1. Instrument Safety and Certifications
ATTENTION:
• Read and follow all instructions carefully.
• Check calibration before each day’s use and adjust if necessary.
• Check calibration more frequently if exposed to silicone, silicates, lead-containing
compounds, hydrogen sulfide, or high contaminant levels.
• Recheck calibration if unit is subjected to physical shock.
• Use only to detect gases/vapours for which a sensor is installed.
• Do not use to detect combustible dusts or mists.
• Make sure adequate oxygen is present.
• Do not block pump sample inlet and sensors.
• Use only Teflon sampling lines for reactive gases such as Cl2, PH3, NH3, HCN and
for semivolatile organic compounds such as gasoline and jet fuels.
• Do not place end of sampling line in liquids.
• Use only MSA-approved sampling lines.
• Do not use silicone tubing or sampling lines.
• Wait for accurate reading; response times vary, based on gas/vapor and length of
sampling line.
• Have a trained and qualified person interpret instrument readings.
• Account for sensor reproducibility.
• Properly identify the VOC gas being measured before using VOC response factors
or setting alarm values (exposures, STEL, TWA).
• Recognize that the VOC Auto-range displays readings in increments of 100 ppb.
• Ensure installed PID bulb corresponds to the PID bulb setting on the instrument
display.
• Do not recharge Lithium Ion battery or change Alkaline batteries in a combustible
atmosphere.
• Do not alter or modify instrument.
The SIRIUS Multigas Detector is for use by trained and qualified personnel. It is
designed to be used when performing a hazard assessment to:
• Assess potential worker exposure to combustible and toxic gases and vapours
• Determine the appropriate gas and vapor monitoring needed for a workplace.
The SIRIUS Multigas Detector can be equipped to detect:
• Combustible gases and certain combustible vapours
• Volatile organic compounds (VOCs)
• Oxygen-deficient or oxygen-rich atmospheres
• Specific toxic gases for which a sensor is installed.

Instrument Safety and Certifications1
1.1 Safety Limitations and Precautions
It is very important to have an understanding of PID basics when changing your
PID settings. Failure to properly identify the VOC gas being measured and/or
failure to select the correct Response Factor alarm values (exposure, STEL, TWA)
that match your desired Response Factor and/or the correct bulb, will result in
erroneous readings.
Carefully review the following safety limitations and precautions before placing this
instrument in service:
The SIRIUS Multigas Detector is designed to:
• Detect gases and vapours in air only
• Detect only specified toxic gases for which a sensor is installed.
Perform the following check before each day’s use to verify proper instrument operation:
• Calibration check (see 3.12 Calibration Check). Adjust calibration if the readings are
not within the specified limits.
Check calibration more frequently if the unit is subjected to physical shock or high levels
of contaminants. Also, check calibration more frequently if the tested atmosphere
contains the following materials, which may desensitize the combustible gas sensor and/
or VOC sensor (PID) and reduce its readings:
• Organic silicones
• Silicates
• Lead-containing compounds
• Hydrogen sulfide exposures over 200 ppm or exposures over 50 ppm for one
minute.
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 “100” (in LEL mode) or “4.4”
(in CH4mode) indicates the atmosphere is at 100% LEL or 4.4% CH4(by volume),
respectively, and an explosion hazard exists. In such cases, the instrument LockAlarm
feature activates. Move away from contaminated area immediately.
Do not use the SIRIUS Multigas Detector to test for combustible or toxic gases in the
following atmospheres as this may result in erroneous readings:
• Oxygen-deficient or oxygen-rich atmospheres
• Reducing atmospheres
• Furnace stacks
• Inert environments
• Atmospheres containing combustible airborne mists/dusts
• Ambient pressures other than one atmosphere.
Do not use the SIRIUS Multigas Detector to test for combustible gases in atmospheres
containing vapours from liquids with a high flash point (above 38 °C, 100 °F) as this may
result in erroneously low readings.

1Instrument Safety and Certifications
Allow sufficient time for unit to display accurate reading. Response times vary based on
the type of sensor being utilized (see 8. Performance Specifications). Additionally,
when using a sampling line, allow a minimum of 3 seconds per meter of sampling line to
allow the sample to be drawn through the sensors.
Keep the probe tip above liquid surfaces; otherwise, liquid may enter the system and
block the sample flow, causing inaccurate readings and/or internal damage.
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.
Replace alkaline cells or recharge Li-Ion battery pack in non-hazardous areas only.
Use only battery chargers listed in this manual; other chargers may damage the battery
pack and the unit. Dispose of batteries in accordance with local health and safety
regulations.
Do not alter this instrument or make any repairs beyond those specified in this manual.
Only MSA-authorized personnel may repair this unit; otherwise, damage may result.
1.2 Date of Instrument Manufacture
The date of manufacture of your SIRIUS Multigas Detector is coded into the instrument
serial number.
• The last three digits represent the month (the letter) and the year (the two-digit
number).
• The letter corresponds to the month starting withA for January, B for February, etc.

Quick Start2
2. Quick Start
It is your responsibility to know how to use the SIRIUS Multigas Detector. When used
properly the SIRIUS Multigas Detector will alert you to presence of VOC, combustible
gases and vapours, atmospheres that are rich or deficient in oxygen. It will also alert you
to presence of carbon monoxide and hydrogen sulphide, if it is equipped with sensors for
those gases. The conditions are displayed clearly and simultaneously on face of the
instrument, See Figure 1 for an explanation of the flags, numbers and button operation
on the SIRIUS Multigas Detector.
