1). Select a 100mm×100mm×50mm test piece from the same batch of samples. If the thickness is not enough, it can be stacked, but it cannot be bonded together with adhesive.

2). Place the equipment on the horizontal platform, pad the feet, use a level, adjust the four feet to adjust the equipment table to the level.

3). Place the sample flat on the test platform

5). The user can choose “500MM (ASTM)” and “460MM (GB/EN)” in the drop height. If you select “500MM(ASTM)”, the “height” of the display will change to 500mm, and the user needs to raise the plexiglass tube to the position of 500 mm. On the contrary, you need to lower the plexiglass tube to the position of 460mm.

6). After the setting is completed, press the “Clear All” button to clear the test results. “Error setting” can be set according to the needs, as shown in the figure below
