Martindale ET4000 / ET4500
leakage current flows to the PE protective conductor or if there is a capacitive
connection between the L and PE conductors.
The low limit prospective short-circuit current value depends on the fuse type,

fuse current rating, fuse trip-out time and impedance scaling factor.
The specified accuracy of the tested parameters is valid only if the mains voltage

is stable during the measurement.
