The steps to use the Multi-Finger Scratch Tester to study material durability are as follows:

1. Prepare samples: select the material to be tested and prepare it according to the size and shape of the standard sample.

2. Adjust test parameters: Set test parameters, such as load, speed, test time, etc., according to test requirements and material characteristics.

3. Conduct the test: place the sample on the test bench, start the test instrument, and perform the multi-finger scratch test. During the test, the testing instrument will simulate different scratch situations, and record the depth, length, position and other information of each scratch.
