Safety Information
High Voltage
WARNING!
The Terranova 921 Cold Cathode Gauge Controller supplies a high voltage
of 4,000 volts to the HPS Inverted Magnetron Gauge Head when the “Hi
Volt Gauge on” is activated. Be sure that the Hi Volt light is off and/or that
the power is removed from the Terranova 921 Controller before connecting
or disconnecting either end of the gauge cable.
Combustible Gases
WARNING!
Do not use the Terranova 921 Cold Cathode Gauge Controller / Display to
measure the pressure of combustible gas mixtures. The gauge operates with
an ionized gas discharge, and it is possible that this discharge may cause ig-
nition of combustible mixtures, which then might explode and cause dam-
age to equipment and injury to 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.
