Cautions (cont.)
⇒
The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different combustible gas in the
% LEL range, calibrate the sensor using the appropriate gas. High off-scale % LEL or % v/v methane readings may
indicate an explosive concentration.
⇒
Protect the combustible sensor from exposure to lead compounds, silicones and chlorinated hydrocarbons.
Although certain organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit
sensor performance, in most cases, the sensor will recover after calibration.
⇒
Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond
upper scale limit, which may be hazardous.
⇒
Use only recommended AA alkaline or NiMH batteries properly charged, and installed in the detector case. (See
the section “Replacement Parts and Accessories.”)
⇒
Charge NiMH batteries using recommended charger only. Do not use any other charger. Failure to observe this
precaution could lead to fire or explosion.
⇒
Do not change or charge batteries in a hazardous location. Doing so will impair the Intrinsic Safety of the unit and
may lead to fire or explosion.
⇒
Read and observe all instructions and precautions in the literature provided with the charger. Failure to do so may
result in fire, electric shock or other forms of personal injury or property damage.
