Primary Function of the Testing Machine
 

1. Can measure the average, maximum, and minimum tangential friction force of a writing pen rotating once on A4 paper, and plot the curve in a load-time coordinate system.

2. Features a paper feeding mechanism: automatic paper feeding.

3. The diameter of the circular marking can be adjusted, and the line speed of the marking can be continuously fine-tuned to any desired setting.

4. Writing Pressure: Weights can be placed on the pen holder for underlining, which can be used individually or in combination.

5. Standardize the test program through a computer, input test parameters to establish a plan, then click 'Test' for automatic completion.

6. The same pen core can be used for one test or consecutive tests up to ten times; the average of the tests is taken. It's also possible to pre-draw a certain number of circles before measuring, with the number of circles adjustable.

7. During the circular process, a real-time force-time curve can be plotted, and the test curve features storage capability.

8. Clamping Method: Angle adjustable, 60-90° range.
