consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any provision of this warranty is
held invalid or unenforceable by a court of competent jurisdiction, such holding will not affect the validity or enforceability of any other
provision.

GasAlertMicro

Introduction

This quick reference guide provides basic information for the
GasAlertMicro. Refer to the user manual on the accompanying
CD-ROM for complete operating instructions. The
GasAlertMicro gas detector (“the detector”) warns of hazardous
gas at levels above user-selectable alarm setpoints.

The detector is a personal safety device. It is your responsibility
to respond properly to the alarm.

Note

The detector is shipped with English as the displayed
language. The Portuguese, Spanish, German, and
French guides have their screenshots displayed in the
corresponding language.

Safety Information - Read First

Use the detector only as specified in this guide, otherwise
the protection provided by the detector may be impaired.

Read the following Cautions before using the detector.

a Cautions

⇒ Warning: Substitution of components may

impair Intrinsic Safety.

⇒ Caution: For safety reasons, this equipment

must be operated and serviced by qualified
personnel only. Read and understand the user
manual completely before operating or
servicing.

⇒ Calibrate the detector before first-time use and

then on a regular schedule, depending on use
and sensor exposure to poisons and
contaminants. BW recommends at least once
every 180 days* (6 months).

GasAlertMicro

Quick Reference Guide

⇒ 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 high
alarm setpoints. Manually verify that the
audible and visual alarms are activated.
Calibrate if the readings are not within the
specified limits.

⇒ It is recommended that the combustible

sensor be checked with a known
concentration of calibration gas after any
known exposure to catalyst
contaminants/poisons (sulfur compounds,
silicon vapors, halogenated compounds, etc.).

⇒ Only the combustible gas detection portion of

this instrument has been assessed for
performance.

⇒ 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.

⇒ Electromagnetic interference may cause

incorrect operation under certain
circumstances.

2

⇒ 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.

⇒ Any rapid up-scaling reading followed by a

declining or erratic reading may indicate a gas
concentration beyond upper scale limit, which
may be hazardous.

⇒ Do not change or charge batteries in a

hazardous location. Doing so will impair the
Intrinsic Safety of the unit and may lead to fire
or explosion.

⇒ For use only in potentially explosive

atmospheres where oxygen concentrations do
not exceed 20.9% (v/v).

⇒ Extended exposure of the GasAlertMicro to

certain concentrations of combustible gases
and air may stress a detector element, which
can seriously affect its performance. If an
alarm occurs due to high concentration of
combustible gases, recalibration should be
performed, or if needed, the sensor replaced.
