A channel is filled with polish to a controlled depth and seated on top of the Adhesive Indexing System. A timer within the Exponent software test sequence is started and an indexable ball probe applies a consistent force to the sample. The probe is then quickly withdrawn and the adhesive force to do this is measured. It can be rotated to allow a clean test site without the requirement to replace or clean and dry the probe between tests.
The channel is pushed to the next site and a set of ten tests are performed in this way with pre-set time delays between the tests.
