The LSE value can help to judge the softness (formability) of the sample wire according to the wire size. A larger LSE value indicates that the prototype has a larger formability, and has a better ability to withstand bending and twisting in the winding process of motor and coil. Low LSE values (for the same wire size) indicate that the wires are relatively rigid and have greater elasticity. High precision digital electronic measuring and pressure measuring elements are used to measure tension and tension. The pressure measuring element has built-in safety overload function. The special sample clip is simple and convenient to use.
