elcometer 3000 Motorised and Manual Clemen Unit

OVERVIEW

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.

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.

The I EC 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-1 O 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.

GETTING STARTED

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.

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.

TESTING A SAMPLE – MANUAL CLEMEN UNIT

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

ADJUSTING THE TOOL HEIGHT

Place the sample onto the sample platform and fix into position by rotating the clamp handle.
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.
Insert the metal shim (a) between the nylon wheel (b) and the load beam (c) and then lower the load beam.
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.
Raise the load beam, remove the metal shim and slide the sample platform back to its starting position.
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 O to 2kg (0 to 4.4Ib ).

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

TEST PROCEDURE

Pull the sample platform towards you in a single smooth action; the standard speed of movement is approximately 30mm/s (1.2″/s).
The tool will lower down onto the sample at the start of the test and raise up at the end of the test.
Inspect the sample for damage in accordance with the requirements of the test standard. Repeat the test as necessary, increase the loading between test.

TESTING A SAMPLE – MOTORISED CLEMEN UNIT

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

ADJUSTING THE TOOL HEIGHT

Connect the unit to the mains power supply and press the Power On/Off button to switch on the instrument.
Place the sample onto the sample platform and fix in position by rotating the clamp handle.
Adjust the height of the tool to its upper position to clear the sample.
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.
Insert the metal shim (a) between the nylon wheel (b) and the load beam (c) and then lower the load beam.
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.
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.
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 O to 1.5kg (0 to 3.3Ib) using the sliding weight.

For loads between 1.5 and 5kg (3.3 and 11 lb) use the additional 1 kg (2.2Ib) 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 (7.7Ib) is required, place three of the 1 kg (2.2Ib) weights on to the vertical rod and slide the weight to the 0.5kg (1.1 lb) mark on the scale.

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

TEST PROCEDURE

Keep fingers clear of the mechanism during use.

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.
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).

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.
