1 Fit the batteries, see Section 3.1.
2 Turn the crank handle anti-clockwise until
it is fully unwound.
3 Turn the coarse adjustment screw anti-
clockwise until it is fully unwound.
4 Zero the pressure gauge, see Section 5.2.
5 Select the measurement units; MPA
or PSI, see Section 3.3.
5.2 ZEROING THE DIGITAL PRESSURE GAUGE
1 Press to switch the gauge on.
2 Fully unwind the crank handle and coarse adjustment screw
(anti-clockwise) to release all pressure.
3 Press to zero the gauge and set the gauge to store the
maximum force recorded during test, known as ‘Max Hold’.
Max Hold: The display holds the maximum value until the button
is pressed for a second time. ‘Max Hold’ should be switched on before
MAX
undertaking an adhesion test, signified on the display by either MPA
MAX
or PSI. The ‘Max Hold’ feature is switched off when the gauge is
switched off.
Note: “RLOCK” will be displayed if the gauge zero has failed. This is due to the
pressure not being fully released from the instrument. If this occurs,
release all the pressure by turning the crank handle followed by the coarse
adjustment screw anti-clockwise until fully unwound and press to
repeat the gauge zero.
5.3 ATTACHING THE GAUGE TO THE DOLLY
1 Ensure the pin is pushed fully upwards towards the coupling.
2 Pull coupling sleeve up and insert pin into centre of dolly.
3 Release coupling sleeve.
4 The instrument should grip the dolly firmly. If the coupling does not grip the
dolly firmly, there may be excess adhesive in the centre of the dolly. Use
the dolly tool supplied to remove excess adhesive.
4 Turn the coarse adjustment screw clockwise to apply a small
amount of pressure (approximately 1 - 2MPa / 145 - 290psi),
until the coupling firmly grips the dolly.

6 PERFORMING THE TEST
1 Hold the gauge steady with one hand and
turn the crank handle clockwise slowly and
evenly to apply an increasing force to the
dolly and hence stress to the coating.
4 The rate at which the force is applied (the
speed of rotation of the crank handle) should
be in accordance with the relevant Standard.
Continue until either;
(a) the coating fails and the dolly is
removed from the surface
(destructive testing) or;
(b) the minimum specified pressure value is
reached (non-destructive testing).
2 Record the pressure indicated on the display (a) and unwind the
crank handle and coarse adjustment screw.
DO NOT exceed the maximum pressure as overloading could damage the
gauge.
Note: Dollies can be reused after cleaning until either the top of the dolly is
severely deformed or the dolly surface is no longer flat, see Section 8.2
‘Cleaning the Dolly’ on page 7. Additional dollies are available from
Elcometer or your local supplier - see Section 10 ‘Spares & Accessories’
on page 9 for details.

7 ASSESSING THE RESULTS - DESTRUCTIVE TESTING
Once pulled from the surface, examine the bottom of the dolly to
assess the results.
a) Successful Test: In most cases the coating
will fully adhere to the dolly and the test can
be claimed as 100% valid.
b) Partial Failure: In some cases, the coating
will cover only part of the dolly face. A partial
adhesion / coating failure should be recorded
if the coating covers more than 50% of the
dolly face.
Cohesive Failure: When the coating fails in
the body of the coating layer leaving some
coating on the surface and some coating on
the dolly face.
a)
b)

7 ASSESSING THE RESULTS - DESTRUCTIVE TESTING (cont.)
c) Adhesive Failure: If no coating is present on
the dolly this must be recorded as a failure of
the adhesive (or glue). This is normally due to
incorrect or insufficient mixing of the
component parts of the adhesive,
incompatibility of the adhesive and the coating
or the dolly and / or test surface has not been
properly prepared before test - see Section 4
‘Securing the Dolly’ on page 4.
1 Fully unwind the crank handle and coarse adjustment screw
(anti-clockwise) to decrease the pressure to zero.
2 Pull up the quick connect coupling to release the dolly.
3 Press to release the ‘Max Hold’.
4 Press again to zero the gauge and reset ‘Max Hold’.
Note: Failure to release the ‘Max Hold’ and zero the gauge before each adhesion
test will result in an invalid adhesion measure.
8.2 CLEANING THE DOLLY
Cleaning the dolly produces unpleasant fumes - ensure that the
work area is extremely well ventilated. DO NOT inhale the
fumes.
HOT! Exposed very hot surfaces. Use great care when handling
or placing the tongs. Allow to cool before storing.
1 Plug the heating tongs into the mains supply and leave to warm
up for 5 minutes.
2 Heat the dolly with the tongs for 3 to 5 minutes. This will soften
the adhesive.
3 Using a sharp blade, remove the adhesive/coating from the test
surface of the dolly.
4 Drop the dolly into water or allow to cool naturally. Do not put the
heating tongs into water.

fine sandpaper or similar.
6 Use the dolly tool to clear any adhesive from the dolly centre.
7 Wipe the dolly test surface with a solvent to remove oil and
grease.

9 USING A DOLLY PLUG
Particularly in the case of low viscosity adhesives it is advisable to
place a nylon plug in the centre of the dolly before gluing it to the
surface.
This dolly plug stops glue going up the centre of the dolly, which can
impede the pin and prevent the test being carried out properly. Careful
cleaning of the centre hole increases the adhesion values for tests on
a given coating.
Each gauge is supplied complete with five dolly plugs. Additional plugs
are available to purchase separately, see Section 10.4 ‘Dolly Plugs’ on
page 13.
To use the dolly plug:
1 Place the dolly plug through the centre hole on the dolly so that
the tip protrudes just below the test surface.
2 Apply the adhesive to the dolly test surface, see Section 4
‘Securing the Dolly’ on page 4, taking care not to get adhesive on
the plug.
3 Press the dolly and dolly plug onto the sample area for about 10
seconds.
4 Remove the dolly plug from the centre of the dolly and wipe the
end clean using tissue soaked in a suitable solvent. If the dolly
plug becomes stuck to the dolly, use pliers to remove it.
5 Complete the test as described in sections 5 to 6.

10.1 ADHESIVES
The adhesive supplied with the Elcometer 508 is 3M™ Scotch-Weld™
MC1500 Cyanoacrylate Adhesive.
Cyanoacrylate adhesives are normally recommended for gluing dollies
to the sample area due to their relatively quick curing time. However,
there are a number of coatings for which the cyanoacrylate adhesives
may not be suitable. These are:
1 Thermoplastics, celluloses, vinyl, chlorinated rubbers and some
acrylics, due to the possibility of the glue reacting with the coating.
2 Porous coatings e.g. some metal spraying, in which case the
glue, due to its low viscosity will travel into the coating, sticking
particles together and possibly altering its adhesion.
®
A two-pack epoxy such as Araldite or a modified acrylic gel-type
adhesive should be used with the coatings described in (1) and (2)
above.
If in doubt as to the type of adhesive to use, please contact the coating
manufacturer for advice.

accessory, can be downloaded via our website:
www.elcometer.com/images/MSDS/elcometer_mc1500_adhesive.pdf
® ® ®
Note: Other suitable adhesives include Loctite Hysol 907 and Araldite Standard.
The suitability of any adhesive should be determined by the user. Some
coatings can be adversely affected by adhesives. Some adhesives can be
contaminated by coating environments, solvents etc.

10.2 DOLLIES
The Elcometer 508 is supplied with five standard flat dollies with an
outside diameter of 19.4mm (0.76"). Additional dollies are available to
purchase separately together with dollies for measuring on curved
surface - see Section 10.3.
Description Part Number
Standard Flat Dolly, 1 off T9999646-
10.3 DOLLIES FOR CURVED SURFACES
Using a flat dolly on a curved surface can produce misleading results.
The gap between the flat and curved surfaces will not be filled by the
adhesive, resulting in one or more of the following effects:
Ÿ The dolly may peel or twist off instead of being pushed off.
Ÿ The surface area to which pressure is applied, will be modified.
This will lead to results from different curvatures not being
comparable.
Ÿ The amount of adhesive may not be sufficient to withstand the
exerted force, resulting in the adhesive breaking before the
coating separates from the substrate.
These difficulties are overcome by using curved dollies on diameters of
less than approximately 2m (6' 7"). An extensive range of curved
dollies is available.
Curved and flat dollies are all used in the same way, matching the
marks on the dollies with the longitudinal axis on the curved surface.
