Position
The position display indicates the indenter's
position relative to the zero position.
Loosen the clamping ring by turning
counterclockwise and remove the zero plate.
5. Carefully pass the prepared test panel
(coated side facing upwards) through the
slot (at 90° to the operator) so that the
center of the indenter is at least 35 mm from
the edge of the test panel.
6. Clamp the test panel in position by turning
the handles on the clamping clockwise –
hand force is suffi cient.
7. There are two test methods. Choose one of
the two procedures below.
Method A – Pass/Fail
A pre-determined depth of deformation is
applied to the test panel in order to test for
compliance to a specifi cation. The test panel
may or may not fail at the applied depth of
deformation. Having set the zero position,
turn both the handles (clockwise as viewed
from the right-hand side of the instrument)
to raise the indenter to the depth required
as shown on the LCD.
Method B – Failure Point
The depth of test panel deformation is
increased until the fi rst moment cracking
and/or detachment of the coating is
observed; this marks the failure point,
and no further deformation is required.
Observe the deformation with standard
corrected vision or, by agreement, with the
Operation
