A at, pin or ball tip is loaded onto a test sample with a precise weight.

The test samples can be of varied shape (such as cylindrical)
as long as there is a at zone of a certain length in the direction of
movement. The length of the track can be adjusted prior to starting
the measurement.

As the test starts, the tip creates a linear wear
track (zigzag pattern also possible). Because of the integrated 16bit
external position encoder, friction can be displayed for any specific
point for each pass.

This is essential to accurately study the trend of friction across the full length of the test.
