Error -200279 occurred at DAQmx Read (Analog 1D Wfm NChan NSamp).vi:2 Possible reason(s): Measurements: Attempted to read samples that are no longer available. The requested sample was previously available, but has since been overwritten. Increasing the buffer size, reading the data more frequently, or specifying a fixed number of samples to read instead of reading all available samples might correct the problem.

大概意思就是，采集太快，读取太慢，缓冲区容量不够，溢出。

解决方法就是更频繁的读取数据或修改采样值。
