The ALTAIR Pro Single Gas Detector is:

• For use by trained, qualified personnel

• Designed to be used when performing a hazard assessment to determine the appropriate gas monitoring needed for a workplace.

• To be used when performing a hazard assessment to:

• Assess potential worker exposure to Specific toxic gases for which a sensor is installed

• Oxygen-deficient or oxygen-rich atmospheres for oxygen versions only

NOTE: Although the ALTAIR Pro O2unit will detect up to 25%

oxygen, all ALTAIR Pro versions are not certified or classified for use in atmospheres containing more than 21.0% oxygen.

• Read and follow all instructions carefully.

• Do not use this detector to sample the instrument’s specified gas in gases other than air.

• Perform an alarm function check and a bump test before each day’s use. If the instrument fails either check, the instrument must be taken out of service.

• Recheck response and alarm function if the instrument is subjected to physical shock.

• Do not alter this instrument or make repairs beyond those specified in this manual. Only MSA-authorized personnel may repair this unit; otherwise, damage may result.

• This unit contains a lithium battery; dispose of according to local regulations.

• Wait for an accurate reading; response times vary, based on the gas being detected.

• Use only to detect a gas for which a sensor is installed.

• Do not block sensor.

• Leave area immediately if a gas alarm condition is reached.

WARNING

1-2

• 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 crosssensitivity 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 crosssensitivity may be an issue.

• Special requirements for ALTAIR PRO O2-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).

Data Logging

Session Log

• The ALTAIR Pro Single Gas instrument has the capability of recording 50 of the most recent events.

To transfer data to a pc, hold the TEST button for one second.

• The instrument pages begin to display.

• Put the instrument in IR mode (see FIGURE 2-5).

• Events will be transferred to the PC during this sequence, if:

• the top of the instrument is pointed toward the optional IR Receiving device

• a PC is running MSA FiveStar Link Software (P/N 710946)

• "CONNECT" is pressed in the PC FiveStar LINK Software package.

• The following events are recorded:

• Alarm - Alarm Type - Alarm Value - Time/Date

• Alarm Clear - Alarm Type - Alarm Value - Time/Date

• Cal (Pass/Fail) - Time/Date

• Bump (Pass/Fail) - Time/Date

• Error - Error Type (See Error List) - Time/Date

Periodic Log

• Peak gas readings are periodically logged, based on user settings via the PC. (Default is one sample every three minutes.)

• See TABLE 6-3 for typical performance.

NOTES:

• The time and date is based on the PC time and date. Ensure the PC is correct before communicating with the instrument.

• Changing the instrument battery can result in lost time in the Data log.

• After changing batteries, verify the Time and Date with your PC.

Chapter 3, ALTAIR Pro Function Checks

Confidence and Heartbeat Indicator

• The alarm lights and heartbeat indicator on the display will flash approximately every 60 seconds to indicate that the ALTAIR Pro Detector is operating.

Alarm Test

• Check before each day’s use.

• Turn ON instrument. A one-second test of the alarms will occur; this includes the:

• display

• alarm lights

• vibrator

• horn.

• If these items do not activate, remove the instrument from service.

NOTE: For the Steel Mill version only, the alarm test occurs every

time the button is pressed for one second.

Bump Test

• Check before each day’s use.

• Hold the TEST button for two seconds:

• oxygen versions will display the current oxygen reading; calibrate the unit if it reads other than 20.8%.

• "TEST" "GAS" "?" will display.

• Press the TEST button while "TEST" "GAS" "?" displays to activate the Bump Test mode.

• the hourglass and "GAS" will display.

• Apply gas only AFTER the hourglass and "GAS" are displayed.

• If gas is detected, the display will indicate "OK". NOTE: See TABLE 3-1 for applied gases.

• Wait approximately five seconds:

• The "√" that appears on the display:

• indicates that the instrument passed the bump test.

• remains for 24 hours, indicating that a bump test was performed on this instrument within the last 24 hours.

3-1

NOTE: See FIGURE 3-1 for details

• If If the "√" does not appear and and "ERR" is indicated:

• Check that the:

• sensor inlet is not clogged

• correct calibration cylinder is used to perform the bump test

• gas cylinder has not expired and is not empty

• gas was applied at the appropriate time

• gas tubing is seated in the front instrument case during testing.

• Repeat the bump test process as needed.

• If the "√" does not appear,calibrate the instrument and repeat the

Bump Test.

Chapter 4, Calibrating the ALTAIR Pro Single Gas Detector

Regulators and tubing used for bump testing and calibrating Cl2, ClO2, NH3, HCN or PH3should be labeled by the user for that specific gas and must only be used for that gas exclusively in the future.

• The ALTAIR Pro Single Gas detector must be calibrated if it does not pass a Bump Test or if calibration is required by local procedures. In addition:

• For oxygen instruments, perform a calibration if:

• there are changes in barometric pressure (altitude changes)

• there are extreme changes in ambient temperature and humidity (see TABLE 6-2, "Instrument Specifications").

• the instrument does not pass a bump test.

• Calibration is required at certain intervals by local procedures.

• Special requirements for ALTAIR PRO O2-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 Setup (FAS) to re-zero the sensor. Perform the FAS in fresh air only.
