3.3 Checking the correctness of PE (protective earth) connections
When the meter is connected as in the drawing, touch the contact electrode and wait for
about 1 second. If voltage is detected on the PE conductor, the device:
will display text (installation error, the PE lead connected to the phase conductor) and
will generate a continuous audio signal
This option is available for all measuring functions that apply to residual current devices (RCD) and
fault loop except Z
L-N
measurement.
WARNING
When phase voltage is detected on PE lead, measurements must be immediate-
ly stopped and a fault in the installation must be removed.
Make sure to stand on non-insulated ground when measuring. Insulated ground
may cause an incorrect test result.
If the voltage on the PE conductor exceeds the acceptable limit value (approx 50 V),
the meter will signal the fact.
If the IT network has been selected in section 2.2.1 step , the contact electrode
is inactive.
