GasAlertMicroClip
Introduction
This quick reference guide provides basic information for the
GasAlertMicroClip. Refer to the user manual on the
accompanying CD-ROM for complete operating instructions.
The GasAlertMicroClip 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 default displayed
language. Additional languages provided are Portuguese,
Spanish, German, and French. The screens for the additional
languages are displayed on the detector and in the
corresponding Quick Reference Guide.
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.
⇒Charge the detector before first-time use. BW
recommends the detector be charged after every
workday.
⇒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

GasAlertMicroClip
Quick Reference Guide
2
every 180 days (6 months).
⇒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.
⇒Only the combustible gas detection portion of
this instrument has been assessed for
performance by CSA International.
⇒Calibrate only in a safe area that is free of
hazardous gas.
⇒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.
⇒Caution: High off-scale readings may indicate an
explosive concentration.
⇒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 GasAlertMicroClip 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.
⇒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).

Calibration
Procedure Display Procedure Display
aCaution
Calibrate only in a safe area and in
an area that is free of hazardous gas.
Do not calibrate the detector during
or immediately after charging is
complete.
1. In a clean atmosphere, press and hold
Cas the detector performs the OFF
countdown. Continue to hold Cwhen
the detector briefly deactivates.
4. Kflashes when you connect the gas
cylinder and apply gas at a flow rate of
250-500 ml/min.
After a sufficient amount of gas has
been detected (approximately 30
seconds) the detector emits a beep
and flashes while the
detector completes the span.
2. The detector then activates again and
performs the CAL countdown.
Continue to hold Cuntil the
countdown is complete to enter
calibration.
5. The LCD then displays CAL DUE. It
then displays the number of days
remaining before the next calibration is
due above each gas. Then the LCD
displays the days until the next
calibration due date before completing
the calibration.
3. flashes while the detector
zeroes all of the sensors and
calibrates the oxygen sensor. If a
sensor failed to auto zero, it cannot be
spanned. Once auto zero is complete,
the LCD displays APPLY GAS.
Note
The calibration cap should only be used during the calibration
span process.
Wind currents may cause false readings and poor calibrations.
Do not calibrate the detector during or immediately after charging
is complete.

Note
Alarms can be set to be latching or non-latching. To confirm this setting, access the latching alarms option in the GasAlertMicroClip
Soft Tools software. Local regulations may require a latching alarm.
If the detector is in stealth mode, it only vibrates in alarm mode (the audible and visual alarms are disabled). If the detector is in IR
stealth mode, the IR LEDs and vibrator activate in alarm mode (the audible alarm is disabled).
If the Low Alarm Acknowledge option is enabled, the beeper can be disabled only during a low alarm by pressing C. The vibrator
and LEDs will function normally. If the alarm escalates to a high, STEL, or TWA alarm, the beeper reactivates.
The backlight activates during any alarm condition.

each sensor.
•Cal Interval: Number of days remaining before the
next calibration.
•Bump Interval: Number of days remaining before the
next bump check.
•Low Alarm: The low alarm setpoint (all sensors).
•High Alarm: The high alarm setpoint (all sensors).
•TWA Alarm: The time-weighted average (TWA)
alarm setpoint (toxic sensors only).
•STEL Alarm: The short-term exposure limit (STEL)
alarm setpoint (toxic sensors only).
•STEL Interval: Changes the short-term exposure
limit (5-15 minutes; applicable to toxic sensors only).

remain active until the user acknowledges the alarm.
•Safe Mode: Enables the LCD to display Safe if the
detector does not enter an alarm.
•Stealth Mode: When enabled, the beeper, backlight,
and alarm LEDs are disabled. Only the vibrator
activates.
•IR Stealth Mode: When enabled, the beeper and

activate.

GasAlertMicroClip
Charging the Detector
•Low Alarm Acknowledge: When enabled, the
beeper can be disabled during low alarm if Cis
pressed. The vibrator and alarm LEDs will function
normally (H2S, CO, and LEL sensors only);
The battery should be charged after each workday. To charge
the battery, deactivate the detector and insert the
GasAlertMicroClip charging adapter (as shown in the following
figure). Allow it to charge for 2-3 hours.
•Force Calibration When Overdue: Forces the
detector into mandatory calibration if a sensor is
overdue for calibration upon start-up;
The detector must be charged in a non-hazardous atmosphere
of 0°C-45°C (32°F-113°F).
To reach full battery capacity, allow the battery to fully charge
and fully discharge three times.
•Cal Lock: It allows the detector to auto zero, but span
needs to be conducted with an IR device;
•Force Bump When Overdue: Forces a bump check
if the sensor has exceeded its bump check interval;
•Bump Due Lock: Forces the detector to search for
an IR device to execute a bump check.
3. Language
Enables the LCD’s language in English, French
(Français), German (Deutsch), Spanish (Español), or
Portuguese (Português).
Charging the Detector
aWarning
The battery can only be replaced by the manufacturer.
Not complying with this might cause explosion danger.

DAILY BUMP TEST
iERP: 125538
BW recommends to “bump test” the
sensor(s), before each day’s use to confirm
their ability to respond to gas by expos-
ing the detector to a gas concentration that
exceeds the alarm setpoints. Manually verify
that the audible and visual alarms are
activated.
If any sensor fails the bump test, contact
your local BW service department immedi-
ately.
aIMPORTANT NOTE
