BioTester Tip: Ideal Specimen Size
The BioTester is designed for small specimen sizes. For Standard BioRakes (5 tines
spaced at 1 mm) the ideal specimen size is square with side lengths of 5.5 - 6 mm. If a
specimen is not in the ideal range, it may still be mounted, but the placement of the rake
tips will need to be adjusted. Also, BioRakes of different size are available and may be
used.
Manual adjustment of rake positions during specimen loading may be necessary to
ensure that the rakes puncture the sample correctly.
These manual adjustments result in a change in specimen size, which in turn results in
a change in actuator displacement profiles. The specified specimen size is displayed at
the top of the screen while the current specimen size is displayed on the left of the
screen just below the force output.
At any point before the test has started, specimen size can be changed using one of the
following methods:
•
Press
Specified Size
•
Use the Actuator Control jog button arrows.

Step 7: Execute the Test

Select Execute from the File menu, or press the

Step 8: Terminate the Test Prematurely (optional)

You can stop a test at any time by clicking
menu. This is preferred over powering down the equipment, as it allows the software to store the
current actuator position.
At the end of the completed test (both normally or prematurely terminated) the actuators will
maintain their current position.
BioTester Tip: Specimen Thickness
Measuring the specimen thickness before and/or after a test is performed will allow
stress calculations to be made from your output data.
