SAFETY REGULATIONS MSA
1. Safety Regulations
1.1. Correct Use
The ALTAIR PRO is a portable instrument for monitoring toxic gases and oxygen
deficiency or excess in the workplace. It is used exclusively for monitoring and not
for measuring gas concentrations in the ambient air. It must be serviced and
repaired by qualified and authorised personnel.
It is imperative that this operating manual be read and observed when using this
instrument. In particular, the safety instructions, as well as the information for the
use and operation of the apparatus, must be carefully read and observed.
Furthermore, the national regulations applicable in the user's country must be
taken into account for a safe use.
Attention!
This product is supporting life and health. Inappropriate use,
maintenance or servicing may affect the function of the device and
thereby seriously compromise the user’s life.
Before use, the product operability must be verified. The product must
not be used if the function test is unsuccessful, it is damaged, a
competent servicing/maintenance has not been made, genuine MSA
spare parts have not been used.
Alternative use, or use outside this specification, will be considered as noncompliance. This also applies especially to unauthorised alterations to the
apparatus and to commissioning work that has not been carried out by MSA or
authorised persons.
1.2. Liability Information
MSA accepts no liability in cases where the product has been used
inappropriately or not as intended. The selection and use of the product are the
exclusive responsibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect
to the product are voided, if it is not used, serviced or maintained in accordance
with the instructions in this manual.

MSA SAFETY REGULATIONS
1.3. Safety and Precautionary Measures to be Adopted
Attention!
The following safety instructions must be observed implicitly. Only in
this way can the safety and health of the individual operators, and the
correct functioning of the instrument, be guaranteed.
Use instrument only for stipulated gases
The ALTAIR PRO is used for monitoring and detecting gases in the ambient air.
Thereby, it must be used only for gases for which a sensor is installed in the
instrument.
The sensor must not be blocked during use.
Observe oxygen concentration
Although the ALTAIR PRO unit will detect up to 25% oxygen, all ALTAIR PRO
versions are not certified or approfed for use in atmospheres containing more
than 21% oxygen.
Check function and alarm before each use
In case of failed function tests, the instrument must be removed from use.
Conduct additional tests after any significant impact
The instrument function should also be checked after severe mechanical stress
(dropping, impact etc.) and when the instrument or the sensors have been
exposed to silicon, silicates, lead-containing substances, hydrogen sulphide or
contaminated compounds.
Defective vibration alarm possible
At ambient temperatures < 0 °C, the vibration alarm can give a false alarm or can
fail completely. In such conditions, do no rely solely on the vibration alarm.
Observe BG information
In Germany, observe the BG information BGI 836 (5).

The instrument is a portable gas meter for monitoring gases in the ambient air
and in the workplace.
The instrument is available in three models:
for monitoring oxygen
for monitoring hydrogen sulphide and
for monitoring carbon monoxide
The instrument can detect up
to 25% oxygen in the ambient air.
However, all instrument models are calibrated and permitted only up to
21% oxygen-content.

MSA DESCRIPTION
The response levels for the individual gases are set at the factory
and cannot be
changed during operation. After commissioning the instrument, changes are
possible only with the MSA FiveStar® Link™ Software version 4.4 or higher
(available as option; Æ Description of software).
If the ambient air contains higher gas concentrations, the instrument
ignores the Fresh Air Setup and goes directly to measuring mode after
the self-test.

Attention!
If an alarm is triggered while using the instrument as a monitor, leave
the area immediately.
Remaining on site under such circumstances can cause serious
damage to health or can even lead to death.
The battery condition icon continuously displays in the upper right-hand corner of
the display. As the battery is depleted, battery icon segments go blank until only
the outline of the battery icon remains.
Each battery indicator segment represents approximately 1/4 of the total battery
capacity.

MSA DESCRIPTION
Battery Warning
A battery warning indicates that a nominal two days of operation remain before
the instrument's battery is depleted.
The duration of remaining instrument operation during battery warning
depends on ambient temperature (colder temperatures may reduce
battery life) and the number and duration of alarms during battery
warning.
When the ALTAIR PRO goes into battery warning the:
battery outline indicator flashes
audible alarm sounds every 30 seconds
alarm lights flash every 30 seconds
Battery Shut Down
Attention!
If a Battery Shutdown condition occurs, stop using the instrument and
leave the area immediately. The instrument can no longer alert you of
potential hazards since it does not have enough power to operate
properly.
Failure to follow this warning can result in serious personal injury or
death.
When the battery can no longer operate the instrument, the instrument goes into
Battery Shutdown mode:
battery outline indicator flashes
alarm icon turns ON
alarm sounds every 30 seconds
alarm lights flash
no gas reading display
display alternates between "
BAT" and "ERR"
no other instrument pages can be viewed
The instrument remains in this state until it is turned OFF or the battery is
completely depleted. The alarm lights and the audible alarm can be silenced by
pushing the button.
When the instrument battery is running low, remove it from service and
replace the battery.

changes 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 instrument is in
known fresh air before performing a calibration.

TWA value is automatically reset to zero when the instrument is turned ON.
TWA value is calculated over an eight-our exposure.
The following formula is used to calculate the TWA value:
Sum of 1-minute gas readings/480 minutes = PPM TWA value
If the instrument is ON for less than 8 ours (480 minutes), the balance of the
minute ppm values is set to zero.

Checking the Confidence indicator
The alarm LEDs and the Confidence indicator in the display must flash every
60 seconds after starting the instrument. This indicates the instrument is
operating correctly
Alarm Test
The alarm test must be conducted before each use.
It is part of the self-test.
(1) Turn ON the instrument.
A short alarm is triggered. These include:
temporary display indicators;
alarm LEDs flash;
acoustic signal sounds briefly and
vibration alarm is triggered briefly.
For the Steel Mill version only, the alarm test occurs every time the
button is pressed for one second.

3.10. Calibrating the Instrument
The ALTAIR PRO must be calibrated if it does not pass a bump-test.
Under normal circumstances MSA recommends calibration at least
every six months, however, many European countries have their own
guidelines. Please check your local legislation.
For instruments used to monitor oxygen calibration must be carried out in the
following cases:
any change in the air pressure (including height above sea-level change),
any extreme changes in the atmospheric temperature (Æ Section 5.1),
if the bump-test failed,
at certain intervals by local procedures.
For instruments used to monitor toxic gases (CO and H
carried out in the following cases:
after major shocks,
any extreme changes in the atmospheric temperature,
after use under high gas concentrations,
if the bump-test failed,
at certain intervals by local procedures.

, ClO2,
2
Make sure that the calibr
ation is carried out in clean, non-contaminated
ambient air.
Due to high reactivity of Cl2 and ClO2, gas, ambient humidity and
calibration tubing material can react with the gas and cause the
concentration reading to be lower than the actual concentration. It is,
therefore, necessary to use dry tubing when calibrating or bump
checking with these gases. For best calibration, use the shortest
possible tubing to connect to the calibration cylinder for these gases.

Therefore, calibrate the instrument under the conditions of use. The
calibration must be carried out in clean, non-contaminated ambient air.
