1. Safety Rules
CAUTION RISK OF ELECTRIC
SHOCK
This 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 lack of caution or poor
safety practices are used.
Do not carry out field measurements on either the
power system grounding, during periods of forecast
lightning activity, in areas that encompass the station
being measured or of the power network connected
to the station being measured. In the event that
lightning occurs, stop all testing and isolate any
temporarily installed test spikes.
Preparations for testing of power system grounding
can leave personnel vulnerable to exposure caused
by faults at or fed from the system under test,
transferred potentials from remote test grounds, and
inadvertent line energisations.
While the probability of the occurrence of one of these
events is low, personnel safety will, nevertheless, be
enhanced by the following:
When working near high tension systems, rubber
gloves and shoes should be worn.
Work on clean, dry crushed rock or an insulating
blanket.
Avoid bare hand to hand contact between the tester
and extended test leads.
