MSA ALTAIR Pro Manual De Operación página 8

• Do not use pressurized air to clean the sensor or
alarm holes.
• 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.
• ALTAIR Pro Detector's gas sensors may have a cross-
sensitivity response to common interference gases
other than the gas it is designed to detect. In some
cases, this cross-sensitivity may be positive,
producing a reading higher than actual. In other cases,
it may be negative, giving lower readings or even
negative. Contact MSA for further details if cross-
sensitivity may be an issue.
• Special requirements for ALTAIR PRO O 2 -R Remote
Oxygen Detector:
• Operate this instrument only in ambient
temperatures ranging from 0ºC to 40ºC
(32ºF to 104ºF).
• If the instrument is taken into an environment
where the ambient temperature is 15ºC (59ºF) or
more, higher or lower, than its previous location,
do not use the instrument for a period of
40 minutes to allow the sensor to adjust to the
new conditions. After this 40-minute period,
perform a Fresh Air Set-up (FAS) to re-zero the
sensor. Perform the FAS in fresh air only.
• Quick changes in barometric pressure result in
an offset in the sensor reading for a few
minutes. If this occurs, do not use the
instrument for a period of five minutes; then,
perform a Fresh Air Set-up (FAS) to re-zero the
sensor. Perform the FAS in fresh air only.
• Conditions for Safe Use:
• When it is necessary to replace the battery, use
only a Lithium battery listed in TABLE 6-2.
• Use only the specified MSA cable connecting the
remote Oxygen sensor.
• The maximum length of the remote sensor
connecting cable must not exceed 3.3 meters
(10 feet).
INCORRECT USE OR FAILURE TO FOLLOW THIS WARNING
