摘要
分析高精度倾斜仪零点漂移的几大诱因,并将遥控调零和自动调零电路运用于垂直摆倾斜仪,解决了倾斜仪调零难、精度低的问题,调零精度达到200 mV(仪器量程为2000 mV)。
The major incentives of zero-drift of high-precision tiltmeter are analyzed and two kinds of zeroing methods：remotely zeroing and automatically zero of high-precision tiltmeter are introduced.The two circuits for remotely zeroing and automatically zeroing are applied in vertical pendulum tiltmeter to solve the zeroing problems.So the zeroing accuracy reaches 200mV（the range of the instrument is 2000mV）.
