How Can I Perform a Self-Test of My NI-DAQmx Device Programatically in LabVIEW? I want to programatically perform an NI-DAQmx Self-Test in LabVIEW, similar to that available in Measurement and Automation Explorer, but I can't find the corresponding VI. Where can I find this VI or how should I implement a self-test in my program? URL: http://digital.ni.com/public.nsf/allkb/4927D77E27D907CF8625741F006C987B

如何在LabVIEW裡用程式的方法對NI-DAQmx的裝置進行Self-Test? 我希望在在LabVIEW裡用程式的方法對NI-DAQmx的裝置進行Self-Test, 就像我們在Measurement and Automation底下做的一樣。但是我找不到對應的VI。請問我要在哪裡才可以找到這個VI?或是我應該怎樣在我的程式裡執行self-test? URL: http://digital.ni.com/public.nsf/allkb/0D7A321CAC2E4B658625742500231A4D

Acquiring On-Board Temperature from a PCI-6704 Static Analog Output Module How can I read the on-board temperature sensor of a PCI-6704 data acquisition (DAQ) device?The text below appears in the user manual, but it does not explain how to actually acquire the device temperature? The onboard temperature sensor measures the air temperature URL: http://digital.ni.com/public.nsf/allkb/B04ECBEA61188801862573E7006DD98B

在带缓冲的事件边沿计数仅仅在计数值改变时才写进缓冲区 在M 系列板卡中，带缓冲的事件边沿计数仅仅在计数值改变时才向缓冲区中写数。如果我想对同样的计数值多次读取，我仅仅只能接收到第一次的值，其他读数均返回为空。但在 E 系列数据采集卡上是可以这样做的。 URL: http://digital.ni.com/public.nsf/allkb/39568E1A985033A048257393001F8181

Understanding and Avoiding Overwrite and Overflow Errors with Traditional NI-DAQ I am receiving Error -10845 (Overflow Error) or Error -10846 (Overwrite Error) when performing a buffered analog acquisition using Traditional NI-DAQ.

Understanding and Avoiding Overwrite and Overflow Errors with NI-DAQmx What are overwrite and overflow errors, and how can I avoid them when using NI-DAQmx? URL: http://digital.ni.com/public.nsf/allkb/6C05A002FAE4F9F68625734C0059B4EF

理解并避免DAQmx中的数据覆盖错误(Overwrite)与数据溢出错误(Overflow) 什么是数据覆盖错误(Overwrite)与数据溢出错误(Overflow)，我怎样才能够在使用NI-DAQmx的时候避免它们的出现？ URL: http://digital.ni.com/public.nsf/allkb/EBB4B16EF1EF9D54862573C4001050B8

Internally Routing Counter Signals in LabVIEW I want to route the output signal of one counter to the source/gate of another counter on the same card or to a specific PFI line. Can I do this without externally connecting the two pins? URL: http://digital.ni.com/public.nsf/allkb/8A85E97855EDADC98625730C00065F58

怎么才能够在LabVIEW下路由计数器的输出 我想要将一个计数器的输出路由至同一块板卡上的另一个计数器的source/gate端或者到一个特定的PFI引脚上。我能否不通过外部连接着两个引脚而实现这样的功能？ URL: http://digital.ni.com/public.nsf/allkb/C49A281133F4D39F862573C900442CDE

Why Do I Receive Drift Readings when Using Analog Input on My DAQ Device? When I feed a voltage source through an analog input channel on my DAQ device, I see the voltage drift. Why is this happening when I am feeding the device a constant signal? URL: http://digital.ni.com/public.nsf/allkb/08384B7B2ADD360D862572F1003DEC29
