4.2 Measurement set-up

Any measuring cable (up to 3.5 Ω) can be used between the reference earth elec-
trode (e.g. equipotential bonding bar or system earth electrode) and the EP4 con-
tinuity tester. This measuring cable is calibrated according to section 4.3.
The EP4 continuity tester reaches measuring points that are more than 100
m away from the reference earth electrode. To avoid inductive interference,
the cable should be completely uncoiled in surroundings with strong field
effects.
⇒ Clamp the measuring cable to the reference earth electrode with good
electrical contact (remove corrosion, if required)
⇒ Plug the free end of the measuring cable into the socket of the EP4
continuity tester.
When using an uncoiler, plug the 1 m measuring cable supplied into the
socket of the uncoiler.
