8.
High Impedance Power
a.
Attach a 4000 ohm load between the
ACCESSORY
and
PATIENT
receptacles. Activate cut at maximum power setting and adjust
R61 to achieve approximately 35 W (93 mA). Verify the 3000 ohm
output is above 170 W (238 mA).
b.
Attach a 4000 ohm load between the
ACCESSORY
and
PATIENT
receptacles. Activate blend 2 at maximum power setting and
adjust R62 to obtain approximately 36 W (95 mA). Verify the
3000 ohm output is above 120 W (190 mA).
c.
Attach a 4000 ohm load between the
ACCESSORY
and
PATIENT
receptacles. Activate coag at maximum power setting and adjust
R63 until power increases from approximately 20 W (70 mA) to
58 W (120 mA). Discontinue activation and adjust R63 1/4 turn
counterclockwise. Activate the generator and observe output
reading. Continue this inactivated/activated calibration in 1/4
turn increments until the output is approximately 20 W-26 W
(70 mA-80 mA). Verify the 3000 ohm output is above 60 W
(141 mA).
Use short leads on all connections.
Adjust R61, R62, or R63 if any
reading exceeds 150 mA in the
cut, blend, or coag modes,
respectively. If you need to make
an adjustment, recheck the High-
Impedance power.
9.
High Frequency Leakage
Bipolar RF Leakage
a.
Connect the 200 ohm load and RMS voltmeter in series from the
right
MICROBIPOLAR
receptacle to chassis ground.
b.
Connect a 30 pF capacitor between the left
MICROBIPOLAR
receptacle
and chassis ground.
c.
Activate
MICROBIPOLAR
at 70 W and note the results for the right
MICROBIPOLAR
receptacle.
d.
Reverse the load and capacitor connections at the
MICROBIPOLAR
receptacles.
e.
Activate
MICROBIPOLAR
at 70 W and note the results for the left
MICROBIPOLAR
receptacle.
