HF Leakage Current Test 1
The HF leakage current test number one is an IEC isolated output/bipolar, CF-
type leakage current test. It shows you the amount of open-circuit high
frequency current leakage from a single isolated electrode to earth/ground
through a 200-ohm resistive test load. See Figure 3-3 for a diagram of this test
at the end of this section.
Note
This high frequency leakage current test is intended only for isolated
output electrosurgical units. If you test the active electrode of an
earth-referenced Type BF ESU in the manner described in this
section, you will be measuring the full output of the generator, not a
high frequency leakage current. While conducting this test
inappropriately will not damage the Analyzer, the resulting high
frequency leakage current measurement will not be valid for an
earth/ground referenced ESU.
Test Procedures
The procedures involved with this test include:
• connecting the ESU electrode you want to test to the Analyzer
• selecting a 200-ohm test load resistance
• measuring the ESU’s HF leakage current
• ending the test
To connect the ESU electrode to the Analyzer:
1. If you are testing the ESU’s active or single bipolar electrode, connect the
electrode to the yellow jack active, using one of the test leads from the set,
Part # 1903307, or
If you are testing the ESU’s neutral/dispersive electrode, connect that
electrode to the yellow jack active, using the test lead Part # 2772171.
2. Connect the jumper between the right blue jack dispersive and the left
green jack ground earth reference, using test lead Part # 2772209.
