period of two years, beginning on the date of shipment to the buyer. This warranty extends only to the sale of new and unused products to
the original buyer. BW’s warranty obligation is limited, at BW’s option, to refund of the purchase price, repair, or replacement of a defective
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
goods shall be returned to BW until receipt by the buyer of shipping instructions from BW; and
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 5 & GasAlertMicro 5 PID
Introduction
This quick reference guide provides basic information for the
GasAlertMicro 5 and GasAlertMicro 5 PID. Refer to the user
manual on the accompanying CD-ROM for complete operating
instructions. The GasAlertMicro 5 and GasAlertMicro 5 PID 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).

⇒It is recommended that the combustible
sensor be checked with a known
concentration of calibration gas after any
known exposure to contaminants/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
p
erformance
,
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
may be hazardous.
⇒Extended exposure of the GasAlertMicro 5 and
GasAlertMicro 5 PID 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 a
high concentration of combustible gases,
recalibration should be performed, or if
needed, the sensor replaced.
⇒Protect the PID sensor from exposure to
silicone vapors.
⇒The BW pump module (M5-PUMP) is certified for
use with the GasAlertMicro 5 and GasAlertMicro
5 PID only.

Calibration
Procedure Display Procedure Display
1. In a clean atmosphere, press and hold
Cand Hsimultaneously (as the
detector beeps and flashes to the
corresponding countdown) to enter
calibration. The detector then reads
Starting calibration.
4. This option allows the user to select
which sensor to span. Use Gand H
to scroll to a sensor and press Cto
deselect it.
Sensors should be spanned in the
following order: exotics (NH3, ClO2, O3,
and Cl2), single gas, quad gas (H2S,
CO, O2, and LEL), and lastly PID.
2. flashes while the detector
zeroes all of the sensors and
calibrates the oxygen sensor. If a
sensor failed to auto zero, it will
bypass the span.
5. Attach the calibration cap and apply
gas at a flow rate of 500 ml/min.
Kflashes as the unit senses which gas
is being applied.
After 30 seconds, flashes
and a countdown appears while the
unit completes the span.
3. Next, the following three screens
appear:
- Apply span gas now to calibrate
- or press Cto select sensor(s)
- or press Ato skip calibration
If no button is pressed, proceed to step
#5. If Cis pressed, go to step #4. If A
is pressed, go to the end of step #6.
6. Once the span is complete, the
following three screens appear:
- Calibration successful
- Press Gto apply a new cal gas
- Press Hto end span
Repeat steps #3-6 to calibrate the
remaining sensors.
The display then advises to press Cto
set or Ato bypass the calibration due
dates.

Procedure Display
7. Press Hor Gto change the
calibration due date. Press Cto
accept this value and proceed to the
next due date. (If a sensor failed or
did not span, you cannot change
the calibration due date for that
sensor.)
The display then advises to press
Cto set or Ato bypass the alarm
setpoints.
8. Press Hor Gto change the alarm
setpoint. Press Cto save the
displayed value and proceed to the
next setpoint. Set the remaining
setpoints. The detector beeps twice
at the end of the alarm setpoint
stage.
9. Saving calibration displays to
indicate that calibration is complete.
Note
The calibration cap should
only be used during the
calibration process.
Attach the Gas Cylinder to the Detector
If an O3or ClO2sensor is located in the Toxic 2 sensor
position, a single gas calibration cap must be used.
