INTRODUCTION

Thank you for choosing the PCWI Compact Crest

Meter for testing the voltage output of your PCWI

Compact or other Porosity (Holiday) Detectors.

PCWI have designed this instrument with care, to

provide ongoing efficiency under comprehensive

testing. Under reasonable care in operating, the

unit will provide many years of trouble free operation.

To complement the unit, PCWI maintains a

comprehensive range of test analysis and measuring

instruments for the coatings industry as well as

providing appropriate Certification, traceable to

International Standards.

PCWI, in a continuing desire to achieve the maximum

in corrosion detection competence, welcomes user

enquiries and recommendations.

Yours sincerely

Paul Van Gaal

1.0 SAFETY PRECAUTIONS:

All hand-held high voltage test equipment should be

operated by responsible, trained and authorised

personnel.

CAUTION

During verification with a crest meter, a Porosity Detector

output can be up to 40,000 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 a crest meter to 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.

2.0 OPERATION AND TESTING PROCEDURE

Testing the output of the Detector, and verifying the

voltage on the visual display

Set up Detector for test.

Switch on Detector, and set voltage.

Connect crest meter into system, set the Detector’s voltage

using the crest meter’s display.

Note: The crest meter will measure and indicate peak voltage.
