NI 9237真实的激励电压与指定电压值不同
在用NI 9237创建Strain或者Custom Voltage with Excitation的DAQmx任务时,在任务中指定的激励电压与我在Ex+和Ex-两端之间测到的电压不一致。例如,在创建任务时,我指定的激励电压为6V。然而,我在Ex+和Ex

Why Am I Getting an Unexpected Reading With My NI-9211?
I am using a NI-9211 to read a thermocouple or other low-voltage signal. My signal is within the ±80 mV specification of the NI-9211. Why am I not reading the expected input temperature or voltage?

Actual Excitation Voltage of NI 9237 Differs from Specified Voltage
When creating a DAQmx Task for Strain or Custom Voltage with Excitation with the NI 9237, the excitation voltage that I specified in the task is not the same as I measure across Ex+ and Ex-. For example,

NI 9237實際的激發電壓(Excitation Voltage)與指定的電壓不同
當使用 NI 9237 建立 Strain 或 Custom Voltage with Excitation 的 DAQmx Task 時,我所指定的激發電壓與我直接去量測 Ex+ 與 Ex- 的電壓值不同。舉例來說,若我指定激發電壓為 6V,而我所量測到在 Ex+ 與 Ex- 的壓差只有5 V。為什麼實際的激發電壓與指定的電壓

为什么我最新的cRIO模块不能被LabVIEW FPGA 1.1检测到?
我正在使用LabVIEW FPGA 1.1,同时我添加了最新的cRIO模块(NI 9203、9205等等,参看下面的链接)。当我进入'Embedded Project Manager'为CompactRIO配置目标并点击'Discover Modules'时,所有的老模块都能被发现,可是插有新模块的插槽却报告'Unknown'。我也尝试着在一个空槽中手动添

Why Are My Newer cRIO Modules Not Detected By LabVIEW FPGA 1.1?
I am using LabVIEW FPGA 1.1, and I have added one of the newer cRIO modules (NI 9203, 9205, etc. See list below) to my bank. When I go into the 'Embedded Project Manager' to Configure Target for CompactRIO and click 'Discover Modules', all of my older modules are found, but the slot that holds the
