Situation Possible cause Recommended action
Continuous monitor interference Faulty chassis-to-ground connections 1.
2.
Check and correct the chassis ground
connections for the monitor and, if applicable,
for the generator.
Check other electrical equipment in the room
for defective grounds.
Electrical equipment is grounded to
different objects rather than a common
ground.
The 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 Coagulation 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.
