2.2 Special conditions for safe use

Safety | 2

2.2.1 Intrinsic Safety (Ex protection)

IRwin is certified intrinsically safe to prevent ignition of flammable atmospheres.

IRwin holds an ATEX certificate for EU and corresponding certificates for several other

regions as shown by the attached certificates, see Certificates [ } 98]).

For details of rating, see EX certification (intrinsic safety) [ } 24].

The "X" after the respective type certificate number relates to the following special conditions for safe use:

The only device allowed to be connected to the charging socket on any of the models

• IRwin SX

• IRwin SXT

• IRwin SXG

• IRwin SXGT is the Ex Certified IRwin Charging adapter (PN 580-604).

The charger or car adapter is subsequently connected to the inlet of the Ex Certified

IRwin Charging Adapter.

This means that the charger for IRwin S must, under no circumstances, be connected directly to the charging socket on any of IRwin models SX, SXT, SXG, and SXGT. See

also Charging the battery [ } 35].

IRwin SXnn is certified as intrinsically safe at an ambient temperature of -20 - +50°C.

Further temperature restrictions apply to oxygen and toxic gas measurment of IRwin

SXT and SXGT. See Certified Gas Measurement.

IRwin SXnn is certified for use in Gas groups IIA, IIB and IIC and in Zones 0, 1 and 2.

The external surface of the enclosure is therefore slightly conductive to prevent electrostatic charging and sparks. Labels added for marking purposes must not be larger than 400 mm

2

. If larger the instrument should not be used in gas group IIC,

Zone 0 applications. Natural gas applications are not affected by this regulation.

4 Description

4.1 Function

INFICON single-cell wide range technology

(patent pending)

The IRwin is a portable methane leak detector for gas pipeline survey. It measures following gases depending on the leak detector version:

• Methane

• Carbon dioxide

• Ethane

• Propane

• Butane

• Oxygen

• Hydrogen sulfide

• Carbon monoxide

There are several probes available for the leak detector:

• The carpet probe is used for surveying paved or smooth surfaces. Pull or push the carpet along the surface.

• Use the bell probe for measuring gas at specific points. Press the bell firmly down to pull gas through the surface.

• The hand probe is used for checking features on or in buildings. The hand probe also constitutes the handle for the carpet probe and bell probe.

• The Bar Hole probe is used to sample air from drilled holes. Push into hole and tighten screw to expand rubber before connecting sample line.

• The optional Hand Probe Flexible Extension can be connected to the hand probe or rod for easier access.

• The Swan Neck Probe is used on uneven surfaces and in bushes etc.

• The Flexi Bell is used for simple survey including meters and piping. The bell adapts to pipe geometry.

IRwin methane leak detector uses the unique INFICON single-cell wide range technology for detecting all concentrations from 1 ppm to 100 Vol% methane. This technology is very sensitive to the ethane content of natural gas. Therefore, large deviations can occur at higher methane concentrations if the ethane concentration is not compensated for. The instrument has built-in routines for ethane compensation.

The actual ethane concentration can be determined using the IR Ethane Analysis function. This can be used to automatically set the compensation concentration. If preferred you can instead set the ethane content manually. The safety certified modes

Ex and Ex Tox are not affected by this phenomenon. See "IR Ethane Analysis and compensation [ } 76]".


INFICON Description | 4

IRwin SXG and SXGT models also have GC Ethane Analysis capability for distinguishing between Natural gas (NG), liquid petroleum gas (LPG) and swamp gas by determining the presence of methane, ethane and propane in the sampled gas.

The GC Ethane Analysis function is not affecting the ethane compensation.

5.2 Assembling the probe system

WARNING

Risk of explosion due to not approved probe parts.

The original INFICON Hand probe is the only part of the probe system that is certified for use in potentially explosive areas. Other parts of the probe system, or third party accessories are not allowed in potentially explosive areas.

► Pay proper attention to safety when using other accessories for locating and pinpointing gas leaks in none classified areas.

NOTICE

The assembly of the probe system influences the response time stated in the technical data.

The probe system consists of the hand probe, the probe rod, the probe rod extension, the carpet probe and the bell probe. Each probe part is equipped with quick couplings and can be assembled according to the following graphics. The connection to the leak detector is made with the hand probe in all configurations.

The proper functioning of the system can only be assured with compatible probe systems of the manufacturer.

1 Attach the probe rod to the carpet or the bell probe.



2 Attach the hand probe to the probe rod.

3 Connect the probe tube of hand probe to the gas inlet of the leak detector, see

"Design of the leak detector [ } 15]".

Install the probe rod extension

To improve the ergonomics of the carpet probe, you can install the "probe rod extension".

1 Remove the male quick fitting (1) from the carpet using as 17 mm wrench.

2 Remove the tape covering the female thread of the extension rod (2).

3 Place the O-ring, found under the tape, flat on the bottom surface of the female threaded hole.

4 Screw the removed male quick fitting (1) in place in the extension rod (2). Make sure the O-ring stays in place by holding the extension rod (2)vertical. If desired you can use nut locking fluid to secure the fitting (1).



5 Remove the O-ring and clean the threaded hole on the black fork on the carpet

(where you removed the connector).

6 Place the O-ring flat on the bottom surface of the threaded hole.

7 Screw the extension rod in place in the carpet fork. Make sure the O-ring stays in place by holding the fork vertical.

IMPORTANT: Be careful when tightening. The fork is plastic and the threads are easily destroyed. If desired you can use nut locking fluid to secure the extension rod (2).

6.2.5 PPM Adjustment Factor

The PPM Adjustment Factor can be used to slightly overestimate low natural gas concentrations. This can be handy if bump test requirements require an indication of at least 10 ppm.

The selected value (1.0 to 2.0) will be multiplied with the calibrated reading.

Setting this factor to e.g., 1.4 will make IRwin display a 10 ppm reading as 1.4 x 10 =

14 ppm.

This adjustment affects values up to 10 ppm and turns into a minor offset above 10 ppm.

6.2.15 Calibration

The built-in calibration routines guide you through the adjustment of the leak detector sensitivity to the various test gases. You can set calibration intervals for the different adjustments and will then get a reminder when calibration is due ("Adjust calibration reminder").

Allow IRwin to warm up for 1 hour before calibrating for best accuracy.

Recommended calibration intervals

The calibration intervals for the operating modes Ex and Ex Tox are based on the TÜV certificates for these operating modes. For the other modes these time intervals are chosen to give you the best performance. Use the results of the various function tests to judge whether a calibration is needed. If you want to perform more than one calibration procedure at a given time you should run them in the following sequence for best performance.

1. Above Ground or Universal (low range) if Universal mode is enabled

2. Ex CH

4

(IRwin SX, SXT, SXG and SXGT only)

3. Tox (IRwin SXT and SXGT only)

Beside the calibrations of the application mode “Bar Hole” the application modes

“Gas Purity” and “Confined Space” will be calibrated in the higher measurement range (Vol%), too.

WARNING

Explosion, asphyxiation, toxic risk

Incorrect calibration leads to incorrect measurement results. Thus you are not properly warned against any possibly dangerous gas concentrations.

► Calibrate the leak detector only when you have been properly trained.

► Calibrate the detector in well ventilated rooms or outdoors.

The methane calibration is possible with gas mixtures in synthetic air only.

The natural background of CO

2

(typically 400 ppm) in ambient air will offset the calibration.

Fresh air exposure should, however, always be by ambient air.

After the leak detector has been calibrated with 100% methane it shows a few ppm increase in the measured value for a few minutes. This is a normal behavior of the leak detector and due to gas residues inside the leak detector.

Retrieving information about the calibration

The leak detector saves the date and the time of the last successful calibration.

Calibrate Above Ground / Universal (low range) first for best performance.

You don’t need to perform any of the calibration routines more than once for a complete instrument calibration.

We strongly recommend using so called ODFRs (On Demand Flow Regulators) to administrate calibration and test gases to the instrument. These regulators automatically supplies the exact gas flow aspired by the instrument and automatically shuts off when disconnected from the sample input.

It is also possible to use other calibration stations for the calibration. However, the following requirements have to be fulfilled.

• The gas flow delivered by the calibration station must be higher than the flow aspired by the leak detector. Set the gas flow to at least 80 l/h.

Calibration

INFICON

• The gas must be delivered at ambient pressure (i.e., do not push gas into the leak detector). The normal way to accomplish this is to create an open connection between gas container and detector inlet so that the excess calibration gas is vented to the ambient. This exhaust should be placed outside the test room, preferably outdoors.


► > > Calibration > Calibration (Tab)

ð Select the calibration to perform and click the check mark button.

ð The leak detector leads you through the process by indicating which gas to deliver to the detector in each step. Make sure that no residual gases are present in the ambient during Fresh Air step. Most common problems occur if you used 2.2 Vol% or 100 Vol% methane shortly before the trying to calibrate with 10 ppm or 100 ppm methane.

ð A successful calibration is confirmed by a green check mark.

ð A failed calibration is indicated by a red cross.

You can continue to use the leak detector even if calibration failed. The previous calibration parameters are restored.

6.2.15.2 Setting of calibration gas concentrations

Accuracy can be affected by calibration gas tolerance.

For optimum performance adjust the concentrations of the calibration gases set in the leak detector to the actual composition of your calibration gases.

For optimum performance of your leak detector you should use the proposed calibration gases. The exact concentrations of the gas delivered often deviates slightly from these values due to tolerance factors etc. The exact value is typically stated on the analysis certificate of the respective gas. You should therefore adjust the concentrations of the calibration gases set in the detector to match the actual

composition of your calibration gases, see "Concentration of calibration and test gases

[ } 34]".


1 > > Calibration > Settings (Tab)

2 Select calibration routine first and then select the gas to adjust (if several).

3 Confirm your selection with .

ð A window appears with controls for adjusting the gas selected.



4 Set the exact gas concentration value via drop-down menus. The leak detector shows the gas to adjust in the window and the currently stored concentration appears just below the setting line. You cannot set the concentration outside the range.

5 Select "Set" to confirm new value or "Reset" to restore the default value.

The "names" for the different calibration routines is not affected by the adjustment of calibration gas concentrations. The texts displayed during the calibration process will, however, show the adjusted values.

If using the same gas in several calibration routines, you must adjust the concentration of that gas in all relevant routines.

6.3.4.1 Automatic “Bar Hole” testing

The detector has an automated function for ventilating and testing the gas content in bar holes. This function will take three samples in the hole with a pre-determined evacuation time between the samples. Default setting is 10 s measurement and 3 minutes evacuation between samples. You can also set the detector to terminate the sequence when the CO

6.3.5 Operating mode "GC Ethane Analysis"

This mode is intended for determining if a gas sample is natural gas (NG) or liquefied petroleum gas (LPG), by identifying the methane, ethane and propane content.

Natural gas (NG) typically contain at least 0.5 vol% of ethane in addition to a high concentration of methane.

Liquefied petroleum gas (LPG) typically contain propane or butane or a mixture of the two.

These differences are the basis for identifying gas type from an hydrocarbon analysis.

While significant ethane content (>0.5 Vol%) in a methane rich mixture is a certain indication of natural gas, it is not entirely safe to say that no indication of ethane in a methane rich mixture is a certain indication of swamp gas.

Some natural gas contains no or only traces of ethane.

This can be due to several reasons, for example:

• The gas source is solely or partly liquefied natural gas (LNG) which sometime has very low ethane content.

• The gas source is solely or partly biogas.

• The natural gas source has very low ethane content.

Take sample for analysis.

Becomes active (blue) and cross disappears when natural gas concentration is high enough.

Detectable range ≥ 0.5 Vol% ethane in gas.

The following procedure is highly recommended on site to strengthen the evidence that a gas sample is indeed natural gas:

• Check that ambient temperature is within range for GC Ethane Analysis: 0 – 50°C

(32-122°F)

• Perform a GC Ethane Analysis Function test to check that the GC Ethane Analysis can detect ethane down to 0.5 Vol% in the gas sample. Gas used see

Concentration of calibration and test gases [ } 34]

• Make a GC Ethane Analysis on a sample of natural gas from the actual gas line at your site.

• Make a GC Ethane Analysis on the gas to be identified and compare the resulting curve to that obtained from the natural gas sample. Three consecutive tests with same result should serve as a clear result.

• If any doubt on this result remains perform a final function test to assure that the unit was working properly during testing.

If the ethane content in the natural gas is below 0.5 Vol% the GC Ethane Analysis cannot be used. The GC must also give a clear indication of ethane to serve as an indicator of natural gas. A clear indication is a ticked ethane box on the screen.

The IRwin GC is sensitive enough to detect 0.5 % ethane in methane.

The operator is fully responsible for evaluating the logic and likelihood of the correctness of the result being presented by IRwin, based on the ethane content in the tested gas, the maintenance and functionality of the IRwin Methane Leak Detector and other circumstances related to the issue.



NOTICE

Overloading the GC column with high gas concentrations will make analysis slow and possible non-functional

Move instrument away from leak area to fresh air directly after taking sample to avoid this. If you suspect overloading, you can make a prolonged column purge by pressing the sampling button (lower left) more than 3s.

Set Time Weighted

Average (TWA)

The leak detector has a TWA-Function (Time Weighted Average Function) with which alarms can be given according to LTEL (Long Term Exposure Limit) or STEL (Short

Term Exposure Limit). The LTEL value and the STEL value correspond to the maximum dose of a substance to which a person should be exposed over a defined period.

• STEL is the weighted average value over 15 minutes (for the respective toxic gas).

• LTEL is the weighted average value over 8 hours (for the respective toxic gas).

To set the Alarm Level for LTEL and STEL, see "Set limits and alarm levels [ } 79]".

NOTICE

The TWA calculations are reset when you switch from Ex Tox to another operating mode.

6.3.11 IR Ethane Analysis and compensation

Incorrect Ethane compensation value can result in significant deviation in the estimated methane concentration, in the operating modes "Above Ground", "Bar

Hole", "Confined Space" and "Gas Purity".

Why an IR Ethane

Analysis?

INFICON single-cell wide range technology

(patent-pending)

This function is mainly used to distinguish between natural gas and swamp gas from underground biological decay. Natural gas contains varying concentrations of ethane while swamp gas does not.

Such analysis is traditionally made with a gas chromatograph. With IRwin the same analysis with similar sensitivity is performed much faster. Instead of the typical 5 to 10 minutes a gas chromatograph requires for an analysis IRwin only needs a few seconds.

The second purpose of the IR-Ethananalyse is to establish the ethane concentration for compensation at high methane levels.

The IR-Ethananalyse can be made from below 1 to 8 Vol% ethane in the natural gas.

The resolution is 0.1% and the accuracy better than 1 Vol%.

IRwin methane leak detector employs the unique INFICON single-cell wide range technology to detect all concentrations from 1 ppm to 100 Vol% methane. This technology is very sensitive to the ethane content in the natural gas. Therefore, large deviations can occur at higher gas concentrations if the ethane concentration is not compensated for.

The leak detector has a built-in routine for ethane compensation. The ethane content can be entered manually, if known. A more practical way is to use the IR-

Ethananalyse function to measure the ethane content and automatically set the compensation concentration. The safety certified modes Ex and Ex Tox are not affected by this phenomenon.

IRwin SXG and SXGT models also have GC Ethane Analysis capability for distinguishing between Natural gas (NG), liquid petroleum gas (LPG) and swamp gas by determining the presence of methane, ethane and propane in the sampled gas.

The GC Ethane Analysis function is not affecting the ethane compensation.

76 / 128

6.3.11.1 Entering ethane concentration manually

If you know the current ethane concentration in your natural gas you can enter this value manually. We recommend, however, that you use the built-in IR-Ethananalyse to determine the ethane concentration as this typically varies from day to day and from location to location.




1 > > IR Ethane Analysis > Settings (Tab)

2 Select "Ethane (%) for Compensation".

3 Set the desired ethane concentration.

ð The value shown is the current setting. The last value (indicated by an “A”) is the result of the last IR Ethane Analysis.


6.3.11.2 Setting reminder for IR Ethane Analysis

You can set the detector to remind you to make an IR-Ethananalyse. If set, the detector will ask if you want to perform a new IR-Ethananalyse or keep the current value.

1 > > IR Ethane Analysis > Settings (Tab)

2 Select ”Reminder for Ethane Compensation Analysis”.

3 Select between the following settings:

Off

Start-up

Always

No reminder

Reminder first time you enter "Bar Hole" mode after start-up of detector (10 s delay)

Reminder every time you enter "Bar

Hole" mode (10 s delay).

6.3.11.3 Performing IR Ethane Analysis after automatic reminder

You need a methane concentration in the range of 5 to 15 Vol% to perform the IR-

Ethananalyse. The compensation is only needed for high gas concentrations and is therefore only needed when you have found a significant leak.

You should connect the Bell probe before performing the IR-Ethananalyse.

1 Change to operating mode "Bar hole".

ð If reminder is activated a window will appear showing the current ethane concentration setting. The leak detector asks if you want to keep the current value or a make a new analysis.

2 Select "New” and press the bell firmly down onto the place where you found the gas.

ð A number between 0 and 100 appears on the display.

3 If the value is smaller than 20, push the probe harder onto the surface or look for a place with higher methane concentration. If the value is higher that 80 you should move the bell away from the leak to find a spot with lower concentration.



ð Try to make the signal stabilize at a value between 20 and 80. When succeeding, the detector will need another 2-3 seconds to calculate the ethane concentration. The result is displayed as % C

2

H

6

.

ð Press check mark to continue. IRwin will ask if you want to "Save Ethane

Concentration for Compensation".

ð Select "No" if analysis was made for confirming natural gas or "Yes" to use for compensation. If selecting "Yes" the value is saved as ethane concentration and shown in the C

H

6

field.

See Operating mode “Bar Hole” [ } 58].

ð An ethane concentration value of 1 % or higher is a safe indication of natural gas. A value between 0.4 and 1 % is a probable indication of natural gas.

If the measured ethane values are between 0 and 2% it is recommended that you repeat the measurement at least 3 times on the same position to check the result is consistent.

6.3.12 Set limits and alarm levels

WARNING

Explosion hazard

Irwin S is not certified for use in explosive atmospheres and is also not suitable for estimating fire potential (LEL level).

Alarm indications:

Gas alarms are usually separated into three levels of severity:

Priority Alarm

Low AL1

Medium AL2

High AL3

Display and status LED

Red, flashing (1 Hz)

Red, flashing (1.5 Hz)

Red, steady on

Acoustic signal

1 Hz

1.5 Hz

Steady on

The detector will beep and the status LED and the display will be red if the measured gas concentration exceeds a set alarm level (below threshold for O

2

alarms AL1 and

AL2).

Faster flashing or beeping will indicate more severe conditions. See table above.

The oxygen alarm differs from the other in that the main risk (asphyxiation) is associated with low oxygen. The alarms AL1 and AL2 for oxygen warns when the oxygen concentration goes below the respective alarm level. AL3 for oxygen is activated when oxygen concentration exceeds AL3.

The % unit in the settings menu means % of LEL for Ex and Ex Tox operation modes and volume % for all other modes. In the operating modes "Above Ground", "Confined

Space" and "House" you can also set a PPM level alarm to help when surveying for leaks.

The acoustic signal and the status LED are the primary alarm signals of the operating modes "Ex" and "Ex Tox".

6.3.14 Performing function tests

Correct readings only if settings are correct.

If the leak detector does not work correctly, it may not show every leak.

► Test the leak detector regularly as recommended.

Use the Function tests to test the status and accuracy of the leak detector. The leak detector will guide you through the test procedures and tell you when operator actions are needed.



Recommended

Function test intervals

(based on IRwin model)

Once you have set the function test intervals, the leak detector will remind you to

perform the respective Function test, see "Setting the Function Test Interval [ } 48]".

You can use different calibration stations for the Function tests. However, the following requirements have to be fulfilled.

• Best choice is to use On Demand Flow Regulators (ODFR) that opens automatically when IRwin pulls gas delivers the exact amount required. If using a conventional pressure regulator type, make sure gas flow through the calibration station is higher than the gas flow of the leak detector.

• The gas must not be fed with over pressure into the leak detector. This is best taken care of by using "ODFR" regulators.

ü To perform the Function test, you need fresh air and either 10 ppm CH

3 Select the desired function test from the list.

4 Start the selected Function test by pressing .

ð The leak detector guides you through the process.

You can display the date of the last function test.

► > > Function Test > Info (Tab)

This time is the basis for the next function test reminder. Refer to "Setting the Function

Test Interval [ } 48]".

Function tests expects factory default concentrations. Using other concentrations, even if within the adjustable calibration concentration range, can make the automatic function test interpretation invalid.

If you fail function test and you are using non-standard gases we recommend that you test the instrument by simply exposing the respective mode for the test gas and observe the reading. This way you can still verify the function but the last passed function test will not be logged if automatic interpretation failed.

6.4 Measuring

ü

Connect the leak detector to the desired probe. See "Function [ } 14]".

1 Switch on the leak detector by pressing the I/O key.



2 Complete the self test.

3

Make sure that the desired basic settings are correct. See "Initial setup [ } 44]".

4 Make sure that the settings for the desired operating mode are correct. See

"Operating modes [ } 54]".

5 Switch to the desired operating mode.

6 Consider all relevant regulations for the operation in question.

7

Record the measured values if desired. See "Logging data to file [ } 82]".

8 Start measuring.

6.5 Perform self test

When you turn on the leak detector it will automatically perform a self test for the main components such as software and parameter memories, battery, gas sensors, valve(s), pumps, buzzer and status LED.

If not all test are passed successfully it may be that some operating modes cannot work properly. That is indicated by the status LED being yellow. The test can, for example, fail because you accidentally blocked an inlet during the test.

If the problem has been solved it is possible to re-start the self test sequence and get the detector into normal operation mode without having to re-start the complete system.

6.11 Switching OFF

1 Press the "On / Off” key for 3 seconds.

ð The leak detector asks whether you want to switch off the instrument.

2 Select “Yes” and press the check mark key.

Some errors can make the leak detector go into watchdog state. The acoustic alarm beeps continuously and the status LED is red. The leak detector may not even be reacting to the menu buttons. If this happens you must turn the leak detector off. Press and hold the "On / Off” key until the detector shuts down (roughly 9 s).

Do not use this option without cause. You risk losing settings and the bias of the oxygen sensor on SXT and SXGT models. This leads to a prolonged warm up at next power on. It can take up to 12 hours to stabilize the oxygen sensor if sensor bias is lost form more than a few minutes. If you need to do a hardware switch off you should restart the leak detector immediately, If the leak detector malfunctions again you will need to contact INFICON service.

1 Press the "On / Off” key for 9 seconds.

2 Restart the leak detector as soon as possible to restore O

2 sensor bias (IRwin

SXT and SXGT).

Warnings

6.12 Warnings and error messages

Warnings are given for conditions that can impair the accuracy of measurements. The operation of the leak detector is normally not interrupted but some functions may be barred or indicated as non-compliant by status LED being yellow and values being red instead of black.

If the navigation button “Menu“ is colored red this means that there has been an error that you have not yet checked. If the cause of the error remains there will be a new warning/error alarm and a new entry in the error log. The navigation button turns blue again when you have read the warnings list.

Open the warnings log list:

► > > Warnings

Error messages Errors are events that force the interruption of the operation. Errors are also logged in the warnings log list.



The division between errors and warnings is sometimes not very clear. In both cases it is worth restarting the detector to try to pass the self -test again. Charging the battery also reduces the risk for some errors and warnings.

INFICON Maintenance | 7

7 Maintenance

The gas inlet of the instrument, as well as the probe system include various filters.

These must be replaced at intervals specified in the maintenance plan. If the leak detector is used in dirty environments, more frequent replacements may be necessary.

NOTICE

The internal sample inlet filter can become clogged.

Running the leak detector with no probe connected can make the internal filters clogged. This can cause need for service.

7.3 General check of the probe system

The probe system used must be checked regularly for external damage and leaks.

1 Examine all parts of the probe system for external damages.

2 Check that the rubber grip of the Hand Probe is not broken or missing.

The rubber is certified anti-static and must be replaced by original INFICON spare if damaged or missing.

3 Connect the probe system to the instrument.

4 Block the inlet of the probe system.

ð If the error message "Blocked flow alarm" appears, the probe system is sufficiently leak-proof. When the leak detector does not show an error there is a leak in the system.


INFICON Maintenance | 7

7.4 Maintenance of the Leak Detector

7.4.1 Seasonal shut-down

IRwin SXT is using a small amount of power when shut off. This allows the clock to continue running and the function of oxygen sensor to be maintained for faster warmup.

When you want to store the leak detector up to 3 months charge it fully.

When you want to store the leak detector more than 3 months select one of the following possibilities.

Connect the charging equipment and leave the charger on.

OR:

Charge the battery every 3 months as long as you store the leak detector.

7.4.2 Change the cigarette filter in the sample inlet

► Change the filter according to the maintenance plan, see Maintenance plan [ } 89].

Be careful when checking the cigarette filter in the inlet, make sure that it is not deformed, otherwise it will loose part of its function. Replace the filter if in doubt.

7.5 Maintenance of the Hand Probe

Replace the filter in the tip of the probe according to the maintenance plan, see

Maintenance plan.
