Claims

[Scope of Claim for Utility Model Registration] (a) A scale plate with a linear scale and windows formed at multiple locations at equal intervals corresponding to the scale, and (b) A scale plate that moves along the linear scale of the scale plate. to do, by
(c) a servo mechanism that controls the position of the pointer based on the electrical signal of the applied load; and (2) a linear scale on the scale plate behind the scale plate. a long number board which is arranged movably along the direction of movement and displays a plurality of load numbers corresponding to various load ranges to be displayed in each window of the scale board, arranged in the direction of movement; ) A position control device that controls the position of the number plate, and (
f) By switching between various load ranges and using the electric signal of this load range to the above servo mechanism,
By giving position control corresponding to the specified load range to the pointer and sending the load range signal to the position control device of the number board, the specified load can be controlled from among the various load values displayed on the number board. 1. A load measuring device for a material testing machine, comprising: a load range switching operation section for displaying a load number corresponding to the range in each window of the scale plate.
