Note: The described features should be in line with Table 1: Test Parameters.
Note1: The Repeatability refers to the repeatability within the test range.
Test Principle
The pre-conditioned specimen is placed on a flat test plane, the pressure foot which is paralleled to the test plane will drop down on the upper surface of the specimen with certain pressure applied on. The displacement sensor with the pressure foot will detect the space between the upper and lower surface of the specimen, which is the thickness of the specimen.
