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)
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.
