Hf Leakage Current Test 3; Hf Leakage Current Test 2 - Fluke RF303 Operator's Manual

HF Leakage Current Test 2

The HF leakage test number two is an IEC earth-referenced, BF-type leakage
current test. You perform the test by connecting a 200-ohm resistive test load
from the ESU's active electrode to earth/ground on the Analyzer. High
frequency leakage current is then measured through a second 200-ohm
resistive load. You can view the resulting measurement on the Analyzer's
display. See Figure 3-4 for a diagram of this test at the end of this section.
Test Procedures
The procedures involved with this test include:
connecting the ESU 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 to the Analyzer:
1. Connect the ESU Active electrode to the right gray jack aux HF leakage,
using one of the test leads from the set, Part # 1903307.
2. Connect the ESU Neutral/Dispersive electrode to the left blue jack
dispersive, using test lead Part # 2772171.
3. Connect a jumper between the yellow jack active and the left green jack
ground earth reference, using test lead Part # 2772209.
4. Connect a jumper between the right blue jack dispersive and the left gray
jack aux HF leakage, using test lead Part # 2772209.
5. If operating under battery power, attach a test lead from the set (Part #
1903307) from the battery ground on the side panel to the ground earth
reference.
To select a 200-ohm test load resistance setting:
1. Press the OHMS SELECT increase (+) or decrease (-) buttons repeatedly
until the test load value 200 appears in the display. After approximately
one second, the display returns to a blank screen. Below is an example of
a test load value as it appears in the display.
