Springiness is a measure of how far the sample returns after being compressed to the target
deformation.
Adhesiveness is a measure of stickiness and is calculated as the area under the negative peak as
probe withdraws after the first compression.
TENSION TEST
– this test can be used to pull apart a sample, usually using grip fixtures to apply
tension load on the sample.
The operator sets the trigger value, target deformation and the test speed using the Tension menu
screen:
TEST: TENSION
TRIGGER: XXX.X g
DEFORMATION:XXX.X mm
SPEED: XX.X mm/s
III.21
After pressing Start the operator is presented with this reminder screen:
*ATTACH TENSION
FIXTURES
*PRESS START

Be sure grips or other sample fixtures are secure and aligned then press START. The Scroll/Select
knob now becomes a tool for adjusting the position of the grips so that the sample can be clamped.
Rotate knob to move 1mm/click or hold knob down to descend at 4.5mm/s:
*ADJUST POSITION
USING SCROLL/SELECT
*PRESS START
DEFORMATION:XXX.X mm

The deformation value shown in this screen is the current distance from the top Home position and
as such shows how much travel is possible once the test begins. Be sure this value is greater than
the sum of the distance necessary to reach the trigger plus the programmed target deformation.
When clamping the sample try to exert only minimal lateral loads on the probe shaft. Pressing Start
as shown below will start the test:
*CLAMP SAMPLE
*PRESS START
