Valleylab Force FX-C - Check the Output for the Cut Modes

Force FXTM-C Service Manual
Periodic Safetv Check
Checking the Monopo/ar Output
Step 1 - Check the Output for the Cut Modes
A. Verify that the generator successfully completes the self-test as
described in 'H'Stin;;: the Generator in this section.
B. Connect the test equipment for monopolar output.
(1) C01U1ect one test cable to the left jack in the Monopolar 1 jCEM
Instrument receptacle. Pass the test cable through the current
transformer and connect the current transformer to the voltmeter.
(2) Use a test cable to short the two pins on the Patient Return
Electrode receptacle.
(3) Connect the second test cable from the voltmeter to both pins of the
Patient Return Electrode receptacle.
(4) Connect the 300 ohm resistor across the output jacks at the end of
the test cables.
(5) Connect the monopolar footswitch to the Monopol1.r 1 Footswitch
receptacle on the rear panel of the generator.
G. Press the Pure button.
D. Press the Cut up (~) or down ( v ) arrmv buttons to set the cut power
to 80 >vatts.
E. Test the monopolar cut output.
(1) Press the footswitch cut pedal and, while activating the generator,
note the output on the voltmeter.
(2) Release the foots witch pedaL
(3) Based on the voltmeter setting and the current transformer you are
using, calculate and record the output current.
F. Press the Low cut button and repeat step I.E.
G. Press the Blend button and repeat step 1.E.
H. Verify that the generator output for each mode is 516 37 rnA rms.
If the output is outside the specified range, calibrate the monopolar
output as described in calibration steps 5, 6, 7, and 8. Then repeat this
procedure. If the output for one or more cut modes remains outside the
specified range, call the Valleylab Service Center.
