The PE test is executed in the so-called 4-
wire technique. This is necessary, in order to
determine the resistance exactly without
being influenced by the measure leads.
At the 4-wire technique, the test is executed
via 4 leads. Two leads are necessary for
supplying the test current and 2 leads are
necessary for measuring the voltage drop at
the PE.
The test current can be a direct current or an
alternating current. At Schleich testers the
test current is an alternating current, which
is generated in a constant-current source.
It is required by standards that the no-load
voltage is max. 6V or 12V.
