1 ABOUT YOUR TESTER
The Elcometer 3000 Clemen Unit is a robust and simple-to-use instrument for
evaluation of the resistance to scratching of a coated surface. The sample can
be metal, wood, glass, plastic or other hard materials.
A tool fitted with a hemispherical ball is lowered gradually onto the surface of
the sample and moved in a straight line a distance of 60 mm (2.4"). The
downward force exerted by the tool onto the surface is adjustable by means of
a sliding weight.
Depending on the purpose of the test and the force applied, varying degrees of
penetration of the tool into the coating are observed, from a superficial trace to
total destruction.
The Elcometer 3000 is available in two versions; the original Manual Clemen
Unit and the Motorised Clemen Unit.
•Elcometer 3000/1 Manual Clemen Unit. The sample is clamped to a sliding
platform which is moved manually.
•Elcometer 3000/3 Motorised Clemen Unit. The sample is clamped to a fixed
platform. At the press of a button, the tool is moved across the sample and
stops automatically at the end of its travel. Contact between the tool and a
metallic sample is indicated by a lamp and voltmeter.
1.1 Standards

8. Slide the weight along the load beam to the required load and lock in place
by tightening the knurled wheel. The load can be set from 0 g to 1500 g
using the sliding weight.
For loads between 1500 g
and 5000 g (3.3 lb and
11 lb), use the additional
1000 g weights supplied
with your instrument; place
the required number of
these weights on the
vertical rod on the load
beam to obtain the correct
load. For example, if a load
of 3500 g (7.7 lb) is
required, place 3 of the
1000 g weights on the
vertical rod and slide the
weight to the 500 g mark on
the scale.
The instrument and sample
are now ready for the test to
be carried out (Figure 6).
4.2 Test procedure
Keep fingers clear of the mechanism
during use.
1. Press the Start button.
The tool will start to move and will lower
down onto the sample at the start of the test,
raise up at the end of the test and then stop
automatically.
2. Inspect the sample for damage in
accordance with the requirements of the test
standard. Repeat the test as necessary, increasing the loading between
tests.
The complete destruction of a paint film on a metallic sample is observed when
the voltmeter needle indicates 10 V to 12 V and when the light in the start button
flashes (the electrical detection device operates only on metallic samples which
are uncoated on the reverse side).

6 TOOL ACCESSORIES
Due to the nature of the test, the ball tool will wear with use. It is advisable
therefore to keep a spare tool in stock - see “Spares” on page 15 for ordering
information.
In addition to the standard 1 mm (0.04") ball tool, a number of other tools are
available:
6.1 Cutting tool - for scratch testing
The optional cutting tool gives a much more aggressive scratch than the
standard ball tool. When using a cutting tool, follow the same adjustment and
test procedure as given for the standard ball tool.
6.2 Rubber tool - for drying time assessment
The optional 1 cm² rubber tool is used for drying time assessment.
Typical drying time test procedure
Set the load to 100 g. Clamp the test sample
a
onto the platform and then place
a sheet of cigarette paper, or textile fibres, cotton wool, etc. on top of the
sample. Place the rubber tool carefully onto the paper.
After one minute, lift up the tool, remove the test panel and turn it upside down
so that the painted side is facing down. If the paper remains stuck, the paint is
not yet dry.
7 MAINTENANCE
The Elcometer 3000 Clemen Unit is designed to give many years reliable
service under normal operating and storage conditions.
The tester does not contain any user-serviceable components. In the unlikely
event of a fault, the Elcometer 3000 should be returned to your local Elcometer
supplier or directly to Elcometer. The warranty will be invalidated if the
