A test voltage is applied
to the coating by moving a brush probe across the surface and where
there is either a pinhole or flaw, the voltage will spark through the
coating at the flawed location, a red flashing indicator will flash
and an audible alarm will sound. The detected flaw can now be marked
for subsequent repair and testing resumed for the remaining surface
area. If no flaws are detected the test will therefore be
The value of the test
voltage is determined by the dielectric or voltage strength of the
coating thickness. As a rough guide the test voltage can be
approximated between 3 to 5 volts per micron of coating thickness,
therefore 1000 micron would be approx 3kV to 5kV test voltage.

Accurate voltage setting is
achieved by adjusting a 10 ten turn control and the exact test voltage
is displayed on a digital display.
