Before the sample can be tested, adjust the height of the tool:

1. Place the sample onto the sample platform and fix in 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 (Figure 3).

3. Insert the metal shim between the nylon wheel (1) and the load beam and

then lower the load beam.

4. Adjust the height of the tool (2) until it is touching the surface of the sample

and then tighten the knurled wheel (3) to lock the tool in 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 g to 2000 g

(0 lb to 4.4 lb).
