1. Safety Precautions
Electricity can cause severe injuries, even with
low voltages or currents. Therefore, it is extremely
important that you read the following information
before using your Digital Psc-Loop-Earth Tester and
Electrical Network Analyzer.
1.1 This Instrument must only be used and operated
by a competent trained person and in strict
accordance with the instructions. We will not
accept liability for any damage or injury caused by
misuse or non compliance with instructions and
safety procedures. This instrument inject a High
Current into the Earth.
1.2 This instrument is only intended for Single
Phase operation, 230Vac±20V with the correct
wiring (Phase, Neutral and Earth). It must never
be connected Phase to Phase. Damages could
result. When Conducting a test, do not touch any
exposed metal parts or any conducting parts.
1.3 All RCCB, GFCI and ELCB in the circuit to test
must be bypassed ONLY for the duration of the
test.
1.4 Never open the Tester, except for battery
replacement. ( See Battery replacement section ).

1.5 Before use, always inspect the tester and test
leads for any sign of abnormal condition or
damage. If any abnormal conditions exist (broken
test leads, cracked case, display faulty etc…) do
not attempt to take any measurement or use the
tester. Return it to nearest Distributor for Service.
1.6 The tester has been designed with your safety
in mind. However, no design can completely
protect against incorrect use. Electrical circuits
can be dangerous and/or lethal when a lack
of caution or poor safety practice is used. Use
caution in the presence of voltage above 24V as
these pose a shock hazard.
1.7 Pay attention to cautions and warnings which will
inform you of potentially dangerous procedures.

ZN= Impedance of the Neutral wire from the
transformer, up to the test point. If this
impedance is too high, check the connections
of the Neutral wiring, check the quality of the
line wiring and the switches or contacts in the
Neutral circuit.
ZE= Impedance of the Earth wire, including the
Earth Impedance itself, as seen by the
protection system. Similar checking, specially
at the bounding points should be done is this
path impedance is too high.
