13.1 Earth Continuity
Note that measurements can be adversely affected by parallel resistances of additional
circuits or by transient currents.
Connecting a test probe to a hazardous voltage when a point to point measurement is active
will result in that voltage being present on the other tests probes.
This test is applicable to Class I equipment. This test will measure one of the following:
• Resistance between the protective earth terminal in the Equipment Under Test (EUT) mains plug and
the point at which a single test probe is applied – CLI EUT Continuity
• Resistance between two test probes – Point to Point Continuity
• Resistance between the protective earth terminal in an IEC lead mains plug and the protective earth
terminal in the IEC connector – IEC Continuity
To ensure that the connection is satisfactory and of sufficiently low resistance, the measurement will be
displayed in Ohms. There are three possible connection methods for the Earth Continuity test.
CLI EUT Continuity
The test is performed between the red test terminal and the EUT test socket.
Point to Point Continuity
This test is performed between the red test terminal and the black test terminal.
.
IEC Continuity
The test is performed between the EUT test socket and the IEC test socket.
