product that is returned to a BW authorized service center within the warranty period. In no event shall BW’s liability hereunder exceed the
purchase price actually paid by the buyer for the Product. This warranty does not include:
a) fuses, disposable batteries or the routine replacement of parts due to the normal wear and tear of the product arising from
use;
b) any product which in BW’s opinion, has been misused, altered, neglected or damaged by accident or abnormal conditions of
operation, handling or use;
c) any damage or defects attributable to repair of the product by any person other than an authorized dealer, or the installation
of unapproved parts on the product; or
The obligations set forth in this warranty are conditional on:
a) proper storage, installation, calibration, use, maintenance and compliance with the product manual instructions and any other
applicable recommendations of BW;
b) the buyer promptly notifying BW of any defect and, if required, promptly making the product available for correction. No

c) the right of BW to require that the buyer provide proof of purchase such as the original invoice, bill of sale, or packing slip to
establish that the product is within the warranty period.
THE BUYER AGREES THAT THIS WARRANTY IS THE BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. BW SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR
CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, WHETHER ARISING FROM BREACH OF WARRANTY OR
BASED ON CONTRACT, TORT OR RELIANCE OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion, or limitation of incidental or
consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any provision of this warranty is

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.
aCautions
⇒ 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).
* See Specifications

⇒ 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.
⇒ 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.

Calibration
Procedure Display Procedure Display
1. In a clean atmosphere, press C
and Hsimultaneously and hold for
5 seconds. The detector beeps
4 times. The detector then beeps
once more signifying that
calibration has started.
4. Press Hor Gto change the alarm
setpoint. Press Ato skip to the
next setpoint. Press Cto save.
The detector beeps four times at
the end of the alarm setpoint stage.
2. The display flashes N while
the detector zeroes the H2S, CO,
and combustible sensors. The
detector beeps twice at the end of
the auto zero stage.
5. Press Hor Gto change the next
calibration due date. Press Cto
save. The detector beeps five times
indicating that calibration is
complete.
3. When the display flashes K,
connect the calibration bottle and
apply gas at a flow rate of 250 to
500 ml/min. The detector beeps
three times at the end of the span
stage. Remove the calibration gas.
Note
The calibration cap should only be used during the
calibration process.
