4) Disconnect the ESU tester from the unit.
5) Use test leads to connect the ESU tester to
the Bipolar Accessory outputs.
6) Perform the bipolar power tests indicated in
Table 4.3. This table only provides the mini-
mum number of points to be tested.

4.6.4 RF Leakage Measurement
RF Leakage can present a hazard in the operating
room because electrosurgical currents can flow
to the patient and operating room staff through
unintended paths, which can cause injury. RF
leakage occurs because the total energy in the
output voltage waveform is provided with a con-
ductive path through stray parasitic capacitance
distributed within the generator and along the
length of the leads. Table 4.4 presents the allowed
RF leakage currents to ground.
