| 摘 要： | 介绍垂直摆倾斜仪自动调零的电路、原理和软件。当摆偏离零位越出记录范围时，仪器将不能正常进行记录。通过单片机、模拟开关及精密电阻网络进行自动调零，自动调零电路能自动产生一个精确的补偿电压，使仪器的输出自动调整到零位附近。

| Abstract: | The principle and software of the auto zero point adjustment circuit in VS tiltmeter are described. The zero position of instrument is adjusted automatically by using the single chip micro processor, analog switch and precise resistance net. While the tiltmeter can not record normally because the pendulum deviates from the zero point, the auto zero point adjustment circuit can produce a precise compensation voltage to adjust the pendulum to the zero position. |

| Keywords: | tiltmeter auto zero point adjustment compensation voltage |
