “Testo” designator.

Maximum 20 measurements can be saved in testo 300 M and maximum100 in testo 300 XL .

The maximum possible number of measurements depends on whethereach measurement is saved under its own designator or whether all themeasurements are saved under one designator.

There are 4 ways to select the designator in testo 300:

4. Reading in a designator with a barcode pen

The barcode pen automatically assigns the measured data to ameasuring location.

If a barcode label is available on location you can read it in with thebarcode pen.

The barcode pen is inserted in the RS-232 socket at the side of theanalyser and be plugged in and out if the analyser is on. Attaching thebarcode 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 whitesurface e.g. the barcode label.Then run the pen over the barcode strip. Correct transmission isconfirmed by a signal.

The designator is automatically added to the testo 300 XL designator listand is selected as the active designator. You, therefore, do not need toinput the customer´s number beforehand via PC or by hand into thetesto 300 XL. If you have a customer whose number is not yet saved inthe analyser, you can read in the number to testo 300 XL directly on location via the barcode. If a designator hasalready been read into testo 300 XL only this is activated.

Existing designators cannot be changed. Once an existing designator is edited with “Edit”it is then automatically seen as

new. The designator selected as the model remains unchanged.

Barcode pen only operates at a baud rateof 19200 (see ”baud rate” on page 24).

Data transmission

Data transmission to branch software

The measured values saved in testo 300 can be transmitted to your PC forfurther processing using branch software.

Connection from testo 300 - PC

The testo 300 and PC must be connected in order to be ableto send measured data from testo 300 to the branch software.

Setting up the connection

1. When switched off, testo 300 is connected via theanalyser - PC cable (0554.0154) to the serial interface in thePC (COM1 / COM2).

2. Switch on testo 300. It is not necessary to select a sub-menu to transmit the data. testo 300 is now ready to receiveand transmit data.

In order to enable transmission of data from testo 300 andthe software specific to that particular branch a partnership mustexist between the respective software house and Testo.

3. Start branch software.- Select serial interface (COM1 / COM2)- Transmit testo 300 to branch software

orread in designator (e.g. customer number) from the branch software to testo 300.

Adjusting the baud rate

The measured data is transmitted from testo 300 and the PC at a certainspeed 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 softwareInstruction 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 betweentesto 300 and PC.

Condensate trap

Maintenance

Flue gas probe

Cleaning the flue gas probe

If there is a large amount of dust in the flue gas the gas path sections infront of the pipe filter can become clogged or alloyed.

Cleaning the flue gas probeif the gas paths become clogged

Remove the probe pipe and place in hot water. Blow air through pipe orclean 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 outletwith a counterclockwise movement and pull out the tube to the left. Pullout the thermocouple on the tube.

Remove the bending protection spring and take the cable out of the slittube.

When inserting the new thermocouple do not press on the thermocouplelead. Press it into place with the help of a small screwdriver.

Only remove the thermocouple if it is defect. The thermocouple canbe damaged when pulled out of the connection tube.

Filtertube

An independent condensate trap with 2 particle filters is integrated inthe connection tube. Pull off one of the end pieces to let out thecondensate.

Note on changing filter1. If dirt can be seen on the output filter the inlet filter will have to bechanged.2. Filters must be changed if the pump power becomes (audibly) lower. Inmost cases it is sufficient to change the input filter.

Pull off the filter tube in order to change the filter material. Screw thedrawing key into the filter and remove it from the filter tube. Press thenew filter into the filter tube firmly. You can order spare material for the filterwith the Order no. 0554.3371. Please only use this filter.

The condensate trap can only be emptied if the pump is switched off.

The condensate trap is designed in such a way that there is a certainflow direction. This is marked with arrows on the housing section. If

gas flows in the opposite direction the condensate trap cannotfunction properly and this could lead to the instrument breaking

down.

When assembling the condensate trap, ensure that the sealrings are not damaged and that the filter tubules (A) do not get

mixed up.

German Calculation Information

The following equations are used to calculate the listed values:CO2max x (21% - O2%) CO2max : Fuel-specific maximum

CO2 value: CO2 = CO2 value21 % 21 % : Oxygen level of air in %

O2 % : Measured oxygen levelin %

A2 FT : Flue gas temperatureFlue gas loss: qA = (FT-AT) + B - KK AT : Ambient air temperature

(21 - O2) A2/B : Fuel-specific factors

21 : Oxygen level in airO2 : Measured oxygen levelKK : is a factor which can turn into a

negative value if qA falls below the temperature. Necessary for

measurements on burners.

If the fuel-specific factors A2 and B are zero, the Siegertsche Formula is applied using factor f:

(FT - AT) FT : Flue gas temperatureqA = f x AT : Ambient air temperature

CO2 CO2 : calculated CO2 valuef : fuel-specific factor

Burnerefficiency : Eta = 100 - qA If qA is negative, Eta will be greater than 100%.

Excess air CO2max CO2max : Fuel-specificvalue λ: λ = maximum CO2 value

CO2 CO2 : Calculated CO2 value

NOx: NOx = NO + NOadd x NO NOadd : NO2 addition factor

COundiluted : COundiluted = CO x λ CO: Measured CO valueλ: Excess air value

Cause / Remedy

1. Temperature probe not connected.2. Temperature probe is not connected correctly.Flue gas temperature and its calculated values are notmeasured, the remaining values are listed. Check thetemperature probe connection or insert new temperatureprobe.

The temperature probe for separate ambient airtemperature measurement is defective or not available.The last measured value is frozen. See page 12.

Admissible operating temperature is exceeded.The ambient air changes to non-permissible values.Adapt ambient air temperature.

Measurement of the zero point is not stable. Cause: O2 cell was changed but the specified time of 60min. for the cell to adapt was not adhered to. Switch off analyser and wait for adaptation.

O2 cell is worn-out. Change measuring cell.

Measurement of the zero point is not stable. Let theinitialising phase run several times.

There is still flue gas in the analyser or very highconcentrations were measured or the initialising phase istaking longer. Cause: Insufficient air was rinsed through following thelast measurement or the probe is in the flue gas.

Probe should be brought into contact with fresh air. Ifthere is still no change after several runs of the initialisingmode the cell must be defect or the cell is worn-out.

The analyser supply voltage is too low. If the batteryvoltage drops below 4.4 volt there is automatic switch-off. Recharge battery or connect to mains.

Measured value is greater than saved cutoff threshold.Remove the flue gas probe from the flue gas pipe andrinse the measuring cells with fresh air. Continue with themeasurement only if it is really necessary. Measuredcells may be damaged or destroyed! In the case of the gas path switch in testo 300 XLcan be set to O2/NO and the measurement can becontinued.

Measured values >500 ppm CO were measured whenthe ambient CO probe was used.Danger of poisoningMessage disappears once the values measured fallbelow <200 ppm CO.

(with testo 300 XXLL only)

testo 300 XL has an infrared interface for connection to the attachable printer.Press on the printer to release the lock.

The switch on the left side of the printer has the following 3 functions:left: OFF switch middle: ON switchright: Line-Feed (paper feed)

Self-test/Test printIn the OFF mode move the switch fully to the right (line feed) and if you keep thisposition for 3 seconds the character set saved in the printer will be printed as atest print.

Changing the batteryTo put in/change batteries or rechargeable batteries, open the batterycompartment (at bottom of instrument). Use 4 x 1.4 V alkaline or correspondingrechargeable 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 paperThe paper section is at the top of the printer. Open it and position the paper asshown in the diagram opposite.

Caution: The paper is thermal paper which means that only one side can beprinted. 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.

OFF ON Line-Feed

The printer is not powered via the hand-held instrument, therefore it mustalways be switched on and off separately.After approx. 8 min. the printer goes into a power save mode to save thebattery. Switch the printer off and then on again to reactivate it.

The attachable printer has a powerful bi-directional infrared interface with a databuffer in the printer. Once the button is pressed, the data is transferred inthe matter of seconds. The line of transmission should be kept free of obstaclesuntil the instrument has confirmed transmission.

The line of transmission should run in a straight line between the analyser andprinter and should not be blocked by obstacles.

The distance between analyser and printer should not be more than 1m.

If printing large amounts of text - more than 1 m text - we recommend you to attach the printer to the analyser.
