1.1. Correct Use The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors are for use by trained and qualified personnel. They are designed to be used when performing a hazard assessment to: • Assess potential worker exposure to combustible and toxic gases and vapors as well as low level of oxygen. • Determine the appropriate gas and vapor monitoring needed for a workplace. The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors can be equipped to detect up to five gases in the ALTAIR 5 and up to six gases in the ALTAIR 5 IR: • Combustible gases and certain combustible vapors • Oxygen-deficient or oxygen-rich atmospheres • Specific toxic gases for which a sensor is installed. While the instrument can detect up to 25 % oxygen in ambient air, it is approved for use only up to 21 % oxygen. The ALTAIR 5 IR Gas Detector contains one Infrared sensor to detect either CO2 or specific combustible gases up to 100% volume, in addition to up to five other gases. Read and follow all instructions carefully. • Perform a blocked flow test before each day's use if equipped with an integral pump. • Check calibration before each day's use and adjust if necessary. • Check calibration more frequently if exposed to silicone, silicates, lead-containing compounds, hydrogen sulfide, or high contaminant levels. • Recheck calibration if unit is subjected to physical shock. • Use only to detect gases/vapors for which a sensor is installed. • Do not use to detect combustible dusts or mists. " WARNING

• Never block sensors. • Never block pump inlet, except to perform sampling safety test. • Have a trained and qualified person interpret instrument readings. • Do not remove battery pack from instrument while in a hazardous location. • Do not recharge Li Ion battery in a hazardous location. Risk of explosion may occur. • Do not replace alkaline batteries in a hazardous location. • Do not alter or modify instrument. • Use only MSA-approved sampling lines. • Do not use silicone tubing or sampling lines. • Wait sufficient time for the reading; response times vary, based on gas and length of sampling line. • Do not use the instrument with integral pump for prolonged periods in an atmosphere containing a concentration of fuel or solvent vapors that may be greater than 10%LEL. INCORRECT USE CAN CAUSE SERIOUS PERSONAL INJURY OR DEATH. This Class A digital apparatus complies with Canadian ICES-003. For users in Australia/ New Zealand: The charge cradle is a Class A product. In a domestic environment, this product may cause radio interference, in which case, the user may be required to take adequate measures. 1.2. Safety and Precautionary Measures Carefully review the following safety limitations and precautions before placing this instrument in service. Incorrect use can cause serious personal injury or death. The Altair 5 Multigas Detector is designed to: • Detect gases and vapors in air only " WARNING 1-2

(for available sensors,see Section 5.3) • Perform a blocked flow test (see section 4.2) before each day's use if equipped with an integral pump. • MSA recommends to check the instrument's functionality (see section 3.6) and carry out a routine inspection each day before use. • Perform calibration check (see section 3.7) before each day's use to verify proper instrument operation. Adjust calibration if the readings are not within the specified limits. • Check calibration more frequently if unit is subjected to physical shock or high levels of contaminants. Also, check calibration more frequently if the tested atmosphere contains the following materials, which may desensitize the combustible gas sensor and reduce its readings: • Organic silicones • Silicates • Lead-containing compounds • Hydrogen sulfide exposures over 200 ppm or exposures over 50 ppm for one minute. The minimum concentration of a combustible gas in air that can ignite is defined as the Lower Explosive Limit (LEL). A combustible gas reading of "100” or "5.00” indicates the atmosphere is above 100 % LEL or 5.00 %vol CH4, and an explosion hazard exists. Move away from hazardous area immediately. Do not use the ALTAIR 5 or ALTAIR 5 IR Multigas Detectors to test for combustible or toxic gases in the following atmospheres as this may result in erroneous readings: • Oxygen-deficient or oxygen-rich atmospheres • Reducing atmospheres • Furnace stacks • Inert environments (only IR sensors acceptable for use) • Atmospheres containing combustible airborne mists/dusts. Do not use the ALTAIR 5 or ALTAIR 5 IR Multigas Detectors to test for combustible gases in atmospheres containing vapors from liquids with a high flash point (above 38 °C, 100°F) as this may result in erroneously low readings. 1-3

Do not press on the face of the sensors, as this may damage them and cause erroneous readings. Do not use compressed air to clean the sensor holes, as the pressure may damage the sensors. Allow sufficient time for unit to display accurate reading. Response times vary based on the type of sensor being utilized (see Section 5.3, "Sensor Performance Specifications"). For units with a sample pump, allow a minimum of 1 second per foot (3 seconds per meter) of sample line to allow the sample to be drawn through the sensors. Sampling lines made from 0.062 inch (1.57 mm) inner diameter tubing provide fast transport times to the instrument; however, they must be limited to 50 feet (15 m) in length. Sampling of reactive toxic gases (Cl2, ClO2, NH3) must only be done with the reactive gas sample line and probe kits listed in the Accessories table in Section 6.2. All instrument readings and information must be interpreted by someone trained and qualified in interpreting instrument readings in relation to the specific environment, industrial practice and exposure limitations. Observe proper battery maintenance Use only battery chargers made available by MSA for use with this instrument; other chargers may damage the battery pack and the instrument. Dispose of in accordance with local health and safety regulations. Be aware of environmental conditions A number of environmental factors may affect the oxygen and toxic sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually present in the atmosphere. After exposure to negative (°C) temperatures, units with HCN (hydrogen cyanide) sensors should be bump checked and calibrated, if necessary, after returning to room temperature. Be aware of the procedures for handling electrostatically sensitive electronics The instrument contains electrostatically sensitive components. Do not open or repair the unit without using appropriate electrostatic discharge (ESD) protection. The warranty does not cover damage caused by electrostatic discharges. 1-4

The instrument should be powered down and the sensor re-seated. 2.6 Monitoring Toxic Gases The instrument can monitor the concentration of toxic gases in ambient air. Which toxic gases are monitored depends on the installed sensors. The instrument displays the gas concentration in parts per million (PPM) or mg/m3 on the Measuring page. If an alarm activates while using the instrument, leave the area immediately. Remaining in the area under such circumstances can cause serious personal injury or death. The instrument has four gas alarms: • HIGH Alarm • LOW Alarm • STEL Alarm • TWA Alarm " WARNING 2-14

STEL or TWA limits, the: • alarm message displays and flashes in combination with the corresponding gas concentration: • backlight turns ON • alarm sounds (if active) • alarm LEDs flash (if active) • vibrating alarm triggers (if active). 2.7 Monitoring Oxygen Concentration The instrument monitors oxygen concentration in ambient air. The alarm setpoints can be set to activate on two different conditions: • Enriched - oxygen concentration > 20.8 % or • Deficient - oxygen concentration < 19.5 %. While the instrument can detect up to 25% oxygen in the ambient air, it is approved for use only up to 21% oxygen-content. If an alarm activates while using the instrument, leave the area immediately. Remaining in the area under such circumstances can cause serious personal injury or death. " WARNING Figure 2-6. Alarm Conditions (High Alarm shown) 2-15

• the alarm message displays and flashes in combination with the oxygen gas concentration • backlight turns ON • alarm sounds (if active) • alarm LEDs flash (if active) • vibrating alarm triggers (if active). The LOW alarm (oxygen deficient) is latching and will not reset even when the O2 concentration rises above the LOW setpoint. To reset the alarm, press the ▲ button. If the alarm is latching, the ▲ button silences the alarm for five seconds. Alarms can be made latching or unlatching via MSA Link False oxygen alarms can occur due to changes in barometric pressure (altitude), humidity, or extreme changes in ambient temperature. It is recommended that an oxygen calibration be performed at the temperature and pressure of use. Be sure that the instrument is in known fresh air before performing a calibration. 2.8. Monitoring Combustible Gases The instrument can be equipped with a catalytic combustible sensor that detects a variety of combustible gases up to 100% LEL and displays the reading as either %LEL or %VOL. The Altair 5IR can contain both a catalytic combustible sensor and an IR combustible sensor, if equipped. The IR sensor can display the reading in either %LEL or %VOL, depending on the sensor chosen. If an alarm activates while using the instrument, leave the area immediately. Remaining in the area under such circumstances can cause serious personal injury or death. The instrument has two alarm setpoints: • HIGH Alarm • LOW Alarm " WARNING 2-16

the instrument: • alarm message displays and flashes in combination with the corresponding gas concentration: • backlight turns ON • alarm sounds (if active) • alarm LEDs flash (if active) • vibrating alarm triggers (if active). When gas reading exceeds 100% of the Lower Explosive Limit (LEL), the instrument enters a LockalarmTM state and displays “XXX” in place of the actual reading. A combustible gas reading of "XXX” indicates the atmosphere may be above 100 % COMB or 5.00 %vol CH4 and an explosion hazard exists. Leave the contaminated area immediately. Certain IR sensors use a calibration gas >100% LEL. When the calibration sequence shown in section 3.8.2 is followed, the combustible LEL sensor will display the "XXX" reading. This state can only be reset by turning the instrument OFF and then ON again. " WARNING 2-17

three Function buttons (see Section 2.2.1). 3.1. Environmental Factors A number of environmental factors may affect the gas sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually present in the atmosphere. Pressure Changes If pressure changes rapidly (e.g., stepping through airlock) the oxygen sensor reading may temporarily shift, and possibly cause the detector to go into alarm. While the percentage of oxygen may remain at or near 20.8 vol%, the total amount of oxygen present in the atmosphere available for respiration may become a hazard if the overall pressure is reduced by a significant degree. Humidity Changes If humidity changes by any significant degree (e.g., going from a dry, air conditioned environment to outdoor, moisture laden air), oxygen readings can be reduced by up to 0.5 %, due to water vapor in the air displacing oxygen. The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings. This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours. Temperature Changes The sensors are temperature compensated. However, if temperature shifts dramatically, the sensor's reading may shift temporarily. 3-1

Instrument operation is dialog driven from the display with the aid of the three Function buttons (see Section 2.2.1). For more information, see the flow charts in Section 7. Turn the instrument ON with the button. • The instrument performs a self test: During the self test, the instrument checks alarm LEDs, audible alarm, vibrating alarm, and for missing sensors. In case of a missing sensor, the instrument displays the Sensor Missing screen (see section 2.5) and alarms until it is turned OFF. Otherwise, the turn-ON sequence continues. • The instrument displays: • Startup logo • Software version, instrument name and serial number, company name, department, and user names • Sampling safety test (if equipped with an integral pump) • Combustible gas type and sensor units (monochrome display only) • Low Alarm setpoints • High Alarm setpoints • STEL Alarm setpoints (if enabled) • TWA Alarm setpoints (if enabled) • Settings for calibration cylinder • Current date • Last calibration date (if enabled) • CAL due date. If the calibration due date is enabled, the message "CAL DUE; X DAYS" appears on the instrument display. • X = the number of days until a calibration is due, user selectable for 1 to 180 days. If the number of days until calibration is due reaches 0, an alert occurs and "CAL DUE NOW" displays. • Press the ▲ button to clear the alert. 3-2

• Fresh Air Setup option (if enabled). Refer to flowchart in Appendix, Section 7.1 3.2.1 Sampling Safety Test This test is only on units with software version 1.3 or higher for instruments that are equipped with an integral pump. At startup, an alarm (visual, audible, and vibrating) is triggered and the customer is prompted to block the pumps/sampling system of the instrument within 30 seconds. When the instrument detects a pump flow block, it displays a PASS message. The startup sequence resumes. If the instrument does not detect a pump flow block, it displays an error message.The instrument shuts OFF after the customer acknowledges this message by pressing the ▲ button. If this occurs check your sampling system and contact MSA as needed. Users can check the operation of the sampling system anytime during operation by blocking the sampling system to generate a pump alarm. Do not use the pump, sample line, or probe unless the pump alarm activates when the flow is blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which could cause inaccurate readings. Failure to follow the above can result in serious personal injury or death. Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the instrument, readings will be inaccurate and instrument could be damaged. We recommend the use of an MSA sample probe containing a special membrane filter, permeable to gas but impermeable to water, to prevent such an occurrence. " WARNING 3-3

The Fresh Air Setup (FAS) is for ZERO calibration of the instrument. The FAS has limits. If a hazardous level of gas is present, the instrument ignores the FAS command and the instrument alarm activates. NOTE: The Fresh Air Setup does not apply to the CO2 sensor. Do not activate the Fresh Air Setup unless you are certain you are in fresh, uncontaminated air; otherwise, inaccurate readings can occur, which can falsely indicate that a hazardous atmosphere is safe. If you have any doubts as to the quality of the surrounding air, do not use the Fresh Air Setup feature. Do not use the Fresh Air Setup as a substitute for daily calibration checks. The calibration check is required to verify span accuracy. Failure to follow this warning can result in serious personal injury or death.

Turn ON the ALTAIR 5 or ALTAIR 5 IR Multigas Detector in clean, fresh air. 2. Verify that readings indicate no gas is present. 3. Attach regulator (supplied with calibration kit) to the cylinder. 4. Connect tubing (supplied with calibration kit) to the regulator. 5. Attach other end of tubing to the instrument. 6. Open the valve on the regulator, if so supplied. • The reading of the ALTAIR 5 or ALTAIR 5 IR Multigas Detector display should be within the limits stated on the calibration cylinder or limits determined by your company. • If necessary, change cylinder to introduce other calibration. • If readings are not within these limits, the ALTAIR 5 Multigas Detector requires recalibration (see Section 3.8). If using the MSA GALAXY Test Stand for the Calibration (bump) check, a check-mark appears on the ALTAIR 5 display for 24 hours following a successful bump of all operational sensors. 3.8. Calibration Span Calibration gases and Span Calibration values are shown in Section 5.4, along with the appropriate MSA calibration gas cylinder. CSA requires (per 22.2 NO. 152) that the instrument's sensitivity be tested before each day's use on a known concentration of methane equivalent to 25 to 50% of full scale concentration. Accuracy must be within 0 to +20% of actual. Correct accuracy by performing the calibration procedure given in this manual. 3-15

procedure or automatically by using the GALAXYTM test stand. Refer to Section 3.8.5 for additional GALAXY information. NOTE: The GALAXY is not a CSA certified method of calibration. Calibration must be performed by using a flow regulator with a flow rate set to 0.25 liters per minute for a diffusion instrument. For instruments with an integral pump, use of the demand regulators listed in Section 6.2 is recommended. Attention! Special conditions with toxic gases! Reactive toxic gases (chlorine, ammonia, chlorine dioxide) have the property of diffusing into the rubber and plastic tubes so that the volume of test gas available in the instrument would no longer be sufficient to correctly perform instrument calibration. For this reason, when calibrating the instrument with reactive toxic gases, certain prerequisites are required; otherwise, incorrect calibration could result: • A special pressure regulator • The shortest possible connection tubes between the pressure regulator and the instrument. • Connection tubes made from a material that does not absorb the test gases (e.g., PTFE). NOTE: If using normal tubes and pressure regulators, expose them to the required test gas for an extended time period. Keep these materials dedicated for use with that test gas only; do not use them for other gases. For example: for chlorine, allow the entire contents of a test gas cylinder to flow through the pressure regulator and tubes before using to calibrate the instrument. Mark these materials for use with chlorine only. The phosphine (PH3) sensor used in the instrument is highly cross-sensitive to hydrogen sulfide (H2S) gas. Do not use calibration gas that contains H2S on an instrument that is configured with a PH3 sensor. " WARNING 3-16

Replacement of an IR sensor should only be done at an authorized MSA Service Center. Before handling the PC board, the user must be properly grounded; otherwise, static charges could damage the electronics. Such damage is not covered by the warranty. Grounding straps and kits are available from electronics suppliers. Remove and reinstall sensors carefully, ensuring that the components are not damaged; otherwise instrument intrinsic safety may be adversely affected, wrong readings could occur, and persons relying on this product for their safety could sustain serious personal injury or death. To add an LEL, O2, CO or H2S sensor to an instrument that is not already equipped with a full array of sensors, remove the sensor plug from in front of the formerly unused sensor housing. While instrument case is open, do not touch any internal components with metallic/conductive objects or tools. Damage to the instrument can occur. " CAUTION " WARNING " CAUTION 4-5

2. Remove the battery pack. 3. Remove the two remaining case screws, and remove the case front. 4. Gently remove the sensor to be replaced. • Using fingers only, gently remove the tox, combustible or oxygen sensor. 5. Carefully align the new sensor contact pins with the sockets on the printed circuit board. 6. Press the new sensor into place. • Ensure groove in combustible sensor is aligned with notch in sensor slot. • If a sensor is not to be installed, ensure that a sensor plug is installed properly in its place. 7. If replacing sensor filter at this time: • Carefully peel off old filter, taking care not to damage the inside of the case. • On new filter, peel off backing exposing adhesive. Note proper orientation of filter and apply to inside of front case, adhesive side against case. • Press filter into place, taking care not to damage filter surface. 8. Re-install the sensor gasket in the case front. • Ensure sensor gasket is properly installed. 9. Re-install the screws. 10. Go into the sensor setup and turn ON the sensor. Figure 4-3.

least 30 minutes before calibration. Calibrate instrument before use. Calibration is required after a sensor is installed; otherwise, the instrument will not perform as expected and persons relying on this product for their safety could sustain serious personal injury or death. 4.5. Replacing the Filter (for instruments with integral pump) 1. Turn OFF the instrument. 2. Unscrew the two captive screws from the clear filter cover on the back of the instrument to access the filter. 3. Carefully lift out the O-ring and the filter disk. 4. Place the new filter disk in the recess. 5. Replace the O-ring in the recess. 6. If the instrument is used in dusty environments, the fibrous dust filters supplied in Maintenance Kit P/N 10094829 should be used in addition to the filter disk. Place the fibrous dust filter in the clear filter cover. If the instrument is configured for a reactive toxic gas (Cl2, ClO2, NH3), use only the filters supplied in the Reactive Gas Maintenance Kit P/N 10099533. 7. Re-install the clear filter cover on the back of the instrument. 4.6. Cleaning the Instrument Clean the exterior of the instrument regularly using only a damp cloth. Do not use cleaning agents.

1.1. Utilisation conforme Les détecteurs multigaz ALTAIR 5 et ALTAIR 5 IR doivent être utilisés par du personnel formé et qualifié. Il sont conçus pour être utilisés dans le cadre d'une évaluation de risques pour : • Évaluer l'exposition potentielle des ouvriers aux gaz et vapeurs inflammables et toxiques ainsi qu'à un faible niveau d'oxygène. • Déterminer la surveillance appropriée des gaz et vapeurs nécessaire sur un lieu de travail. Les détecteurs multigaz ALTAIR 5 et ALTAIR 5 IR peuvent être configurés pour détecter un maximum de cinq gaz pour l'ALTAIR 5 et un maximum de six gaz pour l'ALTAIR 5 IR : • Les gaz inflammables et certaines vapeurs inflammables • Atmosphères pauvres en oxygène ou riches en oxygène • Les gaz toxiques spécifiques pour lesquels un capteur est installé. Bien que l'appareil puisse détecter jusqu'à 25 % d'oxygène dans l'air ambiant, il n’est homologué pour être utilisé que dans des atmosphères ne contenant pas plus de 21 % d'oxygène. Le détecteur de gaz ALTAIR 5 IR contient un capteur infrarouge pour détecter le CO2 ou des gaz combustibles spécifiques jusqu'à une concentration de 100 % en volume, en plus de jusqu'à cinq autres gaz. Lire et observer attentivement toutes les instructions. • Effectuer un test d'écoulement bloqué avant chaque utilisation quotidienne si l'appareil est équipé d'une pompe intégrale. • Contrôler le calibrage avant chaque utilisation quotidienne et l'ajuster si nécessaire. • Contrôler le calibrage plus fréquemment en cas d'exposition au silicone, aux silicates, aux composés à base de plomb, à l'hydrogène sulfuré ou à des niveaux élevés de contaminants. • Contrôler de nouveau le calibrage si l'unité est soumise à des chocs physiques. AVERTISSEMENT !

lesquels un capteur est installé. • Ne pas utiliser pour détecter des poussières ou brumes inflammables. • S'assurer qu'une quantité suffisante d'oxygène est présente. • Ne pas obturer des capteurs. • Ne jamais obturer l'entrée de la pompe, sauf pour réaliser un test de sécurité d'échantillonage. • Confier l'interprétation des valeurs affichées sur l'appareil à une personne formée et qualifiée. • Ne pas retirer le bloc de piles de l'appareil dans une zone dangereuse. • Ne pas recharger la pile lithium-ion dans une zone dangereuse. Risque d'explosion. • Ne pas remplacer les piles alcalines dans une zone dangereuse. • Ne pas modifier l'appareil. • Utiliser uniquement des lignes d'échantillonnage homologuées par MSA. • Ne pas utiliser des tuyaux ou des lignes d'échantillonnage en silicone. • Attendre suffisamment longtemps avant de lire les valeurs ; les temps de réponse varient selon le gaz et la longueur de la ligne d'échantillonnage. • Ne pas utiliser l'appareil avec la pompe intégrale pendant une durée prolongée dans une atmosphère contenant une concentration de vapeurs de carburant ou de solvant pouvant dépasser 10 % de la LIE (limite inférieure d'explosivité. TOUTE UTILISATION NON CONFORME PEUT OCCASIONNER DES BLESSURES GRAVES VOIRE MORTELLES. Cet appareil numérique de classe A satisfait à la norme canadienne ICES-003. Pour les utilisateurs d'Australie/Nouvelle-Zélande : le berceau de charge est un produit de classe A. Dans un environnement résidentiel, ce produit peut causer des interférences radio, et dans ce cas l'utilisateur peut devoir prendre des mesures adéquates. 1-2

adopter Observer attentivement les limitations et précautions de sécurité suivantes avant de mettre cet appareil en service. Toute utilisation non conforme peut occasionner des blessures graves voire mortelles. Les détecteurs multigaz ALTAIR 5 et ALTAIR 5 IR sont conçus pour : • Détecter les gaz et vapeurs présents dans l'air uniquement. • Détecter seulement les gaz toxiques spécifiques pour lesquels un capteur est installé (capteurs disponibles voir le Chapitre 6). • Effectuer un test d'écoulement bloqué (voir chapitre 4.2) avant chaque utilisation quotidienne si l'appareil est équipé d'une pompe intégrale. • MSA recommande de contrôler le fonctionnement (voir chapitre 3.6) et d'effectuer une révision de routine chaque jour avant l'utilisation. • Réaliser le contrôle de calibrage (voir chap. 3.7) avant chaque utilisation quotidienne afin de vérifier le fonctionnement correct de l'appareil. Ajuster le calibrage si les valeurs affichées ne sont pas comprises dans les limites spécifiées. • Contrôler le calibrage plus fréquemment si l'unité est soumise à des chocs physiques ou à des niveaux élevés de contaminants. Contrôler également le calibrage plus fréquemment si l'atmosphère testée contient les matières suivantes, qui peuvent désensibiliser le capteur de gaz inflammables et réduire les valeurs qu'il détecte : • Silicones organiques • Silicates • Composés à base de plomb • Expositions à l'hydrogène sulfuré de plus de 200 ppm (partie par million) ou expositions de plus de 50 ppm pour une minute. La concentration minimale d'un gaz inflammable dans l'air qui peut s'enflammer est définie comme la Limite inférieure d'explosivité (LIE). Une valeur de gaz inflammable affichée de « 100 » ou « 5,00 » indique que l'atmosphère est au-dessus 100 % de la LIE ou 5,00 % vol. CH4, et qu'un risque d'explosion existe. S'éloigner immédiatement de la zone dangereuse. Ne pas utiliser le détecteur multigaz ALTAIR 5 ou ALTAIR 5 IR pour 1-3 AVERTISSEMENT !

suivantes car cela peut entraîner des affichages erronés : • Atmosphères pauvres en oxygène ou riches en oxygène • Atmosphères réductrices • Cheminées de fourneaux • Environnements inertes (seuls les capteurs IR peuvent être utilisés) • Atmosphères contenant des brouillards/poussières aérogènes inflammables. Ne pas utiliser les détecteurs multigaz ALTAIR 5 et ALTAIR 5 IR pour tester la présence de gaz inflammables dans des atmosphères contenant des vapeurs issues de liquides avec une température d'éclair élevée (au-dessus de 38 °C, 100 °F), car cela peut entraîner des détections faussement basses. Ne pas obstruer les ouvertures des capteurs, car cela peut occasionner des détections imprécises. Ne pas appuyer sur la face des capteurs, car cela peut les endommager et occasionner des détections erronées. Ne pas utiliser de l'air comprimé pour nettoyer les trous des capteurs, car la pression risque d'endommager les capteurs. Laisser suffisamment de temps à l'unité pour afficher des valeurs précises. Les temps de réaction varient selon le type de capteur utilisé (voir chapitre 5.3, « Spécifications de performance des capteurs »). Pour les unités avec une pompe d'échantillonnage, attendre au moins 3 secondes/mètre de ligne d'échantillonage (1 seconde/pied) pour permettre à l'échantillon d'être amené sur les capteurs. Les lignes d'échantillonnage composées de tuyaux à partir de 0,062 pouce (1,57 mm) de diamètre intérieur permettent des temps de transport rapides vers l'appareil ; toutefois, elles doivent être limitées à 50 pieds (15 m) en longueur. L'échantillonnage des gaz toxiques réactifs (Cl2, ClO2, NH3) doit être effectué seulement avec les kits de ligne d'échantillonnage de gaz réactif et de sonde listés dans le tableau Accessoires de la section 6.2. Toutes les valeurs et informations affichées par l'appareil doivent être interprétées par une personne formée et qualifiée pour l'interprétation des valeurs affichées par rapport à l'environnement spécifique, à la pratique industrielle et aux limitations d'expositions. Observer la procédure de maintenance appropriée de la pile Utiliser exclusivement des chargeurs de piles mis à disposition par la société MSA pour être utilisés avec cet appareil ; l'utilisation d'autres chargeurs risque d'endommager le bloc de piles et l'unité. Éliminer les piles conformément aux réglementations locales en matière de santé et de 1-4

Un certain nombre de facteurs environnementaux peuvent affecter les lectures des capteurs d'oxygène et de gaz toxiques, y compris les changements de pression, d'humidité et de température. Les changements de pression et d'humidité affectent la quantitéd'oxygène réellement présente dans l'atmosphère. Après l'exposition aux températures (°C) négatives, le fonctionnement des unités équipées de capteurs HCN (acide cyanhydrique) doit être testé et, si nécessaire, les unités doivent être calibrées après avoir été ramenées à la température ambiante.
