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).
