suitable calibration gas.
Perform a bump test each day before use
Perform a bump test before each day's use to verify proper operation. The device
must pass the bump test. If it fails the test, perform a calibration before using the
device.
Perform a bump test more frequently if the device is subjected to physical shock or
high levels of contaminants. Also, perform a bump test more frequently if the tested
atmosphere contains the following materials, which may desensitize the combustible gas sensor and reduce its readings:
- Organic silicones
- Silicates
- Lead-containing compounds
- Hydrogen sulphide exposures over 200 ppm or exposures over 50 ppm for
one minute.
Check minimum concentration of a combustible gas
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 CH
ists. Move away from hazardous area immediately.

Page 24
When gas reading exceeds 100% LEL CH4, the device enters a
Lock Alarm state , the combustible sensor shuts down and displays
“xxx” in place of the actual reading. This state can only be reset by turning the device off and on in a fresh air environment.
Attention!
A combustible gas reading of "100” indicates the atmosphere is above
100% LEL CH
and an explosion hazard exists. Move away from con-
4
taminated area immediately.
In such cases, the device LockAlarm feature activates.
Check your national standard values for 100% LEL. Some countries use
5% vol and some use 4.4% vol as 100% LEL CH4.
MSAOperation
3 Operation
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 detector to 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 vapour 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.
24
ALTAIR 4X
GB
Page 25
Temperature Changes
The sensors have built-in temperature compensation. However, if temperature
shifts dramatically, the sensor reading may shift. Zero the device at the work site
temperature for the least effect.

Fresh Air Setup [FAS]
The FAS is for automatic Zero calibration of the device.
The Fresh Air Setup has limits. The zero of any sensor that is outside of these limits
will not be adjusted by the FAS command.
Warning!
Do not activate 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.
If a battery charging cycle is interrupted before it is completed [4 hours
for a fully discharged battery], allow the device’s internal temperature to
stabilize for 30 minutes before performing a Fresh Air Setup.

O2
The device can be calibrated either manually using this procedure or automatically
using the GALAXY Test Stand.
Calibration must be performed using a flow regulator with a flow rate set to
0.25 litres per minute.
If a battery charging cycle is interrupted before it is completed [4 hours for a fully
discharged battery], allow the device’s internal temperature to stabilise for
30 minutes before performing a Calibration.
Under normal circumstances MSA recommends calibration at least
every six months, however, many European countries have their own
guidelines. Please check your national legislation.

If a sensor is nearing its end of life, this "SPAN PASS" indication will be followed by
the end of sensor life warning [♥ symbol]. The ♥ symbol, along with the gas type of
the sensor nearing its end of life, will blink for 15 seconds when the device returns
to measure mode. When in measure mode, the ♥ symbol is continuously displayed.
Finishing Calibration
(1) Close the valve on the regulator.
(2) Remove the calibration cap.
The calibration procedure adjusts the span value for any sensor that passes the ca-
libration test; sensors that fail calibration are left unchanged. Since residual gas
may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.
Autocalibration Failure
If the span calibration is unsuccessful:
- A sensor life indicator is displayed [Alarm symbol and ♥ symbol] to show the
sensor has reached its end of life and should be replaced.
- The device will remain in alarm state until the S button is pressed.
- The Alarm symbol and ♥ symbol will remain on the display until a successful
calibration or sensor in question is replaced.
A span calibration can fail for many reasons besides sensor at the end
of his life. If a span calibration failure occurs, items such as remaining
gas in the calibration cylinder, gas expiration date, security of the calibration cap, etc. should be verified and calibration should be repeated
prior to replacing the sensor.
