III.7 Running A Test
A test is initiated by depressing the start button. The operator is reminded to attach a probe, then
press start again to zero the weight of the probe and begin the test.
* ATTACH PROBE *
PRESS START
TO CONTINUE
Figure III.4
Depressing the Select/Scroll knob at any time during the test, or even while test results are displayed,
will show the current test parameters. At the completion of the test, the final results will be displayed
until the start button or reset button is pressed. The reset button will return the instrument to the
default display where the test mode may be selected. The start button will begin the same test again.
A test may be repeated simply by depressing the start button while viewing test results.
The test may be stopped at any time by using the stop/reset button or by pressing the emergency
stop button. We recommend that the stop/reset button be used for normal operation. The emergency
top is intended for emergency use only.
It may happen that the instrument overloads during a test. This will happen if the load exceeds
120% of the load cell capacity. When an overload condition occurs the display will show the
following:
TEST TERMINATED
MAXIMUM LOAD REACHED
PRESS RESET FOR MENU
Figure III.5
Depressing the reset button will return to the test mode menu. Correct the reason for the overload
and retest.
NORMAL TEST
– performs a single compression of the sample then immediately returns
to HOME starting position.
The operator sets the trigger value, target deformation (travel distance into the sample) and the test
speed using the Normal menu screen:
TEST: NORMAL
TRIGGER: XXX.X g
DEFORMATION:XXX.X
mm
SPEED: X.XX mm /s
Figure III.6
A normal test performs a single compression cycle when the operator depresses the start button.
Beginning at the position where the trigger load is measured, the probe descends at the programmed
test speed to the target deformation, then returns immediately to home/starting position. Return
