Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a tiny component measuring device. Background Art

[0002] When measuring tiny components, common measuring tools are often unable to meet the measurement requirements because the components are too small. Using a ruler to measure the size of tiny components below the millimeter level will result in large errors due to the relatively large minimum scale value of the ruler. Even a vernier caliper is not accurate enough for measuring tiny components at the micron level, and more sophisticated instruments are needed. Direct measurement with a micrometer or microscope requires fixed measurement and calibration. For instruments measuring tiny components, calibration requirements are even higher. If improperly calibrated, even high-precision instruments will produce incorrect measurement results. For example, if the zero point calibration of a micrometer is inaccurate, each measurement will have a fixed deviation. Utility Model Content
