Instruction manual

NOTICE: CAUTION: This safety symbol is used to
indicate a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
NOTICE: LEL sensor should be checked for accuracy after
exposure to any gases containing silicones, high sulfur content,
high concentrations of propane and high concentrations of CO
(above 1000ppm) or exhaust gases.
Continuously low calibration check results or fluctuation of zero
readings may indicate sensor end of life or failure. Consult SENSIT
Technologies with any questions.
For best accuracy always zero in clean air environments similar in
temperature and relative humidity to the environment where the
instrument will be used. When continuously exposed to
combustible gas concentrations beyond LEL for longer than 5
minutes always perform a calibration check prior to the next use.
WARNING: To reduce the risk of ignition of a flammable
atmosphere, batteries must only be changed in an area known
to be nonflammable.
WARNING: Do not mix batteries of different age or type.
WARNING: Not for use in atmospheres of oxygen greater
than 21%.
WARNING:
ONLY zero instrument in a gas free environment.
WARNING: To maintain intrinsic safety, service must be
performed by factory authorized technicians with approved
replacement parts only.
