above 100% LEL and an explosion hazard exists. In such
cases, the instrument LockAlarm feature activates. Move away
from contaminated area immediately.
•
Do not use the Orion 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
or dusts.
•
Do not use the Orion Multigas Detector to test for combustible
gases in atmospheres containing vapors from liquids with a
high flash point (above 100
O
F) as this may result in erroneously
low readings.
•
Do not block sensor openings as this may cause inaccurate
readings. Do not press on the face of the sensors, as this may
damage them and cause erroneous readings. Do not use
compressed air to clean the sensor holes, as the pressure may
damage the sensors.
•
Allow sufficient time for unit to display accurate reading.
Response times vary based on the type of sensor being utilized
(see "Performance Specifications" section of manual).
Additionally, when using a sampling pump, allow a minimum of
0.7 seconds per foot of sample line to allow the sample to be
drawn through to 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 NiMH battery-pack in
non-hazardous area 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.
