GasAlertMicroClip
Introduction
The operator’s manual provides basic information for the
GasAlertMicroClip XT and XL. For complete operating
instructions, refer to the GasAlertMicroClip Technical Reference
Guide provided on the CD-ROM. The GasAlertMicroClip (“the
detector”) warns of hazardous gas at levels above user-defined
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 operator s manuals.
Zeroing the Sensors
To zero the sensors, refer to steps #1-3 in Calibration on page 7.
ec Warning
This instrument contains a lithium polymer battery.
Dispose of lithium cells immediately. Do not disassemble
and do not dispose of in fire. Do not mix with the solid
waste stream. Spent batteries should be disposed of by a
qualified recycler or hazardous materials handler.

Safety Information - Read First
Use the detector only as specified in this manual and the
reference 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.
• Before using the detector, refer to Sensor Poisons and
Contaminants.
• 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 calibrating at least once 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 and in an atmosphere of 20.9% oxygen.
• It is recommended that the combustible sensor be
checked with a known concentration of calibration gas
after any exposure to contaminants/poisons such as,
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 the upper scale limit, which can be hazardous.
• Extended exposure of the GasAlertMicroClip to certain
concentrations of combustible gases and air may stress
a detector element that can seriously affect its

GasAlertMicroClip
performance. If an alarm occurs due to a high
concentration of combustible gases, calibrate the
detector. If necessary, replace the sensor.
• Protect the combustible sensor from exposure to lead
compounds, silicones, and chlorinated hydrocarbons.
• Sensor exposure to certain organic vapors (such as
leaded gasoline and halogenated hydrocarbons) may
temporarily inhibit sensor performance. After exposure,
a bump test or calibration is recommended.
• 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 that is free of
hazardous gas in an atmosphere of 20.9%
oxygen.
1. Press and hold Cas the detector
performs the OFF countdown. Continue
holding Cwhen the LCD briefly
deactivates.
4. When is displayed and
flashes, connect the gas cylinder (refer to
page 11) and apply gas at a flow rate of
250 to 500 ml/min.
After a sufficient amount of gas has been
detected (approximately 30 seconds), the
detector beeps and flashes
while the detector completes the
calibration.
2. The LCD then activates again and
performs the CAL countdown. Continue
holding Cuntil the countdown is complete
to enter calibration.
5. The LCD displays CAL DUE. Next, a
screen displays showing the number of
days remaining before calibration is due
for each sensor. The LCD then displays
the earliest calibration due date, as some
sensors require more frequent
calibrations.
3. flashes while the detector
zeroes all of the sensors and calibrates the
oxygen sensor. If a sensor fails to auto
zero, it cannot be calibrated. When auto
zero is complete, the LCD displays APPLY
GAS.
Note Only use the calibration cap during the calibration
span process and for bump tests.
Wind currents may cause false readings and poor calibrations.
Do not calibrate the detector during or immediately after
charging is complete.

Bump Test
Gas Cylinder Connection
1. Connect the calibration hose to the 0.5 l/min regulator on the gas cylinder.
For use with the MicroDock II, use a demand flow regulator.
NOTE: Cylinders that are used with a demand flow regulator must meet
the following maximum inlet pressure specifications:
- Disposable cylinders 0-1000 psig/70 bar
- Refillable cylinders 0-3000 psig/207 bar
To perform an automated bump check, refer to the MicroDock II User Manual.
2. Connect the calibration hose to the calibration cap.
3. Attach the calibration cap to the detector.
4. Apply gas. Verify the visual and audible alarms activate.
5. Close the regulator and remove the calibration cap from the detector.
NOTE: The detector will temporarily remain in alarm until the gas clears from
the sensors.
6. Disconnect the hose from the calibration cap and the regulator.
Gas Cylinder Guidelines (Bump Test)
ƔTo ensure an accurate bump check, use a premium-grade gas. Use gases
approved by the National Institute of Standards and Technology.
ƔDo not use a gas cylinder that is past its expiration date.
Note
Only use the calibration
cap during calibration
and bump check.

tear the flex cable.
2. Note the placement of the PCB to ensure it is
replaced correctly. Remove the two screws on the
PCB.
aCaution
Ensure no damage occurs to the battery.

in the front shell. Remove the sensor.
4. On roughly the same spot on the front shell, place the
new sensor. Lower the PCB over the oxygen sensor.
5. Ensure the plastic sensor post is inserted into the
clear plastic hole. Carefully replace the circular
rigidified flex PCB atop the metal sensor posts. Take
care not to tear the flex cable.
6. Press down to secure the circular rigidified flex PCB
atop the metal sensor posts.
7. To complete the detector, refer to Reassembling the
detector.
Reassembling the detector
• Verify the PCB is seated correctly and inserted exactly as
it was removed (sensors face the front shell). Replace the
two PCB screws.
• Visually inspect the battery to ensure no damage has
occurred.
• When replacing the rear shell, ensure the charging pins
(bottom of inside rear shell) are aligned with the
corresponding holes on the PCB.
• Press the front and rear shells together firmly to ensure a
proper seal. Ensure the front and rear shell have a
uniform, tight 1/16 in. (1 mm) seal on all sides of the
detector.
• When replacing the screws, they must be seated properly
to prevent cross threading. Turn the screw counter-
clockwise until a click is heard and then begin tightening
the screw clockwise.
• New sensor(s) should be calibrated. Activate the detector
and calibrate the sensor(s). Refer to Calibration.
Note
Ensure the rib on the interior rear shell inserts
between the battery and the PCB . Refer to the
following illustrations.
