Bipolar and Monopolar Output RF Leakage Test Procedures
The following procedure is meant to
approximate the test procedure
found in the IEC Standard 601-2-2
Sub-Clause 19.101b). In
applications where you perform the
IEC test, do not use this procedure
as a direct substitute.
Test Setup
1.
Place the Force 2 generator on a wooden table with no exposed metal
on the surface or within one meter of the table surface.
2.
When testing the Force 2-8 PCH generator, use active accessory and
activate it using the footswitch.
Bipolar Procedure
1.
Set Microbipolar to 70 W. Connect a 200 ohm load and the isolated RF
milliammeter between the left
MICROBIPOLAR
receptacle and ground.
2.
Attach a 30 pF capacitor between the right
MICROBIPOLAR
receptacle and
ground.
3.
Activate Microbipolar output and note results.
4.
Repeat process by attaching a meter to the right
MICROBIPOLAR
receptacle, and attaching the 30 pF to the left
MICROBIPOLAR
receptacle.
No reading shall exceed 150 mA.
Use short leads.
Monopolar Procedure
1.
Connect the 200 ohm load and an isolated RF milliammeter between
PATIENT
receptacle and ground.
2.
Attach a 30 pF capacitor between active accessory and ground.
3.
Activate the generator at 5 W in pure cut and note results.
4.
Increase settings at 10 W increments until you reach 35 W. Verify that
no reading exceeds 150 mA.
5.
Increase settings at 20 W increments until you reach 195 W.
Subsequently, increase to maximum output. Verify that no reading
exceeds 150 mA.
6.
Connect the 200 ohm load and an isolated RF milliammeter between
the active accessory and ground.
7.
Attach a 30 pF capacitor between the
PATIENT
receptacle and ground.
Record readings at maximum settings in cut and coag only.
8.
Select the coag mode selected and repeat steps 1 through 5. Increments
of 20 W will continue to 115 W only. Verify that no reading exceeds
150 mA.
9.
If any readings exceeds 150 mA, check the RF leakage calibration
(steps 11 and 12 in the calibration section), and repeat the test.
