STEP 6: Place the electrode sponge on the coated surface and begin
passing the sponge across the surface (See Diagram 2 Below). Several
passes should be made over the test area to ensure that moisture has
penetrated any possible holiday. If the sponge passes across a pinhole
in the coated surface an audible horn from the detector will begin to
sound and the red light on the control panel will light up. The audible
and visual alert will stop once the electrode moves away from the
pinhole. For more precisely locating the holiday use the corner of the
sponge in the area the holiday occurred.
IMPORTANT! Care should be made to ensure that the sponge
stays as clean as possible. Dirt or other contamination of the test
surface adds resistance, which impedes the current flow capability of
the sponge. This can result in missing holidays in the test piece.

Test Buttons
Push the 80k test button,
the horn should sound.
Push the 100k test button,
the horn WILL NOT sound.
Detection Testing
Touch electrode/wand
directly to bare ground
cable to test that the unit is
functioning properly.
The horn will sound and the
light on the control panel
will light up.
If the detector does not
detect then ensure ground
cable and electrode wand
are correctly connected.
If the detector still fails
to detect a defect in the
coating a repair may be
needed, contact Pipeline
Inspection Company for
support.
