The paper inctroduces the guide for the design of a portable instrument for straightness measurement of large machine tool. the measuring instrument is designed with two-quadrant photocell which is used as the position sensor, single-chip for the processor is MSP430F427 which have LCD driver circuit, the instrument is charged by lithium battery-powered. Its size is small, no external connection when it is used, data acquisition, processing and error displayed can be done in the part of light target. It have the advantage of convenience, simple and high measurement accuracy when it is used.
