Figure 6. Typical Built-Up Roof on metal deck.
Apart from the replacement of the 9V PP3 alkaline batter-
ies, the only maintenance check required is the regular
examination of the electrode mat. Clean with a damp cloth
and soapy solution, but never use solvent to clean the
surface. If damage is identified, the mat should be replaced.
In the event of instrument malfunction, return the instru-
ment immediately to your supplier.
The Tramex Dec Scanner and RWS Roof and Wall Scanner
are not suitable for use on any roofing with electrically
conductive or metal-faced membranes. Metal and other
electrically conductive surface coverings and near-surface
embedded metallic components are not suitable for
surveying with these instruments because of the electrical
conductivity of these materials. Most types of black EPDM
produce false positive readings when tested with this
method due to the material’s high dielectric constant. The
degree to which these false positives need to be factored
out will affect the depth of signal penetration. Aluminum foil
on top-faced insulation or waterproofing membranes give
false positive readings, however liquid-applied aluminum
pigmented emulsified asphalt based coatings do not
normally have a significant effect on the readings.
Requirements for quality management and validation
procedures, such as ISO 9001, have increased the need for
regulation and verification of measuring and test instru-
ments. It is therefore recommended that calibration of the
Dec Scanner should be checked and certified in accordance
with the standards and/or protocols laid down by your
industry (usually on an annual basis) by an authorized test
provider. The name of your nearest test provider and
estimate of cost is available on request. Calibration adjust-
ments should not be carried out by anyone other than
Tramex or their authorized service provider who will issue a
calibration certificate on completion.

tion for any special, indirect, or consequential loss or

tion, loss of business, revenue, profits, data, savings or
goodwill), whether occasioned by the act, breach, omission,
default, or negligence of Tramex Ltd., whether or not

indemnity. Without prejudice to the above, all other warran-
ties, representations and conditions whether made orally or
implied by circumstances, custom, contract, equity, statute
