FIELD: measuring engineering. ^ SUBSTANCE: meter comprises flat housing provided with flat handle and holder for movable members. The holder is secured to the housing. The movable members are freely mounted in the holder and project over the holder by a distance equal or less than that between the bottom end of the movable member and the housing. The length of the groove made in the middle of the handle from the side of scale is larger than the stroke of the stop. The narrow part of the stop is secured to T-shaped core, which can freely move inside the handle. The bottom end of the core receives the first end of the spring, which permanently presses it to the housing bottom. The second end of the spring is secured to the handle bottom. ^ EFFECT: expanded functional capabilities. ^ 4 dwg |
