Verify the calibration of the combustible gas sensor after any
incident where the combustible gas content has caused the
instrument to display an over-range condition.
Silicone compound vapors or other known contaminants may
affect the combustible gas sensor and cause readings of
combustible gas to be lower than actual gas concentrations. If
the instrument has been used in an area where silicone vapors
were present, always calibrate the instrument before next use to
ensure accurate measurements.
Sensor openings and water barriers must be kept clean.
Obstruction of the sensor openings and/or contamination of the
water barriers may cause readings to be lower than actual gas
concentrations.
Sudden changes in atmospheric pressure may cause temporary
fluctuations in the oxygen reading.
Charge battery, service unit, and use its communication port
only in non-hazardous locations. Not for use in oxygen-enriched
atmospheres.
WARNING: Substitution of components may impair intrinsic
safety and may cause an unsafe condition.
AVERTISSEMENT: La substitution de composants peut
compomettre la securite intrinseque.
CAUTION: For safety reasons, this equipment must be operated
and serviced by qualified personnel only. Read and understand
the instruction manual completely before operating or servicing.
ATTENTION: Pour des raisons de sécurité, cet équipment doit
étre utilesé entretenu et réparé uniquement par un personnel
qualifié. Étudier le manuel d'instructions en entier avant d'utiliser,
d'entretenir ou de réparer l'équipement.
CAUTION: High off-scale readings may indicate explosive
concentration.
ATTENTION: Des lectrures supérieures a l'échelle peuvent
indiquer des concentrations explosives.
