c.
Connect the 50 ohm 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.
or
Connect the monopolar footswitch to the Footswitch receptacle on the front
panel and press the Footswitch Selector button until the left arrow indicator
illuminates green.
Start with a low Z factor and
increase it only until you obtain
the desired current. Do not
continue to increase it beyond
where you first note the correct
output current.
3.
Adjust the Z factor for bipolar output.
a.
Press the footswitch pedal and check the voltmeter for a reading
equivalent to 1.10 +0/–.022 A
rms
(1.078 to 1.100 A
rms
).
b.
Stop activation. If the output current was not within the stated range,
adjust the Z factor. Use the Coag Power Control knob for small
adjustments and the cut knob for larger adjustments.
Start with a low value. Adjust until the current is as close as possible to 1.100
A
rms
, but not over 1.100 A
rms
.
Repeat 3a and 3b until the output current is within the stated range.
4.
Disconnect the test cables and remove the 50 ohm resistor.
Checking the Reactance Gain for Monopolar Output
1.
Connect the test equipment for monopolar output.
a.
Connect the test cables to the Monopolar Instrument receptacle.
b.
Connect the 200 ohm resistor to the test cables through the current
transformer.
c.
Connect a monopolar footswitch to the Monopolar Footswitch receptacle
on the rear panel.
Start with a low Z factor and
increase it only until you obtain
the desired current. Do not
continue to increase it beyond
where you first note the correct
output current.
2.
Adjust the Z factor for the pure mode.
a.
Press the Pure button.
b.
Press the footswitch cut pedal and check the voltmeter for a reading
equivalent to 0.949 +0/–.019 A
rms
(0.930 to 0.949 A
rms
).
c.
Stop activation. If the output current was not within the stated range, use
the Cut and Coag Power Control knobs to adjust the Z factor.
Start with a low value. Adjust until the current is as close as possible to 0.949
A
rms
, but not over 0.949 A
rms
.
Repeat 2b and 2c until the output current is within the stated range.
