Force FX Electrosurgical Generator C Service Manual
c.
Connect the 100 Ω power resistor across the output jacks at the end of the test
cables.
d.
Connect the bipolar footswitch to the Bipolar Footswitch receptacle on the rear
panel.
3.
Press the Precise button and set the bipolar power to 10 W.
4.
Test the output current for the selected Bipolar mode.
a.
Press the footswitch pedal and, while activating the generator, note the output on
the voltmeter.
b.
Release the footswitch pedal.
c.
Based on the voltmeter setting and the current transformer you are using,
calculate and record the output current.
5.
Press the Standard button and repeat step 4 (above).
6.
Press the Macro button and repeat step 4 (above).
7.
Verify that the generator output for each mode is 315 ± 24 mA
rms
.
If the output is outside the specified range, calibrate the bipolar output as described
in
Calibrating the Generator
on page 5-26. Then repeat this procedure. If the output
for one or more modes remains outside the specified range, call the Covidien Service
Center.
Checking Output for the Monopolar Cut Modes
1.
Verify that the generator successfully completes the self-test as described in
Generator Self-test
on page 5-18
.
2.
Connect the test equipment for monopolar output.
a.
Connect one test cable to the left jack in the Monopolar 1/CEM Instrument
receptacle. Pass the test cable through the current transformer and connect the
current transformer to the voltmeter.
b.
Use a test cable to short the two pins on the Patient Return Electrode receptacle.
c.
Connect the second test cable from the voltmeter to both pins of the Patient
Return Electrode receptacle.
d.
Connect the 300 Ω resistor across the output jacks at the end of the test cables.
e.
Connect the monopolar footswitch to the Monopolar 1 Footswitch receptacle on
the rear panel of the generator.
3.
Press the Pure button.
4.
Press the Cut up (

) or down (

) arrow buttons to set the cut power to 75 W.
5.
Test the monopolar cut output.
a.
Press the footswitch cut pedal and, while activating the generator, note the
output on the voltmeter.
