USER MANUAL
Note: CSA have only assessed the LEL combustible gas detection portion of this
monitor for performance.
Note: CSA a seulement évalué la partie LIE pour la mesure des performances en
détection de gaz inflammables.
Note: The monitor performs 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.
1.2.2 Certification and Approvals
The monitor has the following approvals:
