Measuring Ground-Wire (Earth) Leakage Current
Note
The Ground-Wire (Earth) Leakage test is available
for AAMI, 60601, and not IEC 62353.
To measure the current flowing in the DUT’s protective
earth circuit, press the softkey labeled Ground Wire
(pending the standard) from the leakage current main
menu. Figure 10 shows the electrical connections between
the Analyzer and the DUT during a Ground-Wire (Earth)
Leakage Current Test.
Within the Ground-Wire Leakage Current test there are a
few combination measurements that can be performed.
Press rocker switches to change polarity or to open or
close the neutral connection.
Note
When changing polarity, Fluke strongly advises
you to perform the action slowly. Allow about
3 seconds to switch from one position to the other.
It is possible to damage the analyzer if you switch
too quickly.
There is no need to open up the test receptacle earth
(ground), since this is done internally during the
measurement.
The following outlet conditions apply when performing this
test:
• Normal Polarity
• Normal Polarity, Open Neutral
• Reversed Polarity
• Reversed Polarity, Open Neutral
