PAN Xue, GAO Guo-wei, WANG Chao, et al. Design and realization of electronic gradienter of dispeling zero shift automatically[J]. 2008, (1): 79-81+84. DOI: 10.13873/j.1000-97872008.01.031.
Change of time and temperature will bring zero shift to electronic gradienter nowadays.Manual regulation is necessary.An intelligence electronic gradienter is presented which can automatically dispel the zero shift.Its design concept is based on the ancient method that the level can find horizon by revolving 180°.The hardware design
software design and experiment analysis are introduced.The experimental result indicates that the method can largely improve the measuring accuracy of the gradienter.
