7. Activate the Mega Power using the footswitch on monopolar A. Verify and
an audible tone while the ESU is activated.
8. Activate the Mega Power and Verify the output power is 20 Watts +/- 4
watts using the ESU analyzer.
9. Change the power setting on the Mega Power to 120 watts, activate the
Mega Power and Verify the output power is 120 Watts +/- 24 watts using
the ESU analyzer.
10. Disconnect the Mega Power monopolar A from the ESU analyzer and
connect the Bipolar output to the ESU analyzer.
11. Set the Mega Power Bipolar to 10 watts, and set the ESU analyzer to 100
ohms.
11. Activate the Mega Power using the bipolar footswitch. Verify and an
audible tone while the ESU is activated.
12. Activate the Mega Power and Verify the output power is 10 Watts +/- 2
watts using the ESU analyzer.
13. Change the power setting on the Mega Power to 80 watts, activate the
Mega Power and Verify the output power is 80 Watts +/- 16 watts using
the ESU analyzer.
14. Both footswitch monopolar A & B, and hand activation monopolar A & B
should be tested.
Contact Quality Monitoring (CQM) Test.
This test requires test leads to connect to the CQM receptacle, fixed load
resistors and a variable load resistor.
15. Turn on the Mega Power ESU, the alarm should be red.
16. Attach a 50 ohm load across the two wires of the test lead. Plug the CQM
Test lead into the Patient Return Receptacle. The alarm light should turn
green.
17. Unplug the CQM Test lead from the ESU, the alarm should sound and the
light should turn red.
18. Attach a 150 ohm load across the two wires of the test lead. Plug the CQM
Test lead into the Patient Return Receptacle. The alarm light should
remain red.
19. Unplug the CQM Test lead from the ESU.
20. Attach a variable resistor set at 50 ohms across the two wires of the CQM
test lead. Plug the CQM Test lead into the Patient Return Receptacle. The
light should turn green.
