    • An individual tension meter (1) for measuring tension in a racquet string (9), includes a graspable body (10) and a stress member (2) for stressing the string (9) that are movable relative to each other by pivoting, elastically deformable return elements (3) configured to urge the graspable body (10) and the stress member (2) relative to each other back into a neutral angular position, measurement elements for measuring a magnitude representative of the relative pivoting between the graspable body (10) and the stress member (2), and computation elements for computing the tension of the string as a function of the measured magnitude. The graspable body (10) and the stress member (2) have a first possibility of pivoting relative to each other in a first direction and a second possibility of pivoting relative to each other in a second direction opposite from the first direction.
    • 一种用于测量球拍线(9)中的张力的个人张力计(1)包括可抓握体(10)和应力构件(2),其用于通过枢转地弹性地相对于彼此可移动地应力 可变形的返回元件(3),其构造成将可握持本体(10)和应力构件(2)相对于彼此推回到中性角位置;测量元件,用于测量代表可握体(10) )和应力构件(2)以及用于计算弦的张力作为测量幅度的函数的计算元件。 可抓持体(10)和应力构件(2)具有在第一方向上相对于彼此枢转的第一可能性和在与第一方向相反的第二方向上相对于彼此枢转的第二可能性。
