1 OVERVIEW

www.elcometer.com en-2

Available in two versions; Manual and Motorised, 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 60mm

(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.

Elcometer 3000 Manual Clemen Unit: The sample is clamped

to a sliding platform which is moved manually.

Elcometer 3000 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.

The Elcometer 3000 Clemen Unit is packed in a plywood and / or heavy duty cardboard and foam

package. It is recommended that this packaging is retained and reused in the event that the

instrument needs to be transported. If the packaging is disposed of, please ensure that this is done in

an environmentally sensitive manner. Consult your local Environmental Authority for further guidance.

1.2 MOTORISED CLEMEN UNIT

3 WORKING SAFELY

To reduce the risk of electric shock, do not open the housing of

the Elcometer 3000 Motorised Clemen Unit. There are no

user-servicable parts inside. The warranty will be invalidated if

the instrument has been opened.

To reduce the risk of fire or electric shock, do not expose the

Elcometer 3000 Motorised Clemen Unit to rain or excess

moisture.

3 WORKING SAFELY (continued)

4.1 INSTALLATION

The Elcometer 3000 Motorised Clemen Unit is heavy; manual

lifting of the tester must be carried out by at least two people.

Place the Elcometer 3000 on a flat level surface suitable for the load

imposed by the tester. The Elcometer 3000 Motorised Clemen Unit

has adjustable feet which can be used to level the tester.

4.2 SWITCHING ON / OFF - MOTORISED CLEMEN UNIT ONLY

Press the On/Off button to switch the unit on. The button will

illuminate when the unit is switched on. Press the On/Off button again

to switch the unit off.

The IEC inlet is protected by one fuse - see Section 10 ‘Technical

Specification’ on page en-10 for fuse rating.

The UK mains plug is fitted with a fuse. When replacing this fuse,

ensure a fuse of the correct rating is used - see Section 10 ‘Technical

Specification’ on page en-10 for details.

Elcometer recommends using mains leads approved by a recognised

testing authority. Examples of suitable mains leads are UK, EUR

H05RN-F 3G 0.75mm 2 cable, US SJT 18AWG/3C cable.

4 GETTING STARTED

5 TESTING A SAMPLE - MANUAL CLEMEN UNIT

Before a sample can be tested, the height of the tool must be adjusted.

5.1 ADJUSTING THE TOOL HEIGHT

1 Place the sample onto the sample platform and fix into position by

rotating the clamp handle.

2 Lift and hold the load beam in its raised position and slide the

sample platform until the centre of the sample is underneath the

tool.

www.elcometer.com en-4

5 TESTING A SAMPLE - MANUAL CLEMEN UNIT (continued)

3 Insert the metal shim (a) between the nylon wheel (b) and the

load beam (c) and then lower the load beam.

4 Adjust the height of the tool (d) until it is touching the surface of

the sample then tighten the knurled wheel (e), turning clockwise,

to lock the tool into position.

5 Raise the load beam, remove the metal shim and slide the

sample platform back to its starting position.

6 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 to 2kg (0 to 4.4lb).

The instrument and sample are now ready for the test to be carried

out.

5.2 TEST PROCEDURE

1 Pull the sample platform towards you in a single smooth action;

the standard speed of movement is approximately 30mm/s

(1.2"/s).

2 The tool will lower down onto the sample at the start of the test

and raise up at the end of the test.

3 Inspect the sample for damage in accordance with the

requirements of the test standard. Repeat the test as necessary,

increase the loading between test.

6 TESTING A SAMPLE - MOTORISED CLEMEN UNIT

Before a sample can be tested, the height of the tool must be adjusted.

6.1 ADJUSTING THE TOOL HEIGHT

1 Connect the unit to the mains power supply and press the Power

On/Off button to switch on the instrument.

2 Place the sample onto the sample platform and fix in position by

rotating the clamp handle.

3 Adjust the height of the tool to its upper position to clear the

sample.

4 With the tool positioned at either end, press the Start button then

immediately press the Power On/Off button. This will stop the

load beam near the centre.

5 Insert the metal shim (a) between the nylon wheel (b) and the

load beam (c) and then lower the load beam.

6 Adjust the height of the tool (d) until it is touching the surface of

the sample then tighten the knurled wheel (e), turning clockwise,

to lock the tool into position.

(d)

(e)

7 Raise the load beam, remove the metal shim and whilst

supporting the load beam, press the Power On/Off button

followed by the Start button to return the tool to its starting

position.

 Supporting the load beam whilst the tool is moving to its starting position

prevents damage to the sample surface, the tool or the sample platform.

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 to 1.5kg (0 to 3.3lb) using the sliding weight.

www.elcometer.com en-6

6 TESTING A SAMPLE - MOTORISED CLEMEN UNIT (continued)

For loads between 1.5 and 5kg (3.3 and 11lb) use the additional 1kg

(2.2lb) supplied. Place the required number of weights on the vertical

rod on the load beam to obtain the correct load. For example, if a load

of 3.5kg (7.7lb) is required, place three of the 1kg (2.2lb) weights on to

the vertical rod and slide the weight to the 0.5kg (1.1lb) mark on the

scale.

The instrument and sample are now ready for the test to be carried

out.

6.2 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,

increase the loading between test.

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 Start button flashes (the electrical detection device operates only

on metallic samples which are uncoated on the reverse side).

6.3 TESTING THICK SAMPLES

The Elcometer 3000 Motorised Clemen Unit as supplied can be used

to test samples with a maximum thickness of 3mm (0.12"). An

Adjustment Kit is available to purchase as an optional accessory which

allows testing of samples up to 20mm (0.8") thick.

The Adjustment Kit consists of the items listed below. Refer to Figure 1

on page en-8 for the location of the parts.
