ADDITIONAL SAFETY DETAILS - CSA ONLY
CAUTION: Before each days Usage, test on a known concentration of methane,
equivalent to 25 - 50% of full scale concentration. Accuracy must be within
0 to +20% of actual. Accuracy may be corrected by calibration. (Refer to
Chapter 7 : ‘CALIBRATION’).
ATTENTION: Avant chaque utilisation journalière, testez la réaction de l’appareil
en utilisant une concentration connue en méthane, correspondant à 25-50%
de la lecture à fond d’échelle. La précision doit se situer entre 0 et +20% de la
valeur réelle. La précision peut se corriger en étalonnant l’appareil (voir Chapitre
7 : CALIBRATION).
CAUTION: Any rapid up-scale readings followed by a declining or erratic reading
may indicate a gas concentration beyond the upper scale limit, which may be
hazardous.
ATTENTION: Toute lecture dépassant rapidement le maximum de l’échelle et
suivie par une diminution ou une lecture erronée, indique une concentration
de gaz supérieure à la valeur maximale de cette échelle. Cette lecture n’est
pas significative.
NOTE: CSA have only assessed the LEL combustible gas detection portion of
this instrument for performance.
NOTE : CSA a seulement évalué la partie LIE pour la mesure des performances
en détection de gaz inflammables.
NOTE: The instrument contains internal checking of sensor sensitivity, which
during calibration will prevent the sensor being calibrated if it has been
contaminated or reached its end of life. In addition to this the Instrument
Management System (IMS) can be used to track the condition of sensors from
stored calibration results.

AREAS OF USE
Exposure to certain chemicals can result in a loss of sensitivity of the flammable
sensor. Where such environments are known or suspected it is recommended
that more frequent response checks are carried out. (Refer to Chapter 3:
‘MANUAL BUMP TEST’). Chemical compounds that can cause loss of sensitivity
include Silicones, Lead, Halogens and Sulphur.
Do not use instrument in potentially hazardous atmospheres containing greater
than 21% Oxygen.
SPECIAL CONDITIONS OF USE No precautions against electrostatic discharge are necessary for portable
equipment that has an enclosure made of plastic, met
the two, except where a significant static generating mechanism has been
identified. Activities such as placing the item in a pocket or on a belt, operating
a keypad or cleaning with a damp cloth, do not present a significant electrostatic
risk. However, where a static-generating mechanism is identified, such as
repeated brushing against clothing, then suitable precautions shall be taken,
e.g. the use of anti-static footwear.
STORAGE, HANDLING AND TRANSIT The instrument is designed to handle harsh environments. The instrument is
sealed to IP67 and, if not subjected to misuse or malicious damage, will provide
many years of reliable service.
The instrument can contain electrochemical sensors. Under conditions of
prolonged storage these sensors should be removed. The sensor contains
potentially corrosive liquid and care should be taken when handling or disposing
of the sensor, particularly when a leak is suspected.
