FOR SAFETY REASONS THIS EQUIPMENT MUST BE OPERATED AND SERVICED
l
BY QUALIFIED PERSONNEL ONLY. READ AND UNDERSTAND INSTRUCTION
MANUAL COMPLETELY BEFORE OPERATING OR SERVICING.
Substitution of components may impair Intrinsic Safety.
l
Protect the combustible sensor from exposure to lead compounds, silicones, and
l
chlorinated hydrocarbons. Although certain organic vapors (such as leaded
gasoline and halogenated hydrocarbons) can temporarily inhibit sensor
performance, in most cases the sensor will recover after calibration.
The Canadian Standards Association (CSA) requires the LEL sensor to be bump
l
tested before each day's use with calibration gas containing between 25% and
50% LEL. The instrument must be calibrated if the displayed LEL value during a
bump test fails to fall between 100% and 120% of the expected value for the gas.
High off-scale LEL readings may indicate an explosive concentration.
l
Any rapid up scaling reading followed by a declining or erratic reading may
l
indicate a gas concentration beyond the upper scale limit, which can be
hazardous.
Products may contain materials that are regulated for transportation under
l
domestic and international dangerous goods regulations. Return product in
compliance with appropriate dangerous goods regulations. Contact freight carrier
for further instructions.
Dispose of used lithium cells immediately. Do not disassemble and do not dispose
l
of in fire. Do not mix batteries with the solid waste stream. Spent batteries should
be disposed of by a qualified recycler or hazardous materials handler. Keep
children away from the lithium cells.
The pellistors used in the Catalytic flammable gas sensor can suffer from a loss of
l
sensitivity when in the presence of poisons or inhibitors, e.g. silicones, sulphides,
chlorine, lead or halogenated hydrocarbons.
DO NOT rely on the Bluetooth BW™ Ultra output indication for security purposes.
l
DO NOT use the screen protector in the hazardous location. The screen protector
l
must be removed in the explosive atmospheres.
The accessories (e.g., fitting mini quick-connector to 1/8", fitting male Luer-lock to
l
1/8" etc.) are not the scope of intrinsic safe certification
Do not install or remove any components when an explosive gas atmosphere is
l
present.
