FIELD: measurement engineering.
SUBSTANCE: electronic twisted-spring micrometer can be used for measuring linear sizes. Internal partition is mounted additionally in case of device which partition forms face and rear cavities inside the case; the cavities are disposed at face and rear caps. Plate for data processing is disposed in face cavity onto internal partition. Display, "switch on" and "switch off" functional buttons, and button combining performance of bringing-to-zero functions and range changing functions are disposed onto the plate. Protecting transparent window is mounted onto face cap in front of display. Film panel provided with transparent window is disposed onto face cap as well which window is brought into contact with protecting transparent window and with film keyboard.
EFFECT: improved reliability.
