MSA ALTAIR 5X Manual De Uso página 7

• 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 XXX indicates the atmosphere is above 100 % LEL, and an explosion hazard exists.
Move away from hazardous area immediately.
• Do not use the device 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 5X and ALTAIR 5X 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.
• Allow sufficient time for device to display accurate reading. Response times vary based on the type of sensor being
utilized (→6.2 Performance
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 device;
however, they must be limited to 50 feet (15 m) in length.
• Sampling of reactive toxic gases (Cl
listed in 8 Ordering
• All device readings and information must be interpreted by someone trained and qualified in interpreting device
readings in relation to the specific environment, industrial practice and exposure limitations.
• Outside the US: The device is suitable and certified for the measurement of the oxygen concentration in gas mixtures
for inertisation according to EN 50104 without alarm function.
Observe Proper Battery Maintenance
Use only battery chargers made available by MSA for use with this device; other chargers may damage the battery pack
and the device. Dispose of in accordance with local health and safety regulations.
Be Aware of Environmental Conditions
A number of environmental factors may affect the sensor readings, including changes in pressure, humidity and
temperature. Pressure and humidity changes also affect the amount of oxygen actually present in the atmosphere.
Be Aware of the Procedures for Handling Electrostatically Sensitive Electronics
The device contains electrostatically sensitive components. Do not open or repair the device without using appropriate
electrostatic discharge (ESD) protection. The warranty does not cover damage caused by electrostatic discharges.
NOTICE
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment
is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
To comply with FCC RF exposure requirements MSA ensures that an approved antenna is installed per FCC ID: 7V1316.
