Page 4: Safety Precautions
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 35,000 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. -
Page 5: Operation
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. -
