Preface

Dear Testo customer,

Your decision to buy the testo 300 XXL was an excellent choice.

The testo 300 XXL is designed for flue gas analysis and all measurements inheating systems.

Thousands of customers buy our high-quality products every year. There are atleast 7 good reasons for this:

1) Our price/performance ratio is good. Reliable quality at a fair price.

2) Substantially extended warranty periods up to 2 years – depending on the model.

3) We provide an optimum solution to your measuring tasks with over 40 years ofprofessional experience.

4) Our high quality standards are confirmed by the ISO 9001 certificate.

5) Of course, our devices also bear the CE label required by the EU.

6) Calibration certificates for all relevant measurements. Seminars, consulting andcalibration on site.

7) We don’t leave you on your own after your purchase.

Use the device only in the operating andmeasuring ranges specified in “Technical data”.

Use the device only under the conditions and forthe purpose for which it was designed. For this,particularly observe the safety information and thetechnical data.

To prevent damage to the instrumentation anditems under test, suitably trained persons shouldonly use the equipment.

Observe all local Health and Safety regulationsbefore operating the test equipment.

Do not make measurements on live components.

Observe the warnings on the control unit andanalyser box!

Magnets of the control unitThe magnets of the control unit can damage ECcards, telephone cards etc.

Operation with mains adapter Use only the original mains adapter to operate thedevice. Replace damaged mains cable only withan original mains cable of the manufacturer oragent (i.e. by authorised service).

Check for leaksThe entire measuring system (probe, condensationtrap, filter, hoses and connections) must bechecked for leaks before each measurement, e.g.by pushing on a collapsed rubber bladder.Measuring errors can be caused if external airinfiltrates.

Expose the gas outletWhen measuring, ensure that the gas outlets areexposed to allow the gas to escape unobstructed.If this is not the case, the measurement resultscan be falsified.

Empty the condensation trapThe condensation trap must only be emptied whenthe pump is switched off (the measuring cells areotherwise in danger of damage)!

Disposing of batteriesThe end user is legally required to dispose of allused batteries in accordance with their country’sregulations.

Disposing of measuring cellsStoring the analyser in rooms containing solvents,vapours or gases will damage the measurementcells e.g. cleaning fluids, polishes, paints, cookingoperations. Protect the device from direct sunlightand store at temperatures <45°C.

Storing the deviceStoring the analyser in rooms containing solvents,vapours or gases will damage the measurementcells e.g. cleaning fluids, polishes, paints, cookingoperations. Protect the device from direct sunlightand store at temperatures <45°C.

Charge the battery before useBefore making the first measurement or afterseveral days of disuse, fully charge the internalbattery (see menu Service Operating values). Charge the battery at leastevery 4 weeks during longer periods of disuse toprevent damagingly low discharging.

Changing the configurationSwitch off the device to change the configuration(e.g. probe change), as the device reads theprobe-specific values when it is switched on.

PC cable connectedWhen the PC cable is connected, it is impossibleto issue a print command.

Using probes with plug headEnsure the good contact of probes with plugheads. Fully tighten the union nut on the probehandle.

Opening the deviceIf the device is opened, misused or subjected toforce, the warranty will be voided.

Because the pressure sensor heats up, it isrecommended to wait on the “Warm up” for 15minutes to achieve the best possible accuracy.

Example measurementCorrect use of the flue gas probe

The measurement of the flue gas temperature is made bythe thermocouple at the tip of the flue gas probe. The probetube protects the thermocouple, but has openings in toallow the stream of flue gas to envelop the thermocouple.

Thetemperature

measurement is made during the zeroing phase. The fluegas probe can be adjusted in the flue at this time (Note: theAT probe must be connected). This makes it possible toconduct a core current search during the zeroing phase. Thetemperature measured by the flue gas probe is interpretedby the testo 300 XXL as the combustion air temperatureunless a AT probe is connected (Note: the probe must beremoved from the flue). When the zeroing phase has beencompleted, this value is saved as the combustion airtemperature value.

All dependent parameters are calculated by this value.

incorrect

Flue gasstream

Thermocoupleincorrect

correct

correct

The thermocouple must always be exposed to the streamof flue gas to allow an exact measurement of the fluegas temperature and thereby a precise determination of

the flue gas losses. It must not be screened by a web ofthe probe pipe.

The tip of the thermocouple must not touch the guard. Ifnecessary, bend the tip of the thermocouple accordingly.

Example measurement

A draught measurement is only possible with the pumpswitched off. The + pressure inlet of the device must beopen!

Do not change between battery and mains operationduring the draught measurement (voltage fluctuationsinfluence the result of the measurement)!

If you conduct the draught measurement after a flue gasmeasurement, a head of pressure exists in the hose afterthe pump has stopped, which must be dispelled. Thisoccurs within approx. 30 seconds.

Remove any traces of condensation in the flue gas probe(shake out the probe with the tip towards the floor).

Differential pressure measurement with the control unit

Example measurement

Do not use in the main duct!

Ensure that there are no leaks between the samplingpoint and the device (escaping gas and atmosphericoxygen can create an explosive mixture)!

Do not smoke or use naked flames during themeasurement!

Observe the rated pressure of the connections!

Do not exceed the measuring range!

No gas enters the device because an air cushion formsbetween the sensor and the gas inlet. The measuring unitis therefore not protected against explosions.

Explosive and flammable gases, particularly natural gas andpropane, are detected by the gas leak probe even in lowconcentrations in the air. For example, suitable for findingleaks in gas pipes, vessels and equipment.1 Connect the probe before switching on the

testo 300 XXL.

2 After the device has been switched on, the warming upphase of the leak detection probe is automatically started(approx. 30 sec). Green, yellow and red LED, steadytone.

3 Ready for use Green LED flashes steadily, steady tone stops.

4 Conduct leak detection:• When gas escapes, acoustic signal

(ticking) is audible, becoming faster with increasingconcentration.

• When the 1st switching limit (> 200 ppm) is exceeded,yellow LED flashes.

• When the 2nd switching limit (> 1%) is exceeded, redLED flashes, steady tone. No readings of the gas leakprobe are indicated in the display.

The power supply of the gas leak probe is provided by thecontrol unit.

29

Service tip:The trigger limit is factoryadjusted to 200 ppmCH4 gas.

The 1st alarm limit canbe finely adjusted in arange from 0...1000 ppm(perform in fresh air only).

Example measurementGas leak probe

with control unit

Do not use the gas leak probe and testo 300 XXL inenclosed rooms or facilities in which gases have

accumulated into an explosive mixture.

The use of other electrical equipment is also prohibited.

It must be ensured that the gas concentration does notexceed 20% LEL.

Duration of measurement with the gas leak probe with fullycharged battery, maximum 2 hours.

Remove the gas leak probe from the deviceimmediately after the measurement to prevent heavybattery discharge.

Never leave the gas leak probe connected when chargingthe batteries.

The measured CO2 value depends on the absoluteatmospheric pressure. This effect is compensated by thedevice internally. For this, enter the absolute pressure of

the location in the main menu. The displayed CO2 valueis automatically compensated to the entered absolutepressure.

To avoid the effects of the CO2 content of respired air, holdthe probe as far away from your body as possible.

The measuring principle is based on infrared absorption.This type of probe has a relatively high powerconsumption. For long-term measurements, use themains adapter and rechargeable batteries.

If sudden changes occur in the concentration, the probewill require 30 – 60 sec. to adapt to the environment.Gently waving the probe reduces the adaptation time.

The memory organisation of the testo 300 XXL is designedsuch that a so-called “Location” must exist to identify asaved reading. This location can consist of up to 20alphanumeric characters.

For example, a location may be:- the name of the customer- a customer number or- the designation of a location.

Several measurements can be saved for each location. Thisis possible by pressing the function key “Mem.” severaltimes.

It is also possible to place locations in directories(see Measurement data processing).

The maximum possible number of measurements dependson whether each individual measurement is saved with itsown location or all measurements are saved exclusively withone location.

The barcode pen is connected to the RS-232 socket on thebottom of the device and can be connected anddisconnected whilst the device is switched on.

Activate the barcode pen by holding the tip of the pen brieflyagainst a white surface, e.g. the barcode label. Then movethe pen evenly and quickly in direct contact across thebarcode pattern. A correct reading is indicated by a signaltone.

The location is automatically accepted in the location list ofthe testo 300 XXL and is selectzed as the active location. Itis unnecessary to read or manually enter the customernumber of the customer where you are measuringbeforehand with a PC or by hand into the testo 300 XXL.When you visit a customer whose customer number is notsaved in the device, you can read the number directly onsite by the barcode into the testo 300 XXL. If the locationread by the barcode pen already exists in the testo 300XXL, this is activated.

Notes:

The given measuring ranges are recommendations toachieve the highest possible accuracy. Higher deviation is tobe expected outside these measuring ranges.

Note: The toxic sensors may be damaged if COconcentrations are greater than 40 000 ppm. Remove thetoxic sensors during applications of this kind in order toprevent the sensors from being damaged. Measurementscan be carried out in this range using the O2 sensor.

CO`s lower explosion limit is reached if CO concentrations ofmore than 10.8 % (108 000 ppm) come into contact with air.

The lower explosion limit is significantly lower in combusionprocesses such as wood combustion due to the nonburnedhydrocarbons and hydrogen.

PRESSURE

NoteThe absolute pressure is determined in the measuringprocedure depicted to the side. The absolute pressureresults from• Altitude pressure (metres above sea level)

This has an annual average at sea level of 1013 mbar. Thehigher the location is above sea level, the lower thepressure.

• Barometric pressure This has an annual average independent of the altitude1013 mbar. This pressure can fluctuate from the annualaverage by approx. ±20 mbar depending on the weather(see local barometer display).

• Differential pressure This is the higher or lower pressure in the duct.

The entry of the absolute pressure (in hPa only; it isimpossible to switch to other units) has an effect on thepressure-dependent measurement values. These areautomatically compensated by the pressure: for humidity(g/kg, J/g), CO2 and in all thermal probes!
