Use the wing nut to connect the test electrode to
the high voltage probe (Fig. 1). The metal sweeper
electrode can directly be connected to the high
voltage probe.

Preparing PoroTest® 7 for
operation
1.
Plug the yellow/green earth cable into the two-
pin earth socket of the gauge. Connect one of
the wire ends to the earth clamp or the earth
magnet (for magnetic substrates). Fix the earth
clamp or the earth magnet to an uncoated spot of
the test object (Fig. 5)

2.
Build-up an additional protection earth by securely
connecting the second end of the yellow/green
earth cable to a water pipe, heating installation,
to the earthing contact of a socket-outlet or to
another suitable earthed metal construction. For
in the field testing, the earth rod (available as an
option) should be used.
4.
Use the black high-voltage cable to connect the
high voltage probe to the control unit (4-pin
socket).
5.
Hold the high voltage probe by the metal handle
to prevent static charge.
