VERIFYING PERFORMANCE PROCEDURES
In addition to the operational checkout, performance of the apparatus must be
verified by authorized personnel semi-annually. You use a radio frequency (RF) watt (w)
meter capable of a 30w reading and 500 ohms load (electrosurgical tester) for testing.
a. Verify the BIPOLAR Output Power.
(1)
Set the RF watt meter to a 500 ohm load.
(2)
Attach the hand piece to the RF watt meter.
(3)
Plug the hand piece into the BIPOLAR outlet.
(4)
Turn on the hyfrecator and the RF watt meter.
(5)
Adjust the control dial to maximum current intensity.
(6) Verify that the RF watt meter reads 30 + 2 watts and that both BIPOLAR
outlets are of equal power.
(7)
Turn off both units.
(8) If the output is correct, go on to verify the HIGH output power (see
paragraph 1-8b). If the output is incorrect, calibrate (see paragraph 1-9).
b. Verify the HIGH Output Power.
(1)
Set the RF watt meter to a 500 ohm load.
(2)
Attach the hand piece to the RF watt meter.
(3)
Plug the hand piece into the HIGH outlet.
(4)
Turn on the hyfrecator and the RF watt meter.
(5)
Adjust the control dial to maximum current intensity.
(6)
Verify that the RF watt meter reads 18 to 28 watts.
(7)
Turn off both units.
(8) If the output is correct, go on to verify the LOW output power (see
paragraph 1-8c). If the output is incorrect, calibrate (see paragraph 1-9).
