Abstract：5 Burris relative gravimeters were tested by static and dynamic surveying on short calibration line of Lushan and Wuhan gravity datum station, the processed data shows that the observation accuracy of Burris gravimeter is better than 15.0×10 -8 ms -2, the static and dynamic zero drift are very small and present linear, the repeated STD is better than 5.0×10 -8 ms -2.
