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
