Issue Details

How do I set up Open/Short detection for my IEPE sensor in LabVIEW?

Solution

You can use a DAQmx Read Property Node to detect overcurrent or an open channel in your device using the properties below.

Shorted Channels
Open Channel  
The snippet below shows the implementation in an IEPE Accelerometer Task.
 

Note: This image is a LabVIEW snippet, which includes LabVIEW code that you can reuse in your project. To use a snippet, right-click the image, save it to your computer, and drag the file onto your LabVIEW diagram.

Additional Information

Refer to Overcurrent Detection and Open Current Loop Detection  in the NI-DAQmx manual for additional information.

Refer to your device's documentation to verify it supports Open / Short detection.
