Earth continuity resistance

10.1.12
This test ensures that the connections between the protective conductor terminal in the
mains plug of the device under test and earthed accessible conductive parts of the device
under test are satisfactory and of sufficiently low resistance. This test has to be performed
on Class I (earthed) appliances. The instrument measures the resistance between:
 Mains test socket's PE terminal and the S/EB1 terminal.
