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.

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.

Note

Zeroing the Sensors

To zero the sensors, refer to steps #1-3 in Calibration on page 7.

ec Warning

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

2

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

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).

GasAlertMicroClip

Operator’s Manual

recommande de recharger le détecteur après chaque
journée d’utilisation.

• Avant toute utilisation du détecteur, reportez-vous à la
section .

• Étalonnez le détecteur avant sa première utilisation,
puis de manière régulière, en fonction de l’utilisation et
de l’exposition du capteur aux poisons et autres
contaminants. BW recommande d'effectuer un
étalonnage au moins une fois tous les 180 jours
(6 mois).

• Le capteur de gaz combustibles est étalonné en usine
au méthane, à une concentration de 50 % de la LIE. Si le
contrôle porte sur un autre gaz combustible dans la
plage de % LIE, étalonnez le capteur en utilisant le gaz
approprié.

• Sur cet appareil, seule la détection de gaz combustibles
a fait l’objet d’une évaluation des performances par
CSA International.

• Veillez à effectuer l'étalonnage dans une zone sûre,
exempte de gaz dangereux, et dans une atmosphère
contenant 20,9 % d'oxygène.

• Si le capteur de gaz combustibles a été exposé à des
contaminants/poisons (composés de soufre, vapeurs de
silicium, produits halogénés, etc.), il est conseillé de
vérifier son bon fonctionnement en le mettant en
présence d'une concentration connue d'un gaz.

4

• Avant chaque utilisation quotidienne, BW recommande
d’effectuer un test fonctionnel des capteurs afin de
vérifier qu’ils réagissent bien aux gaz présents, en
exposant le détecteur à une concentration de gaz
supérieure aux seuils d’alarme. Vérifiez manuellement
que les alarmes sonore et visuelle sont activées.
Étalonnez l’appareil si les relevés ne sont pas
conformes aux limites spécifiées.

• Mise en garde : Des relevés élevés hors échelle peuvent
indiquer la présence d’une concentration explosive.

• Toute mesure en rapide augmentation suivie d’une
diminution ou d’une mesure fantaisiste peut indiquer
une concentration de gaz au-delà de la limite d’échelle
supérieure, risquant donc d’être dangereuse.

• Une exposition prolongée du GasAlertMicroClip XT à
certaines concentrations de gaz combustibles et dans
certaines atmosphères peut nuire à l'élément de
détection et altérer gravement ses performances.
Étalonnez le détecteur après toute exposition à des
concentrations élevées de gaz combustibles ayant
déclenché son alarme. Si nécessaire, remplacez le
capteur.

• Protégez le capteur de gaz combustibles contre toute
exposition aux composés de plomb, aux silicones et
aux hydrocarbures chlorés.

• L'exposition du capteur à certaines vapeurs organiques

(comme l'essence au plomb ou les hydrocarbures
halogénés) peut altérer temporairement son bon
fonctionnement. Il est recommandé de procéder à un
test fonctionnel ou à un étalonnage après toute
exposition.

• Cet appareil est destiné uniquement à une utilisation
dans des atmosphères potentiellement explosives,
dans lesquelles la concentration d’oxygène ne dépasse
pas 20,9 % (v/v).
