Instructions for use for EP4 continuity testers
1. Use
The
EP4
continuity tester is a digital low-impedance measuring device for
reliably measuring cable resistances up to 2000 k
Ω
in electrical installations
with nominal voltages up to 500 V.
It allows to quickly and reliably test large-scale protective conductor, earth-
termination, equipotential bonding and lightning protection systems.
A measuring current of 200 mA and the automatic detection of minimum values
ensure reliable measurement results.
Any measuring cable (up to 3.5
Ω
) can be used to measure resistances between
a reference earth electrode (e.g. equipotential bonding bar) and other measuring
points.
The resistance of the measuring cable is stored during automatic zero balancing
and considered for future measurements.
2. Safety
You have chosen a measuring device that provides a high degree of safety. It
complies with the requirements of EN/IEC 61557-1+4 and EN/IEC 61010.
⇒
To ensure safe and proper use, completely read these instructions for use
before using the
EP4
continuity tester for the first time.
Carefully follow all points included in these instructions for use when
using the
EP4
continuity tester.
The following precautions must be taken:
⇒
Only use the
EP4
continuity tester for power supply systems with a
maximum operating voltage of 500 V.
⇒
Measurements may only be performed on de-energised parts of
an installation.
