基于LabVIEW的高阻自动测量系统

超高阻测量电路中,很小的寄生电容也会带来很大的电路时间常数,等待电路稳定会耗费测量者很长的时间,人为带来的噪声也会使测量的准确性降低。基于改进型的惠斯登电桥原理,运用LabVIEW面向组件技术设计实现了高阻自动测量系统实现精密的高阻测量。主要讨论了高阻自动测量系统软件的状态机设计、组件的可重用性和错误处理机制实现。运用该自动测量系统,能够实现无人无干扰的自动测量,满足高阻精确测量的需要。

Automatic measurement system for super high resistance based on LabVIEW

In circuit of super high resistance measurement, very small parasitic capacitance can bring in high value of time constant.Manual measurement costs much time to wait for the circuit stability,and the noise also reduces the accuracy.In this paper,using an improved Wheatstone bridge, an automatic measurement system for super high resistance was developed based on LabVIEW Component Oriented Design technique.The paper discussed the design of state machines, the reusability considerations and the error handling ...
