from electrical ground and all other conductive circuits
Notes
in the cardiograph. This reduces the possibility of
hazardous currents passing from the cardiograph through
the patient's heart to ground. To ensure the patient's
safety and your own, observe the following reminders.
When operating your cardiograph from AC power, be
sure it and all other electrical equipment connected to
or near the patient are effectively grounded.
Use only grounded power cords (three-wire power
cords with grounded plugs). Also make sure the
outlet accepts the plug and is grounded. Never
modify a grounded plug to fit an ungrounded outlet,
i.e. removing the ground prong or ground clip to
fit an ungrounded outlet. Should an ungrounded
plug adapter be necessary, use a ground strap to
connect the equipotential connector at the rear of the
instrument to the power source ground.
The patient cable should be routed away from power
cords and any other electrical equipment. Failure to do
so can result in AC line frequency interference on the
ECG trace.
Warning The HP patient cable supplied with this cardiograph, or an
approved HP substitute patient cable, is an integral part
of the cardiograph's safety features. Using any other
patient cable may compromise defibrillation protection as
well as performance.
Only qualified personnel may service the cardiograph.
