| Abstract: | The mechanical structure and circuits of a new type of automatic zeroing device are designed, which can make the precision of DZW-type gravimeters’ zero conrol reach to 40×10 -8 ms-2 .The design not only accelerates the zeroing operation but also avoids excess and lack of adjustment as well. Moreover, the device can fulfill automatic zero by distant control. |
