Measuring Current with SCB-68 and 6070E

[Fouzaan]

Hello,

I'm new to data acquisition and labview. I am trying to measure current using an SCB-68 box and a PXI system with a NI-6070E card. If anyone could point me in the direction of a tutorial that would tell me the following it would be immensly helpful. I found in the SCB-68 manual that the way to go about measuring current is to measure voltage with a resistor and just recalculate the current. I'm still unsure how to gather a simple voltage though and haven't been able to find a tutorial. Everything is either too basic about labview or too complex.

1. How do I setup labview to gather these signals?
2. How do I know which pins in the SCB-68 box to use?

My apologies for such vague questions, but I've spent the last 3 hours trying to find something that would walk me through the setup but haven't been able to find anything useful. Thanks for any simple tutorials/resources you can point me toward.

Hi Fouzaan,

Using your data acquisition device is made really easy in LabVIEW thanks to the help of the DAQ Assistant Express VI. You can access the DAQ Assistant by going to your block diagram in LabVIEW and accessing it in your Functions palette under Measurement I/O » NI-DAQmx. Once you place this Express VI down, you will be prompted with a wizard allowing you to select the kind of measurement your are trying to perform as well as the channels you want to use. Once the wizard is complete, you will be presented with your task configuration. After configuring your task, you can click on the Connection Diagram tab shown at the top and select SCB-68 as your accessory. You will then be shown a diagram of the physical connections that need to be made to your device in order to take your measurement.

Our website is also a great resource customers can use to help answer all your questions about how to use your DAQ Assistant in LabVIEW.

Thanks S, I'll look into those. they seem to be exactly what I need.
