Checking Monopolar Coag Output
1.
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.
Verify that the monopolar footswitch is connected to the Monopolar 1 Footswitch
receptacle on the rear panel.
e.
Connect the 500 Ω resistor across the output jacks at the end of the test cables.
2.
Press the Desiccate button.
3.
Check the ECON for the selected coag mode.
a.
Verify that "10" appears in the Coag display.
b.
Press the footswitch coag pedal and, while activating the generator, press the
Coag up (

) or down (

) arrow buttons until the voltmeter reading is equivalent
to 141 ± 9 mA
rms
. Ignore changes to the Coag display
.

d.
Press the coag pedal again and, while activating the generator, press the Coag up
(

) or down (

) arrow buttons until the voltmeter reading is equivalent to
489 ± 5 mA
rms
. Ignore changes to the Coag display.
e.
Stop activation. Verify that the Coag display changed to 10.
4.
To check the Fulgurate mode, press the Fulgurate button and repeat step 3 (above).
a.
If a “0” (zero) appears in the Cut display and a “10” appears in the coag display,
repeat step 3. This completes LCF Fulgurate mode calibration.
b.
Press the Med (Fulgurate) button. Verify that an “H” appears in the Cut display
and a “10” appears in the coag display. Repeat step 3. This completes Fulgurate
mode calibration.
