ActiveDesign and metrological characteristics of dial test indicators（lever type）
杠杆指示表的设计和计量特性
Application Summary AI generated
This standard specifies the design and metrological characteristics for lever-type dial test indicators, including dimensions, graduation values, measuring force, and permissible errors. It is applied in manufacturing and quality assurance contexts where precise comparative measurements of geometric deviations, such as runout, flatness, or alignment, are required on machined parts. The standard ensures consistency and accuracy for these instruments used in workshops, inspection labs, and calibration facilities.
