NI-9234 connection check

[mirza11]

I use a NI_9234 DAQ.

How can i check that my accelerometer connected  to Ni_9234 module is (i want to check this in Labview).

mirza11,

The simplest way to verify that your accelerometer is connected correctly is to use a Test Panel in Measurement & Automation Explorer (MAX).  To do this, open MAX and select your NI-9234 in the left-hand column under Devices and Interfaces.  Next, click the Test Panels… button at the top of the screen.  Set the channel name and configuration settings to appropriate values, and click Start. 

Good luck!

I check it in MAX. 

But i want check it in Labview program.

While my application is in running mode , if an acceleration  sesnsor connection failed, How can i detect it?

mirza11,

I've attached an example program that will continuously display accelerometer data on the front panel.  You will need to set the accelerometer parameters to match the values from your accelerometer's datasheet.  The NI-9234 provides 2 mA of excitation current, so I set this as the default value.  The error wires along with the General Error Handler VI will report any connectivity errors with the 9234 itself.  The data from the graph should provide a good indication if the accelerometer itself is working.  I'm not sure which version of LabVIEW you're using, so I saved this VI in LabVIEW 2009 so it can be opened in 2009, 2010, or 2011.  Good luck with your application.

It was Ok.

Thanks.
