For example, when a
PosiTest LPD
operator prepares to test for
coating pinholes on a steel beam he/she first connects the ground
clamp and 4.5 m (15’) ground wire to an uncoated area of the beam.
When the detector is powered-up,
GroundSense
causes the LED
for the selected voltage to blink until the operator couples the wet
sponge by placing it on the coated beam. When the wet sponge is
lifted from the coated beam,
GroundSense
causes the LED for the
selected voltage to blink. The LED will also blink if the ground clamp
is accidentally removed from the beam while the wet sponge is in
contact with the beam.
If the 12 m (40’) ground wire is laid near a conductive (i.e.
concrete or metal), grounded surface during testing, it may cause
GroundSense
to falsely indicate a coupled condition after the wet
sponge is removed from the coated part. If
GroundSense
indicates
a coupled condition before the operator contacts the wet sponge to
the coated surface, its indications should be ignored.
GroundSense
is for advisory use only, and does not replace the operator’s
responsibility to ensure that the detector is properly grounded.
