Observe Proper Battery Maintenance; Be Aware Of Environmental Conditions - MSA ALTAIR 4X Operating Manual

• Do not use the ALTAIR 4X Multigas Detector 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.
• Do not block sensor openings as this may cause inaccurate
readings. 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
5.4, "Performance Specifications").
• 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.
• Use of the Galaxy
approved method for calibrating MSHA-approved ALTAIR 4X
instruments.
• Use only calibration gas that is 2.5% Methane with an accuracy of
+5% when calibrating MSHA-approved ALTAIR 4X instruments.
• The maximum acceptable user-set (password protected) Galaxy
Automated Test System tolerance on Bump Limits must be set to
10% or less when calibrating MSHA-approved ALTAIR 4X
instruments.
• For 30 CFR Part 75 determinations, the maximum acceptable
user-set (password protected) Galaxy Automated Test System
tolerance on Bump Limits must only be set to such that 19.5%
oxygen can be detected with an accuracy of +0.5% when
calibrating MSHA-approved ALTAIR 4X instruments.
Risk of explosion: Do not recharge instrument in hazardous area.

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 unit.
Dispose of in accordance with local health and safety regulations. Use
of the GALAXY Automated Test System is an alternate approved
method for charging ALTAIR 4X instruments

Be aware of environmental conditions

A number of environmental factors may affect the sensor readings,
including changes in pressure, humidity and temperature.
