Description
Technical field: [0001] The invention relates to the technical field of verification of steel rulers of geometrical length measuring instruments, in particular to a verification device for steel rulers. Background technique: [0002] The steel ruler is a widely used length measuring instrument. The accuracy of the steel ruler will directly affect the measurement accuracy, and according to the "Management Measures of the People's Republic of China for Compulsory Verification of Work Measuring Instruments", the steel ruler used for trade settlement is a compulsory verification Measuring instruments, the research on the steel ruler verification device has important practical significance for the measurement work. Traditional verification devices use microscope readings and manually calculate errors. The labor intensity is high, the verification efficiency is low, the accuracy is not high, and manual calculation errors are prone to occur during data processing, and automatic st...
