Standards information and hydrogen safety

English

Standards information and hydrogen safety Before using the Gas-Tec, read and understand the manual in full before use. Make sure the alarm warnings listed in Section XIII of the manual are fully understood. Do not substitute components as this may impair the IP rating, EMC performance and invalidate warranty. Pay careful attention to warnings and instructions displayed on the instrument. Observe site health and safety procedures for gases being monitored and be aware of evacuation procedures. If this product is not working properly, read the operating manual or contact your local authorised Crowcon service centre.

1.1 Standards Changes or modifications not expressly approved by Crowcon could void the user’s authority to operate the equipment and cause safety implications.

1.2 Safety: WARNING: GAS HYDROGEN CYLINDER PRESSURE MUST NOT EXCEED 1800 psi (124 bar) It is important to maintain a supply of full hydrogen cylinders if the Gas-Tec is to be used regularly. See Section IX to check how long the cylinders to be used will last. Hydrogen is not a dangerous gas if released into the air in small quantities. The biggest risk is that hydrogen will build up inside the equipment. Beyond a certain pressure, or rapidly released into air, the gas could ignite. This could cause an explosion. Before Gas-Tec is turned off, check the gas cylinder has been closed off by turning the valve, clockwise, to the ‘OFF’ position.

After this is done, the gas pressure registered will drop gradually. The pump will continue to run until the gas pressure drops to 150 psi. If the valve is left open hydrogen will leak into the enclosed space inside the instrument at 20 ml/minute. In extreme cases a build-up could cause an explosion.

WARNING: USE OF HYDROGEN As with any apparatus using hydrogen stored under high pressure, certain precautions are prudent. These mainly concern the handling and filling of the hydrogen cylinder and are dealt with in section XII. In addition, the detector uses a hydrogen flame and this point should be considered when the instrument is used in situations where the gas concentrations are likely to be dangerously high (above 10,000 ppm).

1.3 Battery change Users may not change the battery of this product: it must be replaced at Crowcon or an approved service centre.

1.4 Charging Use only the charger supplied with the Gas-Tec, or the vehicle charger listed in the accessories section. The unit cannot be turned on while it is being charged.

1.5 Zeroing

Gas-Tec

1.2 Sécurité : AVERTISSEMENT : LA PRESSION DU CYLINDRE D’HYDROGÈNE NE DOIT PAS DÉPASSER 1 800 psi (124 bars) Il est important de tenir à disposition une réserve de cylindres d’hydrogène pleins si le Gas-Tec doit être utilisé régulièrement. Voir la Section IX pour vérifier combien de temps les cylindres à utiliser dureront. L’hydrogène n’est pas un gaz dangereux s’il est libéré dans l’air en petites quantités. Le plus grand risque provient du fait que l’hydrogène peut s’accumuler dans l’équipement. Au-delà d’une certaine pression ou s’il est libéré rapidement dans l’air, le gaz peut s’enflammer. Ceci peut provoquer une explosion. Avant d’éteindre le Gas-Tec, vérifiez que le cylindre de gaz a été verrouillé en tournant la valve dans le sens des aiguilles d’une montre en position d’arrêt (OFF).

The screen (see page 12) will ask if the GasTec is ‘In clean air?’ • Press ‘Yes’ and the Gas-Tec will set the zero at the current level. • Press ‘No’ and the Gas-Tec will set the the zero to the factory zero point.

1.6 Avoid contamination Do not use the equipment without a filter assembly installed. Ensure foreign bodies and moisture do not enter the probe.

S’assurer de bien comprendre les avertissements d’alarme sur la liste en Section XIII du manuel. Ne pas remplacer de composants au risque de compromettre la norme IP, la performance CEM et d’invalider la garantie. Lire avec attention les avertissements et les instructions inscrites sur l’appareil. Respecter les procédures d’hygiène et de sécurité pour les gaz contrôlés et s’informer des procédures de leur évacuation. Si ce produit ne fonctionne pas correctement, lire le manuel de l’utilisateur ou contacter votre centre de service Crowcon local agréé.

1.1 Normes Les changements ou modifications qui n’ont pas explicitement été approuvés par Crowcon pourraient invalider l’autorisation de l’utilisateur à se servir de l’appareil et avoir des implications pour la sécurité

Ceci fait, la pression de gaz mesurée baisse graduellement. La pompe continuera de tourner jusqu’à ce que la pression du gaz baisse à 150 psi. Si la valve est laissée ouverte, de l’hydrogène s’échappera selon un débit de 20 ml/minute dans l’espace fermée situé à l'intérieur de l’instrument. Dans des cas extrêmes, une accumulation peut entraîner une explosion. AVERTISSEMENT : UTILISATION D’HYDROGÈNE Comme avec tous les appareils qui utilisent de l’hydrogène emmagasiné sous haute pression, certaines précautions doivent être prises. Elles concernent principalement la manutention de l’hydrogène et le remplissage du cylindre qui sont traités en Section XII. De plus, le détecteur utilise une flamme d’hydrogène et il faudra tenir compte de ce danger lorsque l’appareil est utilisé dans des situations où les concentrations de gaz peuvent être dangereusement élevées (plus de 10.000 ppm).

1.3 Remplacement de la batterie Les utilisateurs ne doivent pas remplacer la batterie de ce produit : elle doit être remplacée à Crowcon ou dans un centre de service approuvé.

Standards information and hydrogen safety

Después de hacer esto, la presión de gas registrada disminuye gradualmente. La bomba continúa funcionando hasta que la presión del gas baja a 150 psi. Si la válvula se deja abierta, una fuga de hidrógeno penetra en el espacio cerrado del interior del instrumento a 20 ml/minute. En casos extremos, una acumulación de gas podría causar una explosión. ADVERTENCIA: USO DEL HIDRÓGENO Igual que con cualquier aparato que utilice hidrógeno almacenado bajo alta presión, es prudente adoptar ciertas precauciones. Estas se refieren principalmente a la manipulación y llenado del cilindro de hidrógeno y se consideran en la sección XII. Además, el director utiliza una llama de hidrógeno y este punto debe considerarse cuando el instrumento se utiliza en situaciones donde es probable que las concentraciones de gas sean peligrosamente altas (superiores a 10,000 ppm).

1.3 Cambio de la batería Los usuarios no pueden cambiar la batería de este producto: debe ser cambiada en Crowcon o en un centro de servicio aprobado.

1.4 Carga Utilice solamente el cargador suministrado con el Gas-Tec o el cargador de vehículos detallado en la sección de accesorios. La unidad no puede activarse mientras se está cargando.

1.5 Puesta a cero La pantalla (veánse la página 15) preguntará si el Gas-Tec está en ‘¿En aire limpio?’

segnalazioni d’allarme elencate al Capitolo XIII del manuale. Non sostituire componenti delle apparecchiature perché ciò potrebbe compromettere il grado di protezione IP e il livello di prestazione EMC, e invalidare la garanzia. Prestare la massima attenzione alle avvertenze ed istruzioni che appaiono sullo strumento Attenersi alle procedure antinfortunistiche locali per i gas da controllare e tenersi al corrente delle procedure di evacuazione. Se questo apparecchio non dovesse funzionare correttamente, consultare il manuale operativo o contattare il centro assistenza autorizzato Crowcon più vicino.

1.1 Normativa L’apporto di variazioni o modifiche non approvate espressamente da Crowcon potrebbe invalidare il diritto dell'utente all'uso dell'apparecchio con possibili conseguenze sulla sicurezza

1.2 Sicurezza: AVVERTENZA: LA PRESSIONE DELLA BOMBOLA DI GAS IDROGENO NON DEVE SUPERARE I 1800 psi (124 bar) Se il Gas-Tec deve essere usato regolarmente, è importante mantenere una scorta di bombole di idrogeno piene. Per controllare la durata delle bombole da usare, vedere la Sezione IX. L’idrogeno non è un gas pericoloso se viene rilasciato nell’aria in piccole quantità. Il rischio più grande è l’accumulo d’idrogeno all’interno dell’apparecchio. Oltre ad una determinata pressione, o se viene rilasciato rapidamente nell’aria, il gas potrebbe infiammarsi. Questo potrebbe provocare un’esplosione. Prima di spegnere il Gas-Tec, verificare che la bombola del gas sia stata chiusa ruotando la valvola in senso orario sino alla posizione ‘OFF’.

• Pulse ‘Sí‘ y el Gas-Tec ajustará el cero al nivel actual. • Pulse ‘No’ y el Gas-Tec ajustará el cero al punto cero de fábrica.

Dopo di che, il valore di lettura delle pressione del gas scenderà gradualmente. La pompa continuerà a girare sino a quando la pressione del gas non scende a 150 psi. Se si lascia aperta la valvola, l’idrogeno fuoriesce nello spazio racchiuso all’interno dello strumento a 20 ml/minuto. In casi estremi un suo accumulo potrebbe causare un’esplosione.

Gas-Tec ATTENZIONE: USO DELL’IDROGENO Come per qualsiasi apparecchio che fa uso di idrogeno ad alta pressione, occorre osservare determinate precauzioni. Queste riguardano soprattutto il maneggio e il riempimento della bombola dell’idrogeno e sono trattate nel capitolo XII. Inoltre, il rivelatore utilizza una fiamma di idrogeno, e di questo si dovrebbe tener conto quando lo strumento venga usato in situazioni in cui è probabile che le concentrazioni dei gas siano pericolosamente elevate (al di sopra di 10.000 ppm).

1.3 Cambio della batteria Gli utenti non sono autorizzati a cambiare la batteria di questo apparecchio, che deve essere sostituita da Crowcon o da un centro assistenza autorizzato.

1.4 Caricamento Usare solo il caricabatterie fornito con il Gas-Tec, oppure il caricabatterie su veicolo elencato nel capitolo degli accessori. Lo strumento non può essere acceso mentre si sta caricando la batteria.

1.5 Azzeramento La schermata (vedere pagina 16) chiederà se il Gas-Tec è ‘In aria pulita?’ • Se si preme ‘Sì’ il Gas-Tec imposterà lo zero sul livello attuale. • Se si preme ‘No’ il Gas-Tec imposterà lo zero sul valore stabilito in fabbrica.

1.1 Normen

1.4 Opladen

Veranderingen of aanpassingen die niet uitdrukkelijk door Crowcon zijn goedgekeurd kunnen de bevoegdheid van de gebruiker om het apparaat te bedienen ongeldig maken en gevolgen voor de veiligheid hebben.

Gebruik alleen de oplader die bij de Gas-Tec is meegeleverd, of de voertuigoplader die in het hoofdstuk accessoires staat aangegeven. Het apparaat kan niet worden aangezet terwijl het wordt opgeladen.

1.5 Op nul zetten Het scherm (zie pagina 17) zal u vragen of Gas-Tec ‘in schone lucht is’.

1.2 Veiligheid: WAARSCHUWING: DE DRUK VAN DE GASWATERSTOFFLES MAG NIET HOGER ZIJN DAN 124 bar (1800 psi) Het is belangrijk om een voorraad volle waterstofflessen aan te leggen als de GasTec regelmatig wordt gebruikt. Raadpleeg deel IX om te controleren hoe lang de flessen meegaan. Waterstof is niet gevaarlijk als het in kleine hoeveelheden aan de lucht wordt afgelaten. Het grootste risico is dat waterstof zich binnen de apparatuur ophoopt. Met een bepaalde druk, of als het gas snel aan de lucht wordt afgelaten, kan het gas ontbranden. Dit kan een ontploffing veroorzaken. Voordat de Gas-Tec wordt uitgeschakeld, moet u controleren of de gasfles is gesloten door de klep naar rechts, naar OFF te draaien.

Zodra dit is gebeurd, zal de gasdrukwaarde langzaam zakken. De pomp blijft functioneren, totdat de gasdruk is gedaald tot 10,3 bar (150 psi). Als de klep open wordt gelaten, zal de waterstof in de besloten ruimte binnen het instrument lekken met een snelheid van 20 ml/minuut. In extreme gevallen kan een ophoping van waterstof een ontploffing veroorzaken. WAARSCHUWING: GEBRUIK VAN WATERSTOF Net als bij alle andere apparatuur die waterstof gebruiken die onder hoge druk is opgeslagen zijn bepaalde voorzorgsmaatregelen essentieel. Het gaat hier voornamelijk om het hanteren en vullen van de waterstofcilinder. Dit wordt hoofdstuk XII behandeld. Hiernaast gebruikt de detector een waterstofvlam en dit punt moet worden overwogen wanneer het instrument wordt gebruikt in situaties waar de gasconcentraties gevaarlijk hoog kunnen zijn (boven 10.000 ppm).

1.3 Vervangen batterij

Gas-Tec Introduction

Gas-Tec

English

II. Gas-Tec Introduction 2.1 Product description Gas-Tec is a portable gas detector for rapid survey and leak localisation. GPS, data and event logging allow survey teams to pinpoint and report on areas of significant interest. Gas-Tec senses hydrocarbons through the use of flame ionisation detection offering an extremely fast detection speed of less than 2 seconds. Gas-Tec is worn across the body and is supplied with a standard probe. A wide range of other probes and accessories are available (see Sections VIII and XI).

2.2 Flame Ionisation Detection (FID) Flame Ionization Detection (FID) is the fastest, most sensitive and accurate way to detect concentrations of hydrocarbons such as methane, butane or hexane. The FID process uses a hydrogen flame to burn hydrocarbons in an air sample then counts the ions produced by the burnt sample. The instrument then displays an accurate measurement of the concentration of hydrocarbons present in the sample. All samples are destroyed as the measurements are generated. This process takes place in a specially designed chamber.

2.3 Hydrogen Safety Users of the Gas-Tec will need to handle the hydrogen cylinder correctly. A leak from a full cylinder could result in a build-up of gas that could, in extreme cases, cause an explosion. Install the cylinder carefully (Section III.1, page 10) Check the cylinder is secured in place before opening the valve. Tighten the cylinder as tightly as possible by hand. Never use a wrench, hammer, or other tool to open or close the hand wheel. The Gas-Tec LCD display will prompt users through the startup and shutdown procedures ensuring safe use. Gas-Tec will display relevant messages: • Will let the operator know if the gas pressure is too low. • Will prompt the operator to open the valve to allow gas to flow • Will prompt the operator to close the valve during shut-down • Will let the operator know it is safe to power down the Gas-Tec If the gas pressure is too high • Will let the operator know if the gas pressure is too high; • Will prompt the operator to close the valve to allow gas pressure to decrease and disconnect the gas cylinder. 20

Gas-Tec Introduction

The person responsible for providing hydrogen cylinders should read Sections XIII and X.1 of this manual.

2.4 What Gas-Tec detects Most users will be using Gas-Tec to detect methane. The instrument is also sensitive to other hydrocarbon gases such as propane. If other hydrocarbon gases are present, the Gas-Tec reading will reflect their presence. The Gas-Tec’s response to other gases differs from the reading shown for methane. Correction factors for some common hydrocarbons are shown below: Gas detected

III Operation Prior to START UP... 3.1 Getting ready Make these checks before start-up: • The battery of the Gas-Tec should be charged, indicated by the GREEN LED (see Section X.4, page 40 for more details). • a probe must be connected with a filter inline • gas pressure in the hydrogen cylinder must be greater than 150 psi (see Section X.1, for more details) and at a maximum pressure of 1800 psi. The Gas-Tec will not work if the battery is not sufficiently charged or the pressure in the hydrogen cylinder is too low. Using the LCD display, these requirements can be checked once the machine has been switched on. However, there are a few steps to complete prior to this.

Attach the gas cylinder: Set the hydrogen cylinder in place by pushing the bottom into the ‘toe’ of the Gas-Tec (below left). Position it so that the cylinder and Gas-Tec connections line up. Then attach the cylinder to the Gas-Tec by screwing the nut until tight.

Secure cylinder

Attach the probe: To attach the probe, push the coupling on the end of the probe assembly into the probe connector at the base of the Gas-Tec. It will ‘click’ into place.

Attach probe

To release push the silver release button on the side of the probe connector and pull gently.

Release probe 22

Gas-Tec

Operation

Attach the shoulder strap. English

Attach both ends of the strap to the metal rods at either end of the Gas-Tec. Using headphones: Plug the headphones into the headphone jack at the base of the Gas-Tec. This will silence external alarms and notifications of gas detection, leaving only the user to hear the increasing tones.

3.2 Start Up When the hydrogen cylinder and the probe are properly attached, the Gas-Tec can be switched on. 1. Press the ON/OFF button.

The LCD display will run a self test and then be ready for use.

2. Press START.

3. The LCD display will show the message ‘Turn on the gas supply’ (if the cylinder is not already turned on).

4. To open up the gas supply, turn the gas cylinder ON/OFF valve on the end of the hydrogen bottle anticlockwise. Turn until there is no more resistance. The pump will start as soon as the Gas-Tec detects the flow of hydrogen.

N.B.) If the Gas pressure exceeds 1800 psi, a warning message will appear on the display and the gas cylinder valve MUST BE CLOSED IMMEDIATELY.

5. Providing the gas supply is adequate, the pump will start.

23

Operation

Gas-Tec

English

6. If the pump does not start, the 'Gas Supply Low' message will display on the LCD display. Check that the valve of the cylinder has been opened. If not, open it. If it is open, the gas pressure is not adequate. Switch the unit off at the ON/OFF switch and replace the cylinder. 7. After the pump starts, hydrogen will begin to flow into the Gas-Tec. The LCD display will monitor progress as the gas builds up inside the chamber. During this process a countdown timer will be visible. When there is enough gas to begin operation, an audible 'beep' will sound.

8. When prompted, press the igniter, (the red cylindrical button under the Gas-Tec). Press it in until it clicks. This should light the hydrogen, and the beeping will stop. If the beeping continues. Wait for five seconds and then press the igniter again.

The space between each attempt is important and it is normal for the ignition to take up to three attempts.

9. When the gas is lit, the flame icon will stop flashing and the audible tone will end. 10. The screen will ask if the Gas-Tec is ‘In clean air?’

If the unit has just been turned on or it may not be in fresh air, free from hydrocarbons, press ‘No’. The unit will work adequately for most leak location applications, where a relative reading is needed, and this is the fastest way to getting operational.



If the unit has warmed up for 10-15 minutes and you are confident that it is in fresh air free from hydrocarbons press ‘Yes’. This will give maximum accuracy and is the best approach for survey work. Note that the unit does not store any adjustments introduced by this process after turning off.

11. The pump will be heard continuously while the unit is in use.

24

Gas-Tec

Operation

1. Now the Gas-Tec is ready for use. Place the probe towards the suspected leak or to the survey area and view the display for read-out information. Alternatively attach the Gas-Tec to a Trigger survey unit to use it in a moving vehicle. 2. Gas-Tec continuously records data relating the gas reading to a log which is stored in the internal non-volatile memory. (For further details, see section VI.)

The Gas-Tec includes a GPS location monitor. Make sure the antenna is not obstructed and monitor the GPS icon on the LCD display for ‘lock’ information.



Depending on the coverage in the area, it can take from 30 seconds to 8 minutes for the antenna to lock on to a sufficient number of satellites.



At this point, the GPS icon at the top of the LCD display will register a lock (see Sections VI.3 and VI.4 for further information).



Providing the GPS is locked on to satellites, details of the instrument’s location will be written to the log.



If using the Gas-Tec for invehicle surveys, it is recommended that a ‘lock’ is achieved outside of the vehicle before installation to the Trigger survey unit (see Section VIII.2) takes place.

The Gas-Tec in use

3. The Gas-Tec monitors the level of hydrocarbon in the sample. The number on the screen shows the concentration of hydrocarbon gas in parts per million (ppm). If the screen shows a negative value for the gas reading, perform a manual zero. Press the button by the ‘INFO’ string. Choose the ‘ZERO’ option and zero the machine manually.

Press the ‘Info’ button to bring up a choice offering opportunities to change options on the volume of the alarm signal, and the nature of the display. Pressing the 'DISP' button will take you to the screen of the 'Format Menu' shown in section V.1. Choosing the ‘GPS’ option will display GPS data such as longitude, latitude, and number of satellites locked onto. The screen you will reach is illustrated in Section VI.3.



Users have the option of three display formats. All offer ppm numerical readings, with options for moving bar or cityscape, and a screen showing all three. Gas-Tec offers a choice of three ranges 0-100 ppm, 0-1000 ppm and 0-10,000 ppm. The range chosen is indicated just above the graphical output. (See section V for instructions on how to change between these options).



Please note that whilst the Gas Tec V will respond to gas and give a relative reading immediately the displayed reading may not be sufficiently accurate for surveys requiring absolute values until the FID has warmed up and stabilised. This may take approximately 15 minutes depending on environmental conditions. 25

3.3 Detecting gas

Operation English



Gas-Tec

The ‘MARK’ button can be pressed to record a significant event. Pressing by ‘MARK’ will assign a flag into the datalog for retrieval at a later stage. Bars in the display that are clear rather than black indicate ‘MARKed’ readings in real time.

4. An audible click will sound if the Gas-Tec measures a sudden increase of hydrocarbon gas. The rate of clicking will increase in proportion to the level of hydrocarbon detected. Adjust the volume of the click using the ‘VOL’ button. This option can be accessed by pressing the 'INFO' button as shown above.

5. Keep the Gas-Tec upright. The Gas-Tec will not detect gas if the unit is tilted more than 30 degrees from the vertical. If this happens, an alarm will sound and a message will display. Restore the Gas-Tec to an upright position. Gas detection will restart automatically, the beep will stop and the message will clear.

If the Gas-Tec falls sideways, the flame may go out. Check for this by inspecting the flame icon in the middle of the status bar at the top of the LCD display. If the flame icon is flashing, relight the flame by pressing the igniter (see Section III.2).

3.4 Shutting down 1. Press the ‘STOP’ soft key (see ‘Using the soft keys’). 2. At the ‘Do you want to stop readings?’ message, press the ‘YES’ soft key. 3. VERY IMPORTANT: When asked to ‘Turn off gas’ do this by turning the valve on the gas bottle clockwise until tight. 4. VERY IMPORTANT: Wait for ten minutes to allow the gas to dissipate. The pump will continue to run until the gas cylinder pressure drops to 150 psi. 5. Switch off the Gas-Tec by holding down the ‘ON/OFF’ switch for 3 seconds. Count down on LCD display will show closing down. 6. VERY IMPORTANT: Before leaving or recharging the Gas-Tec, CHECK that the gas valve has been closed. It is very important to close the valve completely. If the valve is open, hydrogen leaks into the enclosed space inside the instrument at 20 ml/minute. A build-up of gas could cause an explosion in extreme cases.

What the Gas-Tec shows

English

VI What the Gas-Tec shows 6.1 Overview Gas-Tec makes it easy to pinpoint gas leakages so that they can be dealt with quickly. The data can be checked while recording is taking place, or loaded down later. To find information about the location of the Gas-Tec at a particular time, and other basic aspects of the system, use the ‘Info’ soft key at any time during operation. A choice of screens is provided: ‘System’ and ‘GPS’. A record of the concentration of hydrocarbon gases encountered by the probe as it is carried by the operator is stored in date-stamped files in an internal memory. Data is registered every second and is recorded against the time the record is logged. The built-in GPS, (if locked), allows the position to be logged at the same time. To upload the data, plug the detector's USB connector into a PC (the green led will light on the Gas-Tec when connected). Gas-Tec will be recognised as a memory device, and a folder will open displaying log files in date order. The files can be manipulated or sent via e-mail to interested parties. The data collected by Gas-Tec includes: Column A

6.2 Special events in the record If, during the survey with the detector, an unusual event occurs, and the ‘MARK’ button has been pressed. The flag will be visible in the far right hand column of the report.

6.3 GPS

Details of the status of the GPS can be accessed by pressing the 'INFO' button shown above left, and then GPS. Read the details on the GPS screen above right. If GPS data has been recorded, the data can be converted by web-based applications and then displayed on a map. Gas-Tec thus provides a straightforward way to record and pinpoint gas leaks as well as monitoring survey progress and paths.

Above is shown an example of a route recorded on a Gas-Tec. It was made using Google Earth software. To make a such a map from a .csv file downloaded from a Gas-Tec, Google Earth software must be installed. The software can be downloaded from http://earth.google.co.uk .

6.4 Acquiring and using data from the Gas-Tec To save data to a PC, connect the detector to a USB port. A new window will open showing the log files stored on the internal drive. There will be one file for each session of continuous use. The file name contains the date of the survey. Drop the files to a folder on the PC. Alternatively cut and paste them. Delete the copied files from the internal drive of the Gas-Tec to free up space for future sessions. If the files on the folder occupy all of the available space, the earliest log on the drive will be deleted automatically and the new log file will be created. The files are in .csv format and can be manipulated by standard word-processing applications.

Managing the Gas-Tec

VII Managing the Gas-Tec Earlier sections provided instructions for day-to-day use of the Gas-Tec. In this section we describe the use of functions intended to assist with the long-term management of the detector, setting alerts for servicing, and fine-tuning other parameters of this flexible instrument.

7.1 Admin menu Engineers may wish to set up the Gas-Tec so that they report when a service is due, and possibly cease to work until servicing is undertaken. Bear in mind that this function depends on the date and time set on the service menu (see Section V.2). The Gas-Tec may report that the service has expired due to a failure of the backup battery for the internal clock. These functions should be used with care, and access to them protected by changing the default password. To reach the administration functions of the Gas-Tec switch the unit on and the press the ‘ADMIN’ soft key (the third button down at the right hand side of the LCD display). After entering the Admin menu, the Gas-Tec will not detect gas. To use the Gas-Tec, turn it off using the on/off button and then press again to turn it on. On receipt of a new Gas-Tec the administrator should set a new PIN. (see Section VII.2 below). The menu can also be used to calibrate the Gas-Tec. This function is described in the Service Manual. IMPORTANT NOTE: Accepting the option RESET DEFAULTS on this menu may remove calibration and other settings.

7.2 Set up the detector The screenshots show how to navigate through the menus. The buttons at the right are linked to the labels next to them on the screen. Access a labelled option by pressing the soft key to the right of it. Change the numbers on the screen by using the buttons next to the up and down arrows on the right. To move between the numbers, use the 'NEXT' and 'BACK' soft keys. To do this, enter the default PIN of 1234 and choose the menu option ‘Enter a new Admin PIN’. Ensure a record of the new PIN is kept as this will be needed during set-up and servicing. After entering the correct PIN, a list of options will be displayed 35
