8
To test electrical equipment for leakage current, it is necessary to use a measurement network that simu-
lates the human body in compliance with applicable standards or laws.
The instrument includes the 8 measurement networks below.
The use of these networks enables instrument compliance with other standards.
Once a measurement network is selected, the instrument displays a leakage current measurement mode
corresponding to the applicable standard or law.
This function makes it possible to continue testing without shutting down the equipment under test when
polarities are changed, which shortens the duration of the test.
(Be sure to use an isolation transformer when using power on polarity switching.)
The instrument provides a rated current of 20 A and a rated voltage of 250 V.
