After the rocker arm H is fixed, the vertical axis K will be perpendicular to it, in order to better read the number of rotation cycles at high or low positions on a sample.
If the user wants to change the test angle (which has been set before leaving the factory), additional weights need to be added. Things like adding washers around the shaft or adding weight to the pivot point on the left side of the rocker to keep the 275g weight on the bottom of the 'O' ring.
new method:
The 275g weight can be reduced without changing the angle and increasing the total amount of the left pivot. Changing the weight of the weight is used to test very specific low-wear products. The need to offset the weight of the weights will result in an increase in the number of test cycles, which will facilitate the judgment of the results of wear.
