| Abstract: | 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). |
| Keywords: | high precision titlmeter zero drift remotely zeroing automatically zeroing vertical pendulum tiltmeter |
