GasAlertMicro 5 IR
Quick Reference Guide
2
⇒
It is recommended that the combustible sensor be
checked with a known concentration of calibration
gas after any known exposure to contaminants or
poisons (sulfur compounds, silicon vapors,
halogenated compounds, etc.).
⇒
BW recommends to “bump test” the sensors
before each day’s use to confirm their ability to
respond to gas by exposing the detector to a gas
concentration that exceeds the alarm setpoints.
Manually verify that the audible and visual alarms
are activated. Calibrate if the readings are not
within the specified limits.
⇒
Only the combustible gas detection portion of this
instrument has been assessed for performance by
CSA International.
⇒
The combustible sensor is factory calibrated to
50% LEL methane. If monitoring a different
combustible gas in the % LEL range, calibrate the
sensor using the appropriate gas.
⇒
Caution: High off-scale readings may indicate an
explosive concentration.
⇒
Protect the combustible sensor from exposure to
lead compounds, silicones, and chlorinated
hydrocarbons. Although certain organic vapors
(such as leaded gasoline and halogenated
hydrocarbons) may temporarily inhibit sensor
performance, in most cases the sensor will
recover after calibration.
⇒
For use only in potentially explosive atmospheres
where oxygen concentrations do not exceed
20.9% (v/v).
⇒
Any rapid up-scaling reading followed by a
declining or erratic reading may indicate a gas
concentration beyond upper scale limit, which can
be hazardous.
⇒
Extended exposure of the GasAlertMicro 5 IR to
certain concentrations of combustible gases and
air may stress the detector element that can
seriously affect its performance. If an alarm
occurs due to a high concentration of combustible
gases, recalibration should be performed, or if
needed, the sensor replaced.
⇒
The BW pump module (M5-PUMP) is certified for
use with the GasAlertMicro 5, GasAlertMicro 5
PID, and GasAlertMicro 5 IR models only.
⇒
When calibrating O
3
and ClO
2
sensors that are
located in the Toxic 2 position of the detector, a
single gas calibration cap must be used to ensure
accurate calibration.
⇒
Use only the GasAlertMicro 5 IR battery pack with
the GasAlertMicro 5 IR detector. The IR battery pack
is not compatible with other GasAlertMicro 5/PID
products and vice versa.
⇒
Replace the CO
2
sensor only in a safe area that is
free of hazardous gas.
