为什么当连接应变片到另外一个通道时，9237原通道就会有一个电压的偏置? 当使用NI 9237的一个通道来测量应变时，如果再接一个应变片到其它的一个没有用到的通道，会导致原通道有一个电压的偏置，我应该如何校正这个电压？ URL: http://digital.ni.com/public.nsf/allkb/E5285A437CDB85B18625735B00409217

Advantages of the NI 9237 Over the NI 9219 in Strain Measurements I will be using CompactDAQ or CompactRIO to acquire data from a strain gage. My two options for modules are the NI 9237 bridge module and the NI 9219 universal analog input module. What are the advantages that the 9237 has over the 9219?

在应变测试中使用NI 9237比使用NI 9219的优势在哪里？ 我想使用CompactDAQ 或 CompactRIO 从应变计中采集数据. 我有两个选择，一是使用NI 9237 电桥模块，一是使用NI 9219通用电压输入模块 . 使用9237比9219的优势在哪里? URL: http://digital.ni.com/public.nsf/allkb/E194B4871C42846E862573C4003A2AC2

量測 strain 時 NI 9237 相對於 NI 9219 的優勢。 我預定使用 compactDAQ 或 compactRIO 量測 Strain Gauge 的資料。NI 9237 橋接器模組與 NI 9219 通用類比輸入模組都是可以滿足我的需求的選擇。我想了解 NI 9237 優於 NI 9219 的地方。 URL: http://digital.ni.com/public.nsf/allkb/E4B6B7E2D19676D6862573490037056F

Is the NI 9481 Relay Module Normally Open or Normally Closed? I have the NI 9481 4-Channel Relay and in the specifications it says the relay type is single pole single throw (SPST), however it does not specify if the relays are normally open or normally closed.

Can the NI 9401 be Configured for Bidirectional Digital Signals? I know that the NI 9401 has eight digital lines. Can this module be used for counter inputs, digital inputs and digital outputs simultaneously? URL: http://digital.ni.com/public.nsf/allkb/4828F9A252F081758625731E007D85F9

NI 9403 Over Current Protection When I tie several of my NI 9403 DO lines to ground, the module no longer functions. If I remove the shorts the module will then function as expected. Why does this behavior occur? URL: http://digital.ni.com/public.nsf/allkb/EC4E9B0A2F7A97D3862572FD006B7D9C

Why is There Skew Between Output Lines on the NI 9403? When I view the outputs on my NI 9403 I noticed there is a skew. Why does this skew occur and is this expected behavior of the module? URL: http://digital.ni.com/public.nsf/allkb/9C7F202AC28A69D2862572FD00704A0E

왜 NI 9403 의 출력 라인들에 스큐가 생깁니까? NI 9403 에서의 출력들을 자세하게 보면 스큐가 생기는것을 확인할수 있습니다. 이 스큐는 왜 생기고, 이 모듈에서 원래 일어나는 현상입니까? URL: http://digital.ni.com/public.nsf/allkb/0E550E7C6D530F598625730D0001A3A9

Where Can I Find The Warranty For My NI Hardware? I'm trying to find the warranty information for my NI hardware. Where can I find it? URL: http://digital.ni.com/public.nsf/allkb/8341879DC763DF5886257289005D816E
