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.
a
Cautions
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
Page 4
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
a
Caution
Calibrate only in a safe area that is free of hazardous gas in an atmosphere of 20.9% oxygen.
1. Press and hold C as the detector
performs the OFF countdown. Continue holding C when 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 C until 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)
Ɣ To ensure an accurate bump check, use a premium-grade gas. Use gases
approved by the National Institute of Standards and Technology.
Ɣ Do not use a gas cylinder that is past its expiration date.
Note
Only use the calibration cap during calibration and bump check.

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 counter­clockwise 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.
