Checking Monopolar High Frequency Leakage Current
1.
Connect the 200 Ω load from the active accessory through the current transformer to
the equipotential ground lug on the rear of the generator.
2.
Connect the current transformer to a true RMS voltmeter.
3.
Connect a monopolar footswitch to the Monopolar 1 Footswitch receptacle on the
rear panel.
4.
Activate the footswitch in each Monopolar mode at the maximum control setting.
Record the leakage current. If using the leakage table, leakage current should not
exceed 150 mA for any mode.
5.
If the high frequency leakage exceeds 150 mA, call the Covidien Service Center for
further instructions.
Checking Bipolar High Frequency Leakage Current
1.
Remove the monopolar accessories, and connect the 200 Ω load from one side of the
bipolar output through the current transformer to the equipotential ground lug on
the rear of the generator.
2.
Connect the current transformer to the true RMS voltmeter.
3.
Connect a bipolar footswitch to the Bipolar Footswitch receptacle on the rear panel.
4.
Activate the footswitch in each mode at maximum control setting. Record the
leakage current. It should not exceed 60 mA for any mode using either the leakage
table or short lead configuration.
5.
If the high frequency leakage exceeds 60 mA, call the Covidien Service Center for
further instructions.
