SurgiStat Low-Power Electrosurgical Generator Service Manual 7-9
Correcting Common Problems
Continuous monitor
interference Faulty chassis-to-ground
connections 1) Check and correct the chassis
ground connections for the
monitor and, if applicable, for
the generator.
2) Check other electrical
equipment in the room for
defective grounds.
Electrical equipment is
grounded to different objects
rather than a common ground
Generator may respond to the
resulting voltage differences
between grounded objects
Plug all electrical equipment into
line power at the same location.
Malfunctioning monitor Replace the monitor.
Interference with other
devices only when
generator is activated Metal-to-metal sparking Check all connections to the
generator, patient return electrode,
and accessories.
High settings used for
fulguration Use lower power settings for
fulguration or select the Desiccate
mode.
Electrically inconsistent ground
wires in the operating room Verify that all ground wires are as
short as possible and go to the same
grounded metal.
If interference continues when
the generator is activated, the
monitor is responding to
radiated frequencies Check with the manufacturer of the
monitor.
Some manufacturers offer RF choke
filters for use in monitor leads.
The filters reduce interference when
the generator is activated and
minimize the potential for an
electrosurgical burn at the site of
the monitor electrode.
