摘  要:
A portable digit display micrometer with large-scale integrated circuit and LCD in cir-cuit design has been developed. It has much smaller size and lower power consumptionthan an inductance micrometer. Its advantages help the type of micrometer to be used wide-ly in many fields. The principle, circuit design and technical index of the micrometer are presented.
