4. Operation
1. Rotate the handles [3] clockwise (as viewed
from the right-hand side of the instrument)
to lower the hemispherical indenter just
below the level of the bottom clamping ring
[2].
2. Switch on by pressing the operating button
[4]. The LCD [5] will show - - - -, followed by
its current position or ZEr0 (if below the zero
datum position). Switch on the magnifier
light [7], if required. Note that ZEr0 will
flash if the indenter is lowered about 0.5mm
below the zero datum position.
3. Insert the zero plate and rotate the handles
on the clamping ring clockwise to securely
retain the plate.
4. Lightly hold one of the operating handles
with two fingers and slowly turn the
handle anticlockwise (as viewed from the
right-hand side of the instrument) to raise
the hemispherical indenter until a slight
resistance is encountered. When this position
is reached, stop turning; the Indenter will
now be in contact with the underside of the
substrate. Briefly press the button [4] to zero
the instrument’s measurement system (datum
position)1. The LCD will show 0.00. Remove
the zero plate.
5. Carefully pass the prepared substrate (coated
side facing upwards) through the slot (at 90°
to the operator) so that the central axis of
the substrate is at least 35 mm from the edge
of the substrate
