Coating Thickness Range

Applied coats should be cured, thickness tested, visually inspected 
and accepted – before high voltage porosity testing is carried out. 
Coating thickness should be above 150µm; coatings below this 
thickness should be tested with a wet sponge unit.

2.0 OPERATION

Connect the probe and earth leads to the unit. Connect the earth 
clamp to the metallic substrate of the item to be tested – 
substrate should be earthed to ground. Select the probe best 
suited for the test and attach to the probe handle. 
Fit the Fuse (if not already fitted).
Turn the unit on. 
Test the batteries to ensure that they are charged. 
Adjust the voltage control to the required test voltage.
Place the probe near the metal substrate. 
A spark should occur (if not re-check all leads and connections). 
The unit should now be ready for use. 
Re-check the output – adjust if necessary. 
Place the probe on the coated surface and move at 
approximately one metre per four seconds.

A fault is indicated by:

A spark at the probe – this can usually be seen and heard. 
A light flashes on the front panel of the unit. 
An audible sound – buzzer is mounted inside the unit. 

Note

:

A definite flaw should be made in the coating and located with the 

designated test voltage, therefore proving that the unit is locating the 
type of fault you wish to find.   
Probes must be kept in full contact with the surface, gaps in or between 
the probe and the coating may result in flaws going undetected. 
Wire brushes, rubber and coil spring probes should all be kept in good 
condition.
Probes other than fine wire brushes may require higher voltages.

1.0 SAFETY PRECAUTIONS: 

All hand-held high voltage test equipment should be operated 
by responsible, trained and authorised personnel.

The unit must be earthed to both the item under test and to 
ground. 

CAUTION

The Detector output can be up to 65,000 volts. Should the 
operator accidentally make contact with the test electrode, they 
may experience a mild shock or zap, and in order to avoid this 
possibility, the wearing of rubber gloves is recommended.

Furthermore, the operator should enjoy good health and not 
suffer from a cardiac condition. 

If the operator has a 

pacemaker, then they should not use this equipment.

This equipment should only be used for the purpose for which it 
was designed, ie: checking the porosity, or electrical 
breakdown, of dielectric or insulating materials.

It is also recommended that testing should be carried out well 
clear of personnel not involved in the testing procedure, or in 
such a position whereby the surprise of receiving an electric 
shock could cause a related accident, if for example, tests 
being carried out close to moving or rotating machinery, or in 
such an unstable position that the operator could fall and injure 
themselves.

It is recommended that the operator should have an assistant, 
to ensure that unauthorised personnel are kept well clear of the 
testing area, and generally assist when necessary with the 
testing procedure. It is also recommended that the Detector not 
be operated within close proximity of sensitive electronic 
apparatus, such as computer equipment.

DANGER

Do not use the test equipment in any combustible or flammable 
atmosphere, as a test voltage can cause an arc or spark to be 
generated and an explosion could result.

Always consult the plant or safety officer before carrying out a 
test procedure.

When testing tank internals, be certain the tank does not 
contain solvents remaining from the painting procedure.
