Channel Names Cause Incorrect Analog Output on NI USB DAQ Devices When generating a voltage on the analog output of my USB devices (such as the USB-6008/9, cDAQ 9263) I notice that if the channels in my task have a numeric value at the end of the channel name, then I generate incorrect values. Why is this and how can I fix it? URL: http://digital.ni.com/public.nsf/allkb/061D00FB903F2F6586257361006C5505

Full Scale Current Output for the NI 9265 on Startup I have NI-DAQmx 8.6 installed and on startup my NI 9265 in a cDAQ chassis outputs full scale current (20mA). How can I fix this since the power up state of the card should be 0mA as written on the specification. URL: http://digital.ni.com/public.nsf/allkb/C86C74450F5B78518625735A0056C8C6

Why do I see Voltage Offsets in NI 9237 Acquisitions when Connecting Additional Strain Sensors? While measuring strain from a channel on the NI 9237, if an additional strain sensor is inserted into an available channel on the module it may cause other channels to see an offset. How can I correct this offset? URL: http://digital.ni.com/public.nsf/allkb/57BEE29D9B9331BE482573530078D386

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
