Preliminary Performance Testing; Controls, Displays And Connectors; Blend 2 Cut; Blend 3 Cut - ConMed ExcaliburPLUS PC Service Manual

6. Depress the Cut treadle of the monopolar foot
switch. The Return Alarm tone should sound
and Return Fault should continue to glow. While
holding the Cut treadle, rotate the volume control
over its full range and verify there is no signifi-
cant change in sound level. Release the Cut foot
switch and the tone should stop.
7. Verify that each of the following modes can be
selected and adjusted up and down, and that no
other displays are affected:
*Pure Cut
*Blend 1 Cut
*Blend 2 Cut
*Blend 3 Cut
*Standard Coag
*Spray Coag
*Bipolar Coag
«Bipolar Cut
Return all power settings to desired setting.
8. Select Bipolar Coag and depress the bipolar
foot switch. Confirm that the Bipolar Mode indi-
cator illuminates, and a coag activation tone is
sounded, While still depressing the bipolar foot
switch, rotate the Sound Volume Control over it's
full range to verify the function of that control
and that sound is audible at all positions. This
control may be left at any desired position.
Confirm that releasing the bipolar foot switch
returns the Excalibur Plus PC™ to its idle state.
Verify that the bipolar hand switch control is
functional by use of the appropriate forceps or by
connecting a jumper between the center and bot-
tom Bipolar Output jack on the Output Panel.
The effect will be identical to depressing the
Bipolar foot switch.
9. Press the Single Pad Select key to select Single
Pad mode and confirm that no ASSIST
Resistance indicator bars are lit, and the Return
Fault indicator remains lit. Connect a single pad
Return electrode to the Return electrode jack.
Confirm the Return Fault indicator goes out.
10. Depress the Cut treadle of the Monopolar
foot switch. The yellow Cut Mode indicator shall
light and the cut activation tone shall sound.
11. While continuing to press the Cut treadle of
the foot switch, depress the Coag treadle. An
operator error tone shall sound. Release the Cut
treadle, continue to press the Coag treadle and
confirm that the tone changes to the coag activa-
tion tone, and the blue Coag Mode indicator is
illuminated until the Coag treadle is also released.
12. Connect a handswitching active electrode to
the Monopolar Accessory Jack #1. Activate, one
at a time, the Cut and Coag hand switch controls
verifying that each control causes the correct indi-
cator and tone to sound. Move the handswitch-
ing active electrode to the Monopolar Accessory
Jack #2 and repeat.
13. Remove the two wire, single pad return elec-
trode, and confirm that the Excalibur Plus PC™
beeps twice, and the Return Fault indicator illu-
minates.
2.3.2 Preliminary Performance Testing
After the unit passes the Preliminary Functional
Tests of Paragraph 2.3.1, preliminary performance
testing may be conducted. Such testing is best
carried out by use of an electrosurgical generator
tester, as described in this manual. Note that the
power display of the tester will be most accurate
when a noninductive resistor of the rated genera-
tor output impedance for the selected mode is
used.
If no tester is convenient, the availability of thera-
peutic current may be ascertained subjectively by
attempting to cut and coagulate on surrogate tis-
sue such as a piece of meat or fresh fruit, a wet
bar of soap, or a sponge moistened in saline.
