5. Bipolar Coagulation - (Load - 100 ohms)
• Set the power to 20W - Activate Bipolar
and verify the power is 20W (15W -
25W).
• Set the power to 70 ohm - Activate
Bipolar and verify the power is 70W
(62W - 77W).
6. Argon Beam Coagulation - (Load - 500
ohms)
• Set the power to 20W - Activate ABC™
and verify the power is 20W (16W -
24W).
• Set the power to 150W - Activate ABC™
and verify the power is 150W (135W-
165W).
7.7.5 Argon Flow Testing
A mass flow meter calibrated for argon gas is
required to measure and verify argon flow rates.
However, if a flow meter is not available, the flow
can be tested and verified so as the flow setting
is increased, the flow rate increases. An ABC™
accessory is required to test the argon flow rate.
In the previous section for Display Panel testing,
three (3) tables listed flow limits as related to
ABC™ power settings. Refer back to the tables or
keep in mind that when the argon setting does not
increase or decrease beyond present settings, the
ABC™ power is forcing the limit.
Smart Sense can change the initial flow setting
during an activation interval if the back pres
-
sure caused by the accessory or any other type of
partial occlusion exceeds internal limits. When
testing the flow rates, the measured flow should
match that of the displayed flow rate.
1. Without an Argon Calibrated Mass Flow
Meter:
• Select Manual flow mode. Set the flow
to 4 slpm and power to 50W. Activate
ABC™ into a 500 ohm load. The flow of
the argon will typically be audible, but a
beam will only occur if the gas is flowing.
A typical beam length at these settings is
close to 1cm.
• Increase the flow in increments of 1 slpm
and for each setting, activate into a load.
Verify a beam occurs and has a length
greater than 5mm. To get more than 8
slpm of flow, the power must be greater
than 80W.
2. With an Argon Calibrated Flow Meter:
• Insure the nozzle of the ABC accessory is
seated within the intake hose of the meter
to minimize leaking. A leak in the con
-
nection will give false readings.
• Flow should be checked at 2, 4, & 8 slpm
as a minimum. The flow is calibrated at
the factory and is within specifications if
the flow is
±.6 slpm. If the flow rate is
not correct, go to the calibration section
of this manual.
7.7.6 Remote Power Control Testing
A standard “2 button” handcontrol is sufficient
to test the Remote Power Control, however it
will only allow testing of Cut and Coag modes.
ABC™ Remote Power Control can be tested with
a Triple Option ABC™ accessory.
1. Press the “Remote” front panel switch.
Ensure a handcontrol is connected to either
Monopolar Handcontrol or Beam/Monopolar
Handcontrol jacks. (ABC™ handswitchable
accessories must be connected to the Beam/
Monopolar Handcontrol jacks.)
2. Rapidly “double press” or “double click” the
CUT (yellow) button on the handcontrol.
The Cut display will flash when the Remote
Power mode is active and the tone will
change. (If the displays do not flash, it typi
-
cally means the double press did not occur
within a specified time of 400mS. Try the
function again.)
• To advance the power setting, press the
Cut button - to reduce the power setting,
press the Coag button.
• With the power <20W, the power changes
in 1W increments.
• With the power ≥ 20W, the power chang-
es in 5W increments.
• A brief tone occurs each time the power
changes.
• To exit the Remote Mode, double press
the Cut button or wait 5 seconds and the
system will automatically exit the Remote
Mode.
3. Rapidly “double press” or “double click” the
COAG (blue) button on the handcontrol.
The Coag display will flash when the Remote
Power mode is active and the tone will
change. (If the displays do not flash, it typi
