2.0 Introduction
This manual explains how to use the GEM5000 landfill gas analyser. The GEM5000 has
additional functionality to the GA5000 gas analyser. The GA5000 measures gas
concentrations only, whereas the GEM5000 measures flow and gas concentrations. The
GEM5000 measures flow and calculates the calorific values of the gas as well as being a
useful tool for balancing the gas field. The GEM5000 gas analyser may be used to monitor,
calculate, adjust and record the flow at each monitoring point.
This instrument may also be used in GA5000 mode of operation if required. The operator
may change the analyser between a gas extraction monitor (a GEM5000 gas analyser) or a
landfill gas analyser (a GA5000 gas analyser). The mode of operation can be changed from
the ‘Special Action’ menu. Please refer to section ‘8.0 – Taking Readings’ for further
instruction.
The 5000 series of gas analysers complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including interference that may cause
undesired operation.
2.1 Safety instructions
Warning
The 5000 series of gas analysers can be used for measuring gases
from landfill sites and other sources as described in this manual.
The operator may be exposed to harmful gases during the use of the
instrument. Inhaling these gases may be harmful to health and in
some cases may be fatal.
It is the responsibility of the user to ensure that he/she is adequately
trained in the safety aspects of the gases being used and appropriate
procedures are followed. In particular, where hazardous gases are
being used the gas exhausted from the analyser must be piped to an
area where it is safe to discharge the gas.
Hazardous gas can also be expelled from the instrument when
purging with clean air.
The instrument has been designed to be used in explosive
atmospheres as defined by the classification. The instrument can be
configured to measure low levels of several gases, but may not be
certified for use in potentially explosive atmospheres of these gases.
It is the responsibility of the operator to determine the protection
concept and classification of equipment required for a particular
application and whether these gases create a potentially explosive
atmosphere.
Note: Gas analysers are a sensitive piece of scientific equipment, and should be
treated as such. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the instrument may be impaired.

acidic liquids or gases that may attack metals, or solvents that may affect
polymeric materials, then it is the responsibility of the user to take suitable
precautions, e.g. regular checks as part of routine inspections or establishing from
the material’s data sheet that it is resistant to specific chemicals that prevent it
from being adversely affected, thus ensuring that the type of protection is not
compromised.
The relative pressure range is +/-500 mbar. Note, however, that the input pressure
should not exceed +/- 500 mbar relative to atmospheric pressure and the output
pressure should not exceed +/- 100 mbar relative to atmospheric pressure.

2.3 MCERTS (applied for)
MCERTS is the UK Environment Agency's Monitoring Certification Scheme. The scheme
provides a framework within which environmental measurements can be made in
accordance with the Agency's quality requirements. The scheme covers a range of
monitoring, sampling and inspection activities.
The GEM5000 instrument is MCERTS certified only if:
The MCERTS logo appears on the screen after initial power on.
Note: MCERTS - Cross sensitivity tests using hydrogen sulphide were not carried
out on this instrument. Therefore, users should be aware if H2S is present
on sites, as there may be an interferential effect.
MCERTS promotes public confidence in monitoring data and provides industry with a
proven framework for choosing monitoring systems and services that meet the
Environment Agency's performance requirements.
The Environment Agency has established its Monitoring Certification Scheme (MCERTS) to
deliver quality environmental measurements. The MCERTS product certification scheme
provides for the certification of products according to Environment Agency performance
standards, based on relevant CEN, ISO and national standards.
MCERTS certified instruments have been tested by an independent body to ensure that
they meet certain performance requirements. In addition the manufacturer of an MCERTS
product is regularly audited to ensure that the performance requirements of the
certification are being continually met.
The 5000 series of gas analysers have been certified to Version 3.1 of the ‘Performance
Standards for Portable Emission Monitoring Systems’.
2.4 CIRIA
The CIRIA guideline ‘Assessing the risks posed by hazardous ground gases to buildings’
proposes that gas concentrations and flow rates should be monitored.
As an example methodology, they suggest using a gas analyser to first measure flow and
pressure and then afterwards to measure gas concentration.
The logging profile option offers frequency of data to be collected within a timed period
which, in return, identifies a gas profile of the sample point being monitored, information
about whether the sample point is performing correctly, when the peaks occur and
whether air is drawn in after a certain period. This logging option is available on firmware

software version 1.6.5
Versions of the GA5000 analyser range with internal flow on firmware version 1.6.5 and
above have the ability to take measurements according to the CIRIA guidelines, while still
allowing other users to take the measurements as before.

4.0 GEM5000 optional products and accessories
4.1 Optional products
The GEM5000 gas analyser has a number of optional products for purchase which enhance
the usability and enable further analysis of data and reading information.
Note: For more information on the features listed in this section please contact Sales at
Geotech on +44(0)1926 338111 or email [email protected].
4.1.1 Pitot tube (optional)
The GEM5000 gas analyser enables the use of a pitot tube to aid accurate flow
measurement. The pitot tube is used for gas extraction systems and the pressure
readings are taken in mbar. High gas flow is calculated in the analyser in m3/hr (metres
cubed per hour).
4.1.2 Orifice plate (optional)
Geotech recommends the use of orifice plates as good practice when using the GEM5000
gas analyser, enabling repeatability in flow measurement via a fixed method. Orifice
plates are a specialised product and configuration and Geotech does not currently
manufacture or sell spare parts for this product. Please refer to a specialist supplier if
the use of Orifice plates is required.
4.1.3 Temperature probe (optional)
The GEM5000 gas analyser has the facility to automatically display and record the
borehole temperature via an optional temperature probe.
When a temperature probe is fitted the temperature reading will be displayed on the
‘Main Gas Read Screen’ and recorded with all other data.
Note: Temperature probes with an Ex label are part of the GEM5000 Ex certification
SIRA 11ATEX2197X and IECEx SIR11.0089X, and therefore certified for use
under the same conditions as the analyser.
4.1.4 Anemometer (optional)
The GEM5000 gas analyser has the facility to automatically display and record high flow
via an optional anemometer probe. It is designed to plug into the instrument and
instantly provide a flow indication. An anemometer probe adds flow measurements to
the professional reporting ability of the GEM5000 range along with gas concentrations,
pressure and temperature.
The anemometer has a simple connection, a narrow diameter measurement head
(11mm), a wide temperature operating range (up to 80oC) and indicates flows up to 40
m/sec.
When an anemometer probe is fitted to the analyser the flow will be displayed in the
‘Main Gas Read Screen’ and recorded with all other data.
Flow can be measured in either m/s (gas velocity) or m3/hr (volume flow rate). In order
to calculate the volume flow rate the pipe diameter will need to be entered into the
instrument, either manually or via the Gas Analyser Manager software.
Note: The anemometer probe is part of the analyser Ex certification BVS 04ATEXE194
for use with ATEX only and is therefore certified for use in a potentially
Page 18

explosive atmosphere. To use the m3/hr option the firmware software within
the analyser must be set at the time of manufacture.
4.1.5 H2S filter (optional)
The GEM5000 gas analyser has the capability to use an H2S filter and is required as
standard if the compensated CO cell is fitted and configured at the time the instrument is
manufactured. H2S gas can have a cross-gas effect on the CO reading. By using a filter,
the H2S is removed from the gas sample, therefore providing a more accurate CO
reading.
The filter only needs to be used when you are trying to get rid of any possible cross gas
effects H2S might have on other gases. Do not use the filter on all boreholes.
4.1.6 Gas analyser manager – GAM (optional)
Gas Analyser Manager (GAM) enables the operator to maximise the operation of the gas
analyser. It enables direct communication with the unit, features a simple upload and
download facility and is fully compatible with the latest Microsoft™ operating systems.
Features:
Organisation and transfer of borehole IDs and readings to and from the gas
analyser.
Configuration of the gas analyser.
Flexible grouping of the IDs.
Structured organisation of transferred data.
Automatic detection of instrument type and available options.
Secure data mode to prevent tampering.
First time set-up wizard.
Enable flow measurements for GEM5000 gas analysers.
4.1.7 GPS (optional)
An optional GPS feature is available for the GEM5000 gas analyser. It enables the site
engineer to automatically locate borehole IDs using GPS satellite signal from predefined
borehole IDs uploaded from Gas Analyser Manager or set on the analyser when out in the
field prior to taking a reading. The GPS reading data is stored for each measurement
reading providing an audit trail confirming that a reading was taken.
4.1.8 Bluetooth dongle (optional)
An optional Bluetooth feature enables the operator to set and utilise Bluetooth
technology. This may be useful when downloading gas readings from the analyser to the
PC instead of connecting the analyser to a PC via a USB lead. Bluetooth may also be
used to transfer Site IDs to other 5000 series gas analysers if required. Bluetooth is
activated by plugging the dongle into a pc USB port and switching on the Bluetooth
option feature in the settings on the analyser.

The instrument should be discharged and fully charged at least once every four weeks,
regardless of indicated charge state.
6.9 Battery/charging
The battery used in the 5000 series of gas analysers is nickel metal hydride and
manufactured as a pack from six individual cells. This type of battery is not so susceptible
to the top-up charging ‘memory effects’ as nickel cadmium batteries, although it is not
recommended that the unit is given small top-up charges.
Note: To reach optimum charge, it is recommended that the instrument is
switched off when being charged and remains switched off during the
charging process.
A full charge will take approximately 4 hours from a fully discharged battery.
Warning
The battery charger is NOT covered by the Ex certification.
The battery must be charged only in a safe area.

analyser. Change using ‘Special
Actions’.
Step 3 The instrument has the correct
time and date set.
Step 4 The water trap filter is fitted and
is clean and dry.
Step 5 The battery has a good charge
(minimum 25% charge, even if
only a few readings are required).
Step 6 The channels CH4, H2S and CO
have been zeroed, without gas
concentration present.
Step 7 If necessary check the span
calibration with a known

Warning
Inhaling hydrogen sulphide gas (H2S) or other harmful gases can cause
death. It is the responsibility of the user to ensure that he/she is
adequately trained in the safety aspects of using H2S and other harmful
gases. In particular, where hazardous gases are being used the gas
exhausted from the analyser must be piped to an area where it is safe
to discharge the gas. Hazardous gas can also be expelled from the
instrument when purging with clean air.
Good practice
Travel to site with the gas analyser in the vehicle's interior - not in the boot, where it
may be subjected to extremes of temperature and possible shock damage. Do not
place the gas analyser against anything hot (e.g. gas extraction pipe, car body or in
an unattended car during the summer) as this will cause a temperature increase in
the gas analyser and may cause erroneous readings.
When moving around a site, protect the gas analyser from strong direct sunlight and
heavy rain.
Always use the water trap! If the water trap becomes flooded, change the filter and
ensure all tubes are clear of moisture before re-use.
Note: If the exhaust of a 5000 series gas analyser is connected to a
pressurised system then this results in a flow of gas out of the inlet flow
port.
8.2 Update site data
Prior to taking the readings at a particular site, the site data should be updated. This is
accessed via the ‘Special Action’ menu. The answers to these questions are then stored
and appended to each reading stored thereafter, until the site data is updated for another
site. If using Gas Analyser Manager (GAM) software this data will be uploaded to GAM
along with the reading data.
8.3 Special action

analyser) mode of operation if required. From the ‘Special Action’ menu, select the middle
soft-key to toggle between GEM and GA Mode.
GEM analyser in GA mode - main gas read screen
Note: For operating instructions on how to use the GA5000 mode of operation,
please refer to the GA5000 gas analyser operating manual.
8.5 The gas flow measurement screen
The GEM5000 gas analyser enables gas and flow measurements to be recorded by using:
A flow device i.e. a PITOT tube, Orifice plate, Accu-Flo or anemometer.
A temperature probe.
The GEM5000 instrument has the extra functionality to measure the calculated calorific
value of the gas. The site engineer uses the information recorded by the analyser to make
adjustments to the gas flow for specific boreholes. The initial and adjusted flow rates are
recorded.
Page 49

Copyright Geotech Page 49
8.6 How to use an anemometer (optional)
The GEM5000 gas analyser has the facility to attach an anemometer device enabling the
site engineer to measure the flow of gas within an extraction system. The anemometer
can be set to display two values; m/s (meters per second) and m3/hr (metres cubed per
hour).
It is best practice to take the gas reading first before taking the flow reading with the
anemometer attached.
If using a ‘borehole ID’ the internal pipe diameter can be predetermined in the optional
Gas Analyser Manager (GAM) software. Once set, the site engineer cannot edit the pipe
diameter setting.
If the site engineer is not using a borehole ID or the pipe diameter is not set in GAM the
operator will be prompted to enter a pipe diameter with a new ID on the analyser. Select
soft-key ‘Next ID’ from the Main Gas Read screen, followed by soft-key ‘Add’ and add a
new borehole location.
In order to use the anemometer it is important to know the internal diameter (ID) of the
pipe if you want to calculate the flow in m3/hr (metres cubed per hour). This must be the
internal diameter not the outer diameter (OD) i.e. pipe outer diameter minus twice the
pipe wall thickness.
For example:
If you do not have any suitable monitoring points you will need to drill (tap of ¾” BSP pipe
thread) a hole in the piping of between 25mm and 30mm in diameter to seat the conical
Pipe ID
Pipe OD
Wall Thickness

OMGEM5KN4 GEM5000 gas analyser
Page 50 Copyright Geotech
fitting on the anemometer (which is roughly between 20mm to 34mm). When not in use
the hole can be re-sealed with a ¾” BSP male bung.
Note: When the anemometer is not in use the conical fitting should be placed over
the probe to protect it.
The anemometer must fit centrally (the conical fitting must be set on the probe to half the
pipe ID before insertion). The arrow on the tip of the probe must point in the direction of
the gas flow.
Note: Use the thumb screw to help align the direction of the probe into the gas
stream.
Flow readings are most accurate when there is laminar flow (not turbulent). Turbulence
can be caused by a change in pipe direction or restriction. Ideally, upstream you want at
least 20 times the pipe ID along the length of the pipe without restriction or bend.
Downstream, you want at least five times the pipe ID along the length of the pipe i.e. for a
100mm ID you need 2000mm of clear pipe upstream, 500mm downstream.
Example to show anemometer fitting into the sample point:
Instructions for use:
1) Attach the anemometer to ‘Connector C’ (refer to section 5.3 – Instrument
connection points).
2) Place the anemometer into the pipe (sample point) ready to take the reading.
3) To take a flow measurement when using an anemometer, follow the instructions
displayed on the analyser. When the reading has stabilised press the ‘Enter’ key to
store the reading.

Anemometer cleaning instructions:
General handling tips:
Protect the probes against severe vibration.
Do not kink the connector cable (risk of cable breakage).
Never allow hard objects to contact rotating impellers.
Always carry out probe cleaning according to the cleaning instructions.
Never immerse probes in solvent.
Never blow probes through with compressed air.
Allow hot probes to cool slowly, never cool by plunging them in cold water etc.
Cleaning instructions:
Instrument and probe must be switched off or disconnected prior to cleaning.
Vane probes:
As the probes are highly sensitive measuring instruments, they must be cleaned with
great care.
Fibres or other foreign bodies can be carefully removed with fine tweezers. When
doing so, take care not to bend or otherwise damage the vanes or the spindle.
The adjustment of the bearing screws must never be changed. This can result in an
erroneous measurement.
Never allow hard objects to contact rotating impellers.
Cleaning agents that extract the plasticizer from the plastic are never to be used for
plastic probes (practically all solvents).
Cleaning the probes – best practice:
Note: Use soapy water.
Cleaning example:
1) Carefully, swish the top part of the impeller back and forth in clean soapy water for
approximately 10 minutes. Then swish the top part of the impeller back and forth in
clean soapy water. If soapy water is used as a cleaning agent it is advisable to wash
out the soap solution thoroughly with distilled water.
2) After cleaning the probe, rub it dry with a clean, dry cloth.

8.7 How to use a pitot tube (optional)
The GEM5000 gas analyser enables the site engineer to take gas measurements using a
pitot tube. The pitot tube is used for gas extraction systems and the pressure readings
are taken in mbar. Gas flow is calculated in the analyser in m3/hr (metres cubed per
hour).
Example of a pitot tube
Fitting a pitot tube to the analyser:
1) It is important to seat the pitot tube into the monitoring point with the tip facing into
the gas flow. The pitot tube should also be housed half way down the monitoring
pipe. (Please refer to the anemometer instructions, which detail how to calculate the
pipe diameter correctly).
2) Make sure that the sample tubing attached to the pitot tube fits correctly.
3) Attach the sample tube from the top connection of the pitot tube to the ‘blue port’
(the differential port) on the analyser making sure that the gas port connector secure
into place.
4) Attach the sample tube from the side of the pitot tube to the ‘white port’ (inlet
port/static pressure port) on the analyser making sure that the gas port connector
secures into place.
5) House the pitot gland correctly onto the monitoring point.
6) When taking a gas reading and flow measurement follow the instruction as displayed
on the front of the instrument.
Note: Please refer to the following section for a diagram showing how to fit the
tubing to the pitot tube.

8.8 How to use an H2S filter (optional)
8.8.1 Cross gas effects on chemical cells
Measurements of CO are important in landfill management. The GEM5000 analyser
incorporates an improved CO measurement.
Measurements of CO can be affected by two other gases that can be found in landfill gas
– hydrogen and hydrogen sulphide.
To reduce the effect of hydrogen, the GEM5000 analyser uses a technique that is
hydrogen compensated. Hydrogen compensation is achievable up to a level of around
2000ppm. Above this level the CO reading will not be compensated for.
In order to assist the operator the GEM5000 instrument also indicates the level of
hydrogen present as low, medium or high. If a high hydrogen reading is present then the
CO reading may be affected.
The effect of hydrogen sulphide is eliminated by the use of a H2S filter.
CO measurement
The CO measurement is sensitive to hydrogen sulphide. The presence of hydrogen
sulphide can cause the CO reading to elevate (not to be the true value due to the
interfering gas). If the presence of hydrogen sulphide is suspected to be causing false CO
readings, then it is recommended that the external hydrogen sulphide filter is used whilst
obtaining the CO measurement.
The H2S filter only needs to be used when you are trying to remove of any possible cross
gas effects H2S might have on other gas channels. Do not use the filter on all boreholes.
When using the H2S filter you will need to increase the gas sample and clean air purge
run-time, as using an H2S filter decreases the response time of the analyser.
Note: There is an internal H
2
S filter incorporated in the chemical cell that removes
the H2S; however this has a limited life span.
The electrochemical cells used to measure H2S and CO do suffer from cross-gas effects.
Such effects are not accurately specified. However, the following table may be useful as
a guide; it represents how many ppm would be read by a cell if 100 ppm of the
interfering gas were applied, with no other cross-contaminates being present in the
sample.

8.8.2 Cross-gas effects on methane, carbon dioxide and oxygen
Methane is measured using dual beam infrared absorption. Analysers are calibrated using
certified methane mixtures and will give correct readings provided there are no other
hydrocarbon gases present within the sample (e.g. ethane, propane, butane, etc). If
there are other hydrocarbons present, the methane reading will be elevated (never
lower) than the actual methane concentration being monitored.
The extent to which the methane reading is affected depends upon the concentration of
the methane in the sample and the concentration of the other hydrocarbons. The effect
is totally non-linear and difficult to predict.
Note: The effect can be reduced by using an H
2
S filter as it can reduce higher
order hydrocarbons. When using the H2S filter you will need to increase the
gas sample and clean air purge run-time, as using an H2S filter increases the
response time of the analyser.
Carbon dioxide is measured by infrared absorption at a wavelength specific to carbon
dioxide. Therefore, the carbon dioxide reading will not be affected by any other gases
usually found on landfill sites.
The oxygen sensor is a galvanic cell type and suffers virtually no influence from CO2, CO,
H2S, NO2, SO2 or H2, unlike many other types of oxygen cell.
The infrared sensors will not be ‘poisoned’ by other hydrocarbons and will revert to
normal operation as soon as the gas sample has been ‘purged’.

Note: When onsite the site engineer must have an unmodified water trap assembly
in addition to the modified water trap with a H2S filter in order to take
readings with and without a filter.
1) Once the H2S filter is fitted follow the instructions as detailed on the front of the gas
analyser displayed when taking readings using a H2S filter.
Note: This is only for analysers fitted with the CO compensated cell.
Fitting a pitot tube to a sample point when using an H2S filter:
2) Make sure the water trap filter is fitted as close as possible to the pitot tube. This
will help protect and trap moisture before it reaches the H2S filter. Make sure that
the water trap filter is clean and dry.
3) Attach the sample tubing into the analyser.
4) To take flow readings using a pitot tube, please follow the instructions displayed on
the front of the instrument. The user will be prompted to complete each step and
should follow the instructions on screen.
Note: It is important to fit the pitot tube central and parallel with the pipe.

8.9 How to use a temperature probe (optional)
The temperature probe enables the site engineer to measure the temperature of the gas
within a sample point. The GEM5000 gas analyser uses the temperature of the gas to give
more accurate flow measurement readings as part of the instrument calculation.
GEM5000 & temperature probe
Instructions for use:
1) The temperature probe reading is taken along with the gas measurement reading.
2) The analyser must be at the ‘Main Gas Read Screen’.
3) Attach the temperature probe to ‘connector B’ (refer to section 5.3 – Instrument
connections points).
4) Insert the temperature probe into the sample point (borehole) at the same time as
you attach the sample tube to the sample point (two sample points are required for
the borehole).
5) Follow the instructions on the front of the instrument when taking your gas and
measurement reading.
6) At the point in which the operator presses ‘Enter’ to store the gas reading the
temperature is recorded.
Note: Temperature probe readings can be analysed further when downloaded
to Gas Analyser Manager (GAM).
8.10 How to identify a borehole using the GPS feature (optional)

9.0 Calibration
9.1 Calibration introduction
The GEM5000 gas analyser is carefully calibrated at manufacture and when returned for
service. However, it is sometimes desirable to be able to carry out a calibration process
between services.
This section outlines the correct procedures to enable the site engineer to field calibrate
the gas analyser.
Note: This does not replace the factory service and calibration. If this calibration is
completed incorrectly it may decrease the accuracy of the gas analyser.
CH
4, CO2
and O2 can be measured by GEM5000 gas analyser as standard; these channels
can be user calibrated. The analysers have other gas channel options that are specified at
manufacture; these too can be calibrated. This section will describe in detail how to
calibrate the three standard gas channels plus the CO channel.
The GEM5000 instrument can have a H2 compensated CO channel. This option requires
that H2 is used in the calibration process and is also set out within this section.
For the other gas channel options contact Geotech for advice.
Two important terms that are used within this section are ‘Zero’ and ‘Span’.
Zero: The point at which the gas analyser is calibrated when there is none of the target
gases present.
Span: The point at which the gas analyser is calibrated when a known quantity of the
target gas is present.
9.2 Frequency of calibration – best practice
The GEM5000 gas analysers can be checked against a known concentration of gas, to give
confidence that the analyser is operating as expected at the time and conditions in which it
is being used.
It is recommended that the instrument is regularly serviced and calibrated by Geotech in
accordance with the due date on the instrument.
When defining the frequency of user calibration, the following are factors to be considered:
The frequency of use of the analyser. (daily?/monthly?)
The level of confidence and accuracy required for readings to be taken.
Historical user calibration data.
Site specific requirements or conditions.
Historical understanding of expected readings on site.
Zeroing of the gas analyser should be undertaken at the start of each day’s monitoring.
Use historical data to drive your frequency of calibration.
If there is no historical data a good starting point for a daily monitoring round is
performing a calibration once every week or every other week.
The results of the calibrations will need to be recorded to monitor over time whether the
frequency of calibration needs to be increased or decreased relative to the confidence
required.
Page 62
OMGEM5KN4 GEM5000 gas analyser
Page 62 Copyright Geotech
The confidence required will be driven by the site specific / user requirements.
When undertaking the monitoring with an understanding of the history of the gas levels of
that site, a calibration check could be triggered if the readings measured are different to
what is expected.
Note: For assistance please contact Technical Support at Geotech on +44(0)1926
338111
9.3 Calibration gases
User calibration of a gas analyser will greatly improve the data accuracy in the range of
the calibration gases used. This may cause less accurate readings of concentrations
outside this calibrated range. Users should select the correct calibration gas for the
expected gas levels on their particular application.
To improve calibration at lower levels requires the use of gas mixtures 1 and 2.
To improve higher levels use gas mixture 3.
For standard CO only 100ppm CO gas is needed.
For CO (H2 compensated) both CO 100ppm and H2 1000ppm gases are needed.
The following table indicates the different gas mixture canisters used for calibration:

Calibration targets for gas cells are dependent on the gas/range and type of cell fitted.
Contact Technical Support for assistance.
These are for general use but other gas concentrations can be used.
Note: The above gases and most other gas concentrations can be supplied by
Geotech. For further information please contact Sales on +44(0)1926 338111
or email [email protected].
Warning
Calibration gases can be dangerous.
For each gas used the appropriate material safety data sheet
must be read and understood before proceeding.

9.4 Calibration set-up
Warning
Do NOT attach the gas supply to the gas analyser before
putting the analyser into the ‘Gas Check’ screen. Select
‘Check Spans’ from the ‘Operation Settings’ menu.
The regulator supplied with the calibration kit has been configured to deliver a fixed flow.
As the regulator’s flow is factory set, it only requires a few turns to open, no adjustment is
necessary.
Warning
Exhaust port
When the gas analyser is being calibrated, there are two
possible exits for the gas, via the usual manner out of the
exhaust (yellow) port of the analyser or in cases of overpressurisation the 1/16” port on the red pressure relief valve
located on the regulator.
It is recommended that both ports have exhaust tubing
attached.
The exhaust tubing must emerge in a well-ventilated area.
Ensure there are no leaks in the tubing and connections.
The calibration of the gas analyser should be carried out in a
safe area with all necessary precautions taken when using
potentially dangerous, explosive or toxic gases.
Note: There is also potential for gas to expel from the internal flow (blue) port of the
gas analyser (applies to the GA5000 only).
9.5 Calibration equipment
The diagram below displays the regulator and tubing equipment for user calibration:

10.0 Problem solving
This section outlines various warning and error messages which the operator may receive
during general operation of the instrument. For further assistance please contact Technical
Support at Geotech on +44(0)1926 338111 or email [email protected].
11.0 Warning and error display
When switched on the instrument will perform a pre-determined self-test sequence taking
approximately 15 seconds. During this time many of the instrument’s working parameters
and settings are checked.
If any operational parameters are out of specification or the pre-programmed
recommended calibration/service date has passed, errors or warnings may be displayed.
Use the ‘Scroll up’ and ‘Scroll down’ keys to move through the list if required.
Only three warnings/errors can be displayed at any time.
To ascertain if more errors have occurred use ‘Key 8’ – Scroll down’ and ‘Key 2’ - Scroll up’
through the list.
Warnings displayed:
All warnings displayed will be prefixed by the word WARNING followed by a relevant
description.
There are two types of warning that may be displayed:
1. General warnings that may not affect the instrument’s function and those where the
self-test has detected a function that is outside the usual programmed operating
criteria, e.g. battery charge low, memory nearly full.
2. Operational parameters that could affect the performance of the analyser: Cell out of
calibration, CH4 out of calibration, CO2 out of calibration.
The most likely reason for the errors is either an incorrect user calibration or sensor
failure. If an incorrect user calibration has caused the warning it should be correctable by
way of returning the instrument to factory settings, zeroing or carrying out a user
calibration as necessary for the relevant function.

12.0 Service
The GEM5000 gas analyser should be regularly serviced to ensure correct and accurate
operation. Geotech recommends a service and recalibration every 6 months.
The GEM5000 range is ATEX certified for use in potentially explosive areas. As such it should
be serviced only by qualified engineers. Failure to observe this will result in the warranty
becoming invalid and could invalidate the ATEX certification.
Warning
If the GEM5000 is serviced by unqualified engineers the ATEX
certification may be invalidated and the instrument may be unsafe
for use in a potentially explosive atmosphere.
User serviceable parts:
There are no user serviceable parts inside the instrument.
The following parts can be user serviced:
In-line water filter
This should be regularly inspected for obstructions, moisture
or damage and changed if needed. The instrument should
never be operated without the in-line water filter as this
may result in water entering the instrument.
Sample tubing
Always ensure that sample tubes are not contaminated or
damaged.
Gas port connectors
Periodically check that the O-rings on the gas port
connectors are not damaged. A damaged O-ring can let air
into the sample gas and result in incorrect readings. If the
O-ring is damaged the complete gas port connector should
be replaced.
H2S filter material
When the filter material changes colour to a light grey colour
the filter should be replaced.

sufficientemente addestrato negli aspetti della sicurezza relativi
all’uso di H2S e altri gas nocivi. In particolare nel caso di gas
pericolosi, quelli scaricati dall’analizzatore devono essere convogliati
in un’area in cui lo scaricotale operazione possa essere effettuatao in
condizioni di sicurezza. È possibile che lo strumento scarichi gas

pericolosi anche durante lo spurgoquando viene utilizzato per
spurgare con aria pulita.
Prassi ottimali
Nel recarsi al luogo di utilizzo, collocare l'analizzatore di gas nell’abitacolo del veicolo,
non nel bagagliaio, dove potrebbe essere soggetto a estremi di temperatura e
danneggiarsi per eventuali urti. Non appoggiare l’analizzatore di gas contro superfici calde
(ad es. tubo di aspirazione del gas, carrozzeria di un’autovettura o interno di
un’autovettura incustodita in estate), perché ciò fa aumentare la temperatura
dell’analizzatore di gas e può falsare le letture.
Negli spostamenti nell'area di utilizzo dell'analizzatore di gas, proteggerlo dalla luce
diretta del sole e dagli scrosci di pioggia.
Usare sempre il sifone per lo scarico della condensa!. Se il sifone si allaga, cambiare il
filtro e controllare che tutti i tubi siano liberi dalla condensa prima di riutilizzarlo
Nota: se lo scarico di un analizzatore di gas serie GA5000 è collegato ad un
sistema pressurizzato, ciò fa uscire un flusso di gas dall’entrata.
Taratura
Avvertenza
I gas di taratura possono essere pericolosi.
Per ciascun gas da utilizzare, leggere preventivamente la
relativa scheda tecnica di sicurezza, accertandosi di
comprenderne il contenuto.
Il regolatore fornito col kit di taratura è stato configurato per permettere l’erogazione di un
flusso fisso.
Dato che il flusso del regolatore è impostato in fabbrica, può essere aperto con una
semplice rotazione, senza effettuare regolazioni.
Avvertenza
Luce di scarico
Durante la taratura dell’analizzatore, vi sono due possibili
uscite per il gas: come di norma dalla luce di scarico
(gialla)dell’analizzatore o, in caso di sovrapressione, dalla
luce di 1/16” della valvola limitatrice di pressione rossa
situata sul regolatore.
Si raccomanda che entrambe le luci siano dotate di tubi di
scarico,
che devono sboccare in un’area ben ventilata. Controllare
che i tubi e i raccordi non presentino perdite.
La taratura dell’analizzatore di gas va eseguita in un’area
idonea, adottando tutte le precauzioni necessarie per l’utilizzo
di gas potenzialmente pericolosi, esplosivi o tossici.
Nota: è possibile anche che il gas esca dall’uscita del flusso interno (blu)
dell’analizzatore di gas (vale solo per GA5000).

Manutenzione
Gli analizzatori di gas della serie 5000 devono essere sottoposti a regolare controllo di
manutenzione per accertare che il funzionamento sia corretto e preciso. Geotech
raccomanda che la manutenzione e la taratura siano effettuate ogni 6 mesi.
Gli analizzatori di gas della serie 5000 hanno la certificazione ATEX per l’utilizzo in aree
potenzialmente esplosive. In quanto tali, la loro manutenzione deve essere affidata
esclusivamente a tecnici qualificati. La mancata osservanza di questa regola invalida la
garanzia ed eventualmente anche la certificazione ATEX.
Avvertenza
Se la manutenzione dell’analizzatore di gas viene
effettuata da tecnici non qualificati, la certificazione ATEX
può venirne compromessa, pregiudicando così l’utilizzo in
condizioni di sicurezza dello strumento in un’atmosfera
potenzialmente esplosiva.
Parti riparabili dall’utente:
Non vi sono parti riparabili dall’utente all’interno dello strumento.
Le parti seguenti possono essere riparate:
Filtro acqua in linea
Va controllato regolarmente per evidenziare eventuali
ostruzioni, condensa o danneggiamenti e sostituito se
necessario. Lo strumento non va mai usato senza il filtro
in linea, per evitare possibili infiltrazioni dperché vi
entrerebbe l’acqua.
Tubi di campionamento
Controllare sempre che i tubi di campionamento non
siano contaminati o danneggiati.
Raccordi del gas
Controllare periodicamente che i gommini O-ring dei
raccordi del gas non siano danneggiati. Se danneggiati,
gli O-ring lasciano entrare aria nei tubi di
campionamento, sfalsando le letture. Se l’O-ring risulta
danneggiato, è necessario sostituire tutto il raccordo.
Materiale del filtro H2S
Quando il materiale del filtro cambia colore e diventa
grigio chiaro, il filtro va sostituito.

MCERTS
MCERTS ist das Monitoring Certification Scheme (Zertifizierungsprogramm für
Überwachungsgeräte) der britischen Umweltagentur. Das Programm bietet einen Rahmen,
in dem Umgebungsmessungen gemäß den Qualitätsanforderungen der Agentur
durchgeführt werden können. Es umfasst eine Reihe von Überwachungs-, Probenahmeund Prüfaufgaben.
Das Instrument GEM5000 ist nur MCERTS-zertifiziert, falls:
Das MCERTS-Logo nach dem erstmaligen Einschalten auf dem Bildschirm erscheint.
Hinweis: MCERTS - Bei diesem Gerät wurden keine Störempfindlichkeitsprüfungen
mit Schwefelwasserstoff durchgeführt. Daher sollten Benutzer wissen, ob
H2S vor Ort vorhanden ist, da dies eine Störwirkung zur Folge haben
könnte.
MCERTS fördert das öffentliche Vertrauen in Überwachungsdaten und liefert der Industrie
einen erprobten Rahmen zur Auswahl von Überwachungssystemen und -dienstleistungen,
Page 85

die die Leistungsanforderungen der Umweltagentur erfüllen.
Die britische Umweltagentur hat MCERTS (Monitoring Certification Scheme) initiiert, um
hochwertige Umweltmessungen bereitzustellen. Das MCERTS
Produktzertifizierungsprogramm ermöglicht die Zertifizierung von Produkten gemäß den
Leistungsstandards der Umweltagentur basierend auf den entsprechenden CEN-, ISO- und
nationalen Normen.
MCERTS-zertifizierte Geräte wurden durch eine unabhängige Stelle geprüft, um zu
gewährleisten, dass bestimmte Leistungsanforderungen erfüllt werden. Darüber hinaus
wird der Hersteller eines MCERTS-Produkts regelmäßig geprüft, um zu gewährleisten, dass
die Leistungsanforderungen der Zertifizierung durchgehend erfüllt werden.
Die Gasanalysatoren der 5000er Serie wurden gemäß Version 3.1 der
„Leistungsanforderungen für tragbare Emissionsüberwachungssysteme“ zertifiziert.
Akku und Aufladen
Bei dem Akku, der in den Gasanalysatoren der 5000er Serie verwendet wird, handelt es
sich um einen Nickel-Metallhydrid-Akku, der als Akkupack aus sechs einzelnen Zellen
hergestellt wird. Dieser Akkutyp ist weniger stark für den Memoryeffekt anfällig als NickelKadmium-Akkus. Trotzdem wird davon abgeraten, das Gerät mit kleinen Ladungen
nachzuladen.
Das Ladegerät sollte nur getrennt werden, wenn komplette Ladung angezeigt wird.
Warnhinweise
Das Akkuladegerät ist NICHT in der ATEX-Zertifizierung
enthalten. Der Akku darf nur in einem sicheren Bereich
aufgeladen werden.
Das Akkuladegerät ist intelligent und zeigt an, wenn die Einheit aufgeladen wird bzw. wenn
sie vollständig aufgeladen ist.
Das Gerät darf NUR mit dem mitgelieferten Akkuladegerät aufgeladen werden. Das
Akkuladegerät ist nur für den Gebrauch in Innenräumen vorgesehen. Bitte sorgen Sie für
ausreichende Belüftung während des Aufladens.
Ladegerät: Eingangsspannung: 100-240 V AC +/- 10 %

Reinigungsanweisungen
Ve vrwenden Sie KEINE Reinigungsmittel zum Reinigen des Analysegeräts oder
Akkuladegeräts, da sie die sichere Verwendung dieser Geräte beeinträchtigen können.
Good Practice beim Ablesen
Warnhinweise
Das Einatmen von Schwefelwasserstoffgas (H2S) oder anderer
Page 86
OMGEM5KN4 GEM5000 gas analyser
Page 86 Copyright Geotech
schädlicher Gase kann tödlich sein. Es liegt in der
Verantwortung des Benutzers sicherzustellen, dass er/sie
angemessen über die Sicherheitsaspekte beim Einsatz von H2S
und anderer schädlicher Gase geschult ist. Vor allem beim
Einsatz gefährlicher Gase muss das vom Analysator
ausströmende Gas in einen Bereich geleitet werden, in dem das
Gas sicher abgeführt werden kann. Gefährliches Gas kann
ebenso vom Gerät ausgestossen werden, wenn es mit sauberer
Luft ausgeblasen wird.
Good Practice
Transportieren Sie den Gasanalysator im Inneren des Fahrzeugs an den Einsatzort -
nicht auf der Ladefläche, wo er Temperaturschwankungen und möglichen Stößen
ausgeliefert ist. Platzieren Sie den Gasanalysator nicht direkt an oder auf etwas
Heißem (z. B. Gasleitung, Karosserie oder in einem unbeaufsichtigten Auto während
des Sommers), da dies einen Temperaturanstieg im Gasanalysator verursacht und zu
fehlerhaften Messwerten führen kann.
Schützen Sie den Gasanalysator am Einsatzort vor starkem, direktem Sonnenlicht
und starkem Regen.
Verwenden Sie stets den Wasserabscheider! Wenn der Wasserabscheider überschwemmt
wird, tauschen Sie den Filter aus, und stellen Sie sicher, dass alle Schläuche frei von
Feuchtigkeit sind, bevor Sie sie erneut verwenden.
Hinweis: Wenn der Auslass eines Gasanalysators der Serie GA5000 an ein
druckbeaufschlagtes System angeschlossen ist, dann führt dies zu einem
Gasstrom aus dem Einlassstromanschluss.
Kalibrieren
Warnhinweise
Eichgase können gefährlich sein.
Vor dem Verfahren müssen die
Materialsicherheitsdatenblätter aller verwendeten Gase
gelesen und verstanden werden.
Der mit dem Kalibrierset gelieferte Regulator wurde so konfiguriert, dass er einen
unveränderlichen Durchfluss liefert.
Da der Durchfluss des Regulators werkseitig eingestellt ist, lässt der Regulator sich mit nur
wenigen Drehungen öffnen; eine Einstellung ist nicht erforderlich.
Warnhinweise
Austrittsöffnung
Wenn der Gasanalysator kalibriert wird, gibt es zwei
mögliche Ausgänge für das Gas: auf die übliche Art über
die Austrittsöffnung (gelb) des Analysators oder bei
Überdruck über die 1/16”Öffnung des roten
Druckentlastungsventils, das sich am Regler befindet.
Für beide Öffnungen wird das Anbringen von
Auslassrohrleitungen empfohlen.
Die Auslassrohrleitungen müssen in einen gut belüfteten
Bereich führen. Stellen Sie sicher, dass es in den
Page 87
GEM5000 gas analyser OMGEM5KN4
Copyright Geotech Page 87
Rohrleitungen und an den Verbindungen keine
Undichtigkeiten gibt.
Das Kalibrieren des Gasanalysators muss in einem
sicheren Bereich unter Anwendung aller notwendigen
Sicherheitsvorkehrungen durchgeführt werden, wenn
möglicherweise gefährliche, explosive oder toxische Gase
eingesetzt werden.
Hinweis: Es besteht außerdem die Möglichkeit, dass Gas aus dem internen
Strömungsanschluss (blau) des Gasanalysators ausgestoßen wird (gilt nur
für GA5000).
Wartung
Die Gasanalysatoren der 5000er Serie müssen regelmäßig gewartet werden, um den
korrekten und genauen Betrieb zu gewährleisten. Geotech empfiehlt ein Wartungs- und
Neukalibrierungsintervall von 6 Monaten.
Die Gasanalysatoren der 5000er Serie sind für den Einsatz in explosionsgefährdeten
Bereichen ATEX-zertifiziert. Daher dürfen sie nur von qualifizierten Technikern gewartet
werden. Im Falle der Nichtbefolgung erlischt die Garantie, und die ATEX-Zertifizierung
kann ihre Gültigkeit verlieren.
Warnhinweise
Falls derGasanalysator von unqualifizierten Technikern
gewartet wird, kann die ATEX-Zertifizierung ihre
Gültigkeit verlieren, und das Gerät ist möglicherweise
für den Einsatz in einer explosionsgefährdeten
Atmosphäre nicht mehr sicher.
Teile, die durch den Benutzer gewartet werden können:
Im Gerät gibt es keine Teile, die durch den Benutzer gewartet werden können.
Die folgenden Teile können durch den Benutzer gewartet werden:
Wasserleitungsfilter
Er muss regelmäßig auf Verstopfungen, Feuchtigkeit
bzw. Beschädigungen untersucht und, falls erforderlich,
ausgetauscht werden. Das Gerät darf nie ohne den
Wasserleitungsfilter betrieben werden, da dies dazu
führen könnte, dass Wasser in das Gerät eindringt.
Probenrohrleitungen
Stellen Sie stets sicher, dass die Probenrohrleitungen
weder verunreinigt noch beschädigt sind.
Gasausgangsanschlüsse
Prüfen Sie periodisch, ob die O-Ringe an den
Gasausgangsanschlüssen beschädigt sind. Durch einen
beschädigten O-Ring kann Luft in das Messgas
eindringen und zu falschen Messwerten führen. Falls der
O-Ring beschädigt ist, muss der gesamte
Gasausgangsanschluss ausgetauscht werden.
H2S Filtermaterial
Sobald die Farbe des Filtermaterials leicht grau wird,
muss der Filter ausgetauscht werden.

MCERTS
MCERTS est le programme de certification de la surveillance, établi par l'agence
britannique à l'Environnement. Ce programme forme le cadre dans lequel des mesures
environnementales peuvent être effectuées conformément aux exigences de qualité de
l'agence. Il couvre un ensemble d'activités de surveillance, d'échantillonnage et
d'inspection.
L'instrument GEM5000 n'est certifié MCERTS que si :
Le logo MCERTS s'affiche à l'écran après la mise sous tension de l'instrument.
Remarque : MCERTS - Cet instrument n'a pas fait l'objet de tests de sensibilité
croisée utilisant le sulfure d'hydrogène. Par conséquent, les
utilisateurs doivent être conscients qu'en cas de présence de H2S sur
les sites, il peut y avoir un effet d'interférence.
Le programme MCERTS contribue à renforcer la confiance du public vis-à-vis des données
Page 94

Page 94 Copyright Geotech
de surveillance et donne à l'industrie des paramètres sûrs pour le choix de systèmes et de
services de surveillance répondant aux exigences de performance de l'agence.
L'agence à l'Environnement a établi ce programme MCERTS (Monitoring Certification
Scheme) pour fournir des valeurs mesurées environnementales de qualité. La certification
MCERTS concerne les produits aux normes de performance de l'agence à l'Environnement,
sur la base des normes nationales, CEN et ISO pertinentes.
Les instruments certifiés MCERTS sont testés par un organisme indépendant pour assurer
leur conformité à certaines exigences de performance. En outre, le fabricant de produits
MCERTS fait l'objet d'audits réguliers pour s'assurer du respect continu des exigences de
performance de ses produits aux fins de certification.
Les analyseurs de gaz de la série 5000 ont été certifiés conformément à la version 3.1 des
« Normes de performance des systèmes portatifs de surveillance des émissions de
substances dans l'atmosphère ».
Batterie et mise en charge
Les analyseurs de gaz de la série 5000 sont dotés d'une batterie au nickel-métal-hydrure,
à six cellules individuelles intégrées. Ce type de batterie n'est pas aussi sensible à « l'effet
de mémoire » qui affecte les capacités des piles au nickel cadmium. Il est cependant
déconseillé de recharger la batterie par à-coups.
Débrancher le chargeur uniquement après indication de pleine charge.
Avertissement
Le chargeur de batterie n'est PAS couvert par la
certification Ex. La batterie ne doit être chargée que
dans un endroit sûr.
Le chargeur de batterie est intelligent et indique que la batterie est en cours de
chargement ou chargée.
La batterie doit être chargée UNIQUEMENT à l'aide du chargeur fourni avec l'instrument.
Le chargeur de batterie doit être utilisé uniquement à l'intérieur. Veiller à assurer une
ventilation adéquate pendant le chargement.
Chargeur : Tension d'entrée : 100-240 V CA +/- 10 %
Fréquence d'entrée : 50-60 Hz +/- 10 %
Courant d'entrée : 0,4 A@100 V CA.. 0,2 A@240 V CA
Tension de sortie : 10,1 V CC max
Courant de sortie : 1,5 A max
Remarque : connecter le chargeur à l'alimentation secteur à l'aide de l'adaptateur
approprié. Contacter le fabricant pour de plus amples informations.

Bonnes pratiques lors des mesures
Avertissement
L'inhalation de sulfure d'hydrogène (H2S) ou d'autres gaz
dangereux peut entraîner la mort. Il incombe à l'utilisateur
de s'assurer qu'il a reçu la formation adaptée aux aspects
sécurité de l'utilisation de H2S et d'autres gaz dangereux. En
particulier, lors de l'utilisation de gaz dangereux, les gaz en
sortie de l'analyseur doivent être évacués dans une zone où
ils ne présentent aucun danger. Des gaz dangereux peuvent
aussi être expulsés de l'instrument lors d'une purge à l'air
propre.
Bonnes pratiques
Lors d'un déplacement vers un site d'utilisation, transporter l'instrument dans
l'habitacle du véhicule, et non pas dans le coffre où il pourrait être soumis à des
températures extrêmes, voire à des chocs risquant de l'endommager. Ne pas placer
l'analyseur de gaz contre des surfaces chaudes (conduite d'extraction de gaz,
carrosserie d'une voiture ou voiture laissée sans surveillance en été, par exemple)
car les effets de la chaleur sur l'analyseur risquent d'entraîner des valeurs mesurées
incorrectes.
Lors du déplacement sur site, protéger l'analyseur de gaz de la lumière solaire
directe et des fortes intempéries.
Toujours utiliser le piège à eau ! Si le piège à eau déborde, changer le filtre et vérifier que
tous les tuyaux ne présentent aucune trace d'humidité avant toute utilisation.
Remarque : si l'évacuation d'un analyseur de gaz de la série GA5000 est connectée
à un système sous pression, un flux de gaz s'échappera du port de
débit d'entrée.
Étalonnage
Avertissement
Les gaz d'étalonnage peuvent être dangereux.
Pour chaque gaz utilisé, il convient de lire et de
comprendre la fiche de données de sécurité
correspondante avant de poursuivre.
Le régulateur fourni avec le kit d'étalonnage a été configuré pour assurer un débit fixe.
Le débit du régulateur étant réglé en usine, il ne faut que quelques tours pour l'ouvrir et
aucun réglage n'est nécessaire.
Avertissement
Orifice d'évacuation
Lors de l'étalonnage de l'analyseur de gaz, le gaz peut être
évacué par deux orifices : par l'orifice d'évacuation normal
(jaune) de l'analyseur ou, dans les cas de surpression, par
Page 96
OMGEM5KN4 GEM5000 gas analyser
Page 96 Copyright Geotech
l'orifice de 1/16 de pouce de la soupape de surpression
rouge située sur le régulateur.
Il est recommandé de raccorder des tuyaux d'évacuation à
ces deux orifices.
Le tuyau d'évacuation doit laisser les gaz s'échapper dans
un endroit bien ventilé. Vérifier que les tuyaux et les
raccords ne présentent aucune fuite.
L'étalonnage de l'analyseur de gaz doit s'effectuer dans un
endroit sûr, en observant toutes les précautions
nécessaires en présence de gaz potentiellement
dangereux, explosifs ou toxiques.
Remarque : le gaz peut être aussi expulsé au niveau du port de débit interne (bleu)
de l'analyseur de gaz (applicable uniquement au modèle GA5000).
Entretien
Pour un fonctionnement correct et précis, l'analyseur de gaz de la série 5000 doit faire
l'objet d'un entretien régulier. Geotech recommande un entretien et un réétalonnage tous
les 6 mois.
Les analyseurs de gaz de la série 5000 sont certifiés ATEX pour l'utilisation en
environnements potentiellement explosifs. En conséquence, leur entretien doit être
effectué uniquement par des techniciens qualifiés. Le non-respect de cette exigence
entraînera l'annulation de la garantie, voire de la certification ATEX.
Avertissement
Si l'analyseur de gaz fait l'objet d'un entretien par des
techniciens non qualifiés, la certification ATEX risque
d'être annulée et l'appareil peut ne pas être sûr en cas
d'utilisation dans un environnement potentiellement
explosif.
Composants pouvant faire l'objet d'un entretien par l'utilisateur :
L'appareil ne contient aucun composant interne pouvant faire l'objet d'un entretien par
l'utilisateur.
Les composants suivants peuvent faire l'objet d'un entretien par l'utilisateur :
Filtre à eau en ligne
Contrôler ce filtre régulièrement pour rechercher la
présence d'obstructions, d'humidité ou de dommages
; le remplacer si besoin est. L'appareil ne doit jamais
être utilisé sans le filtre à eau en ligne pour prévenir la
pénétration d'eau dans l'appareil.
Tuyau d'échantillonnage
Toujours vérifier que les tuyaux d'échantillonnage ne
sont ni contaminés ni endommagés.
Raccords d'orifices de gaz
Contrôler périodiquement les joints toriques des
raccords d'orifices de gaz pour s'assurer qu'ils ne sont
pas endommagés. Un joint torique endommagé peut
laisser passer l'air dans le gaz d'échantillonnage et
entraîner des valeurs mesurées incorrectes. Remplacer
le raccord complet si le joint torique est endommagé.
