I Safety Information
Explosive Gases
WARNING!
Do not use the Model 908A Dual Capacitance Diaphragm Gauge Con-
troller to measure the pressure of combustible gas mixtures. The gauge
normally operates at low temperatures, but it is possible that momen-
tary transients or controller malfunction may cause ignition of combus-
tible mixtures, which then might explode and cause damage to
equipment and injury to personnel.
Limitation on use of Compression Mounts
WARNING!
Do not use a compression mount (quick-connect) for attaching the
gauge tube to the vacuum system in applications that may develop pos-
itive pressures. Positive pressures may cause the tube to be blown out
of a compression fitting and damage equipment and injure personnel.
Chemicals
WARNING!
Many organic cleaning solvents, such as acetone, produce fumes that
are toxic or flammable. Use such solvents only in areas that are well
ventilated to the outdoors and away from electronic equipment, open
flames, or other potential ignition sources.
