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

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).

GasAlertMicro 5 & GasAlertMicro 5 PID

Quick Reference Guide

⇒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

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.

For complete information and procedures, refer to the

GasAlertMicro 5/PID/IR User Manual.
