Incorrect use can cause death or serious personal injury.
-
Check function (see section 3.6) each day before use. MSA recommends carrying out a routine
inspection prior to each day's use.
Perform a calibration check (see section 3.7) before each day's use to verify proper device operation. The device must pass the calibration check. If it fails the test, perform a calibration (see
section 3.8) before using the device.
The ALTAIR 5X Multigas Detectors are designed to detect gases and vapors in air only.
Perform a calibration check more frequently if the device is subjected to physical shock or high
levels of contaminants. Also, perform a calibration check more frequently if the tested atmosphere
contains the following materials, which may desensitize the combustible gas sensor and reduce
its readings:
-
-
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 or 5.00 % Vol CH4 and an explosion hazard exists. Move away from hazardous area
immediately.
Do not use the ALTAIR 5X and ALTAIR 5X IR Multigas Detectors to test for combustible or toxic
gases in the following atmospheres as this may result in erroneous readings:
-
Organic silicones
Silicates
Lead-containing compounds
Sulfur compound exposures over 200 ppm or exposures over 50 ppm for one minute.
Oxygen-deficient or oxygen-rich atmospheres
Reducing atmospheres
Furnace stacks
Inert environments (only IR sensors acceptable for use).
US
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 (see section 5.2). 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 device; 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 section 6.2.
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.

The LOW alarm (oxygen deficient) is latching and will not automatically reset even when the O2
concentration rises above the LOW set point. 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 software.
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 device is in known fresh air before performing a calibration.
2.8
Monitoring Combustible Gases
The device 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 % CH4. The ALTAIR 5X IR can
also contain an IR combustible sensor. The IR sensor displays the reading in % Vol.
WARNING
If an alarm is triggered while using the device, leave the area immediately.
Remaining in the area under such circumstances can cause serious personal injury or death.
The catalytic combustible sensor has two alarm setpoints:
HIGH Alarm
LOW Alarm
If the gas concentration reaches or exceeds the alarm setpoint, the device:
- alarm message displays and flashes in combination with the corresponding gas concentration:
- backlight turns ON

Gas Exposure of 100 % LEL
When the reading from the catalytic combustible sensor reaches 100 % of the lower explosive limit
(LEL), the device enters a LockAlarm state and displays “XXX” in place of the actual reading.
WARNING
A catalytic combustible gas reading of "XXX” indicates the atmosphere may be above 100 % LEL or
5.00 % Vol CH4 and an explosion hazard exists. Move away from contaminated area immediately.
For ALTAIR 5X IR devices with an enabled 100 % Vol methane IR sensor, the LockAlarm will clear,
and the catalytic combustible again displays combustible concentrations when the gas sample drops
to a lower level.
For devices without an enabled 100 % Vol methane IR sensor, the user can clear the LockAlarm state
only by turning the device OFF, and then ON again in a fresh air environment.
When catalytic combustible gas reading digits appear, the device is available for measuring gases
once again.
NOTE: LockAlarm of the catalytic combustible sensor occurs during Bump Testing and calibration of a
% Vol combustible IR sensor.
After the IR sensor Bump Test, the LockAlarm must be cleared (as described above) before the
catalytic combustible sensor is again able to measure and provide readings.

Operation
Device operation is dialog driven from the display with the aid of the 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 device 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 have built-in temperature compensation. However, if temperature shifts dramatically, the
sensor reading may shift temporarily.

Sampling System Safety Test
US
WARNING
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
device, readings will be inaccurate and device 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.
Upon startup, an alarm (visual, audible and vibrating) is triggered and the customer is prompted to
block the pumps/sampling system of the device within 30 seconds.
When the device detects a pump flow block, it will display a "PASS" message. The startup sequence
will resume.
ALTAIR 5X MSHA
24
Operation
3.2.2
If the device does not detect a pump flow block, it will display an error message.
The device will shut OFF after the customer acknowledges this message by pressing the  button.
Check your sampling system if this occurs 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.
Fresh Air Setup (FAS) at Device Turn-ON
WARNING
Do not perform 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.
The Fresh Air Setup (FAS) is for device ZERO adjustment.
The FAS has limits. If a hazardous level of gas is present, the device ignores the FAS command and
the device alarm activates.
The ability to perform an FAS at device turn-ON can be disabled by using MSA Link software.
NOTE: The Fresh Air Setup does not apply to the CO2 sensor.

- Demand Flow Regulator(s)
- Tubing appropriate for the gases to be tested
- Kits containing tubing and regulators suitable for reactive and non-reactive gases are available
from MSA.
Performing a Calibration Check
The calibration check is simple and should only take about one minute.
Perform this calibration check before each day's use
For ALTAIR 5X IR units with combustible % Vol IR sensors, the following gas level should not be
exceeded when used for daily Calibration Checks:
IR Methane 100% Vol - 20% Methane Cal Check gas
(1)
Turn ON the device in clean, fresh air.
(2)
Verify that readings indicate no gas is present.
(3)
Attach demand regulator (supplied with calibration kit) to the cylinder.
(4)
Connect tubing (supplied with calibration kit) to the regulator.
(5)
Attach calibration tube to the ALTAIR 5X Multigas Detector pump inlet.
 The reading on the device 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 gases.
 If readings are not within these limits, the device requires recalibration. See section 3.8.

Calibration
The ALTAIR 5X instrument can be calibrated either manually by using this procedure or automatically
by using the GALAXY® GX2 Test System. See section 3.9 for additional GALAXY® GX2 information.
The use of the demand regulators listed in section 6.2 is recommended.
If a new sensor has been installed, the battery pack has been depleted or a new battery pack has been
installed, allow sensors to stabilize for 30 minutes before calibration is performed.
WARNING
Special conditions with toxic gases!
If the device is to be checked or calibrate for reactive gases, prerequisites are required; otherwise,
incorrect calibration would result in incorrect device operation.
Reactive toxic gases (e.g., 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 device would no longer
be sufficient to correctly perform device calibration.
When calibrating the device with toxic gases, certain prerequisites are required, otherwise incorrect
calibration could result:
- A special pressure regulator
- Shortest possible connection tubes between the pressure regulator and the device
- 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 device. Mark these materials for use with chlorine
only.

Zero Calibration
(1)
Press the  button for five seconds in NORMAL MEASUREMENT page.
 ZERO screen displays.
To skip the ZERO procedure and move directly to the span calibration procedure, push the  button.
If no button is pushed for 30 seconds, the device prompts user to
perform a SPAN calibration before device returns to the
NORMAL MEASUREMENT page.
To perform ONLY a Fresh Air Setup at this time, press the
q button. The device then performs a Fresh Air Setup as
described in section 3.2.2. When the Fresh Air Setup is complete,
the device returns to the normal Measure screen.
(2)
Press the  button to confirm the ZERO screen, i. e. to
execute zero calibration.
 The message "SENSOR REFRESH" displays,
followed by the message "ZERO CALIBRATION".
 The "REFRESH" message does not appear if a catalytic combustible sensor is not installed.
 ZERO calibration starts.
 A progress bar shows the user how much of the calibration has been completed.
NOTE: During the first moments of a ZERO calibration, the
combustible sensor reading may be replaced by a moving display
of “PLEASE WAIT”. This is normal.
ALTAIR 5X MSHA
US
33
Operation
 After the ZERO calibration is completed, the device
displays either
“ZERO CALIBRATION PASS”
or
“ZERO CALIBRATION FAIL”.
 Only if the device passes the zero calibration, the
SPAN screen displays.
3.8.2
Span Calibration
To skip the Span calibration procedure, push the  button.
NOTE: If the SPAN calibration of the combustible sensor is skipped after a successful ZERO calibration, the combustible sensor reading may be replaced with a moving display of “PLEASE WAIT”
for a few moments. This is normal and the device is fully operational once a combustible gas
reading reappears.
If no button is pushed for 30 seconds, span calibration is skipped.
Because of the different possible combinations of gases that are possible, skipping a Span calibration
could advance the user to the Span calibration of another installed sensor, or back to Measuring mode.
When calibrating with combustible gases > 100 % LEL, select the "Yes" option to prompt "Span Calibration?" BEFORE applying gas to the device.

Press the  button to calibrate (span) the device.
 “SPAN CALIBRATION“ flashes
 SPAN calibration starts.
 A progress bar shows the user how much of the calibration has already been completed.
ALTAIR 5X MSHA
34
Operation
 After the SPAN calibration is completed, the device
displays either
“SPAN CALIBRATION PASS”
or
“SPAN CALIBRATION FAIL”
 The device returns to Measuring mode.
If a sensor is nearing its end-of-life, the "PASS" display is followed by the Sensor Life indicator
 display.
- While the sensor is still fully functional, this warning gives the user time to plan for a replacement
sensor to minimize downtime.
- The  indicator blinks as the device returns to Measure mode.
- After 15 seconds, the blinking stops, but the  indicator continues to display during ongoing operations as a reminder of a sensor’s pending end-of-life.
If a span calibration fails:
- The Sensor Life Indicator  blinks to show a sensor has reached its end-of-life and should be
replaced.
- The device remains in the Sensor Life alarm condition until the  button is pressed.
- After the alarm is cleared, the device enters Measure mode and the Sensor Life indicator  blinks
during ongoing operations until the sensor is replaced and/or successfully calibrated.
Span calibration can fail for reasons other than a sensor at the end of its life. If a span calibration failure
occurs, verify items such as:
- sufficient gas remaining in the calibration cylinder
- gas expiration date
- integrity of calibration tubing/fittings, etc.
NOTE: Reattempt the span calibration before replacing the sensor.
3.8.3
Finishing Successful Calibration
Remove the calibration tube from pump inlet.
- The calibration procedure adjusts the span value for any sensor that passes the calibration test.
Sensors that fail calibration are left unchanged.
- In the ALTAIR 5X IR, a combustible IR sensor calibration causes the catalytic combustible sensor
to enter the LockAlarm condition.
-
-
A device with a % Vol methane IR sensor automatically recovers from LockAlarm. For other
devices, the Lock-Alarm state is cleared by turning the device OFF, then ON while in a fresh
air environment.
See section 2.9 for details.
Since residual gas may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.

Verifying Pump Operation
Users can check operation of the sampling system any time during operation by blocking the sampling
system to generate a pump alarm.
When the pump inlet, sample line or probe is blocked, the pump alarm must activate.
Once gas readings are displayed, plug the free end of the sampling line or probe.
- The pump motor shuts down and an alarm sounds.
- "PUMP ERROR" flashes on the display.

Press the  button to reset the alarm and restart the pump.
If the alarm does not activate:
- Check the sample line and probe for leaks.
- Once leak is fixed, recheck pump alarm by blocking the flow.

Press the  button to reset the alarm and restart the pump.
WARNING
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. If a sample line or probe is installed and the pump alarm does not
activate, remove the line or probe and repeat the test. This will provide information on where the
blockage is located.
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
device, readings will be inaccurate and device 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.
During operation, a pump alarm may occur when the:
Flow system is blocked
Pump is inoperative
Sample lines are attached or removed.
-
To Clear Pump Alarm
(1)
Correct any flow blockage.
(2)
Press the  button.
 The Pump will now restart.
