Intermittent channel in SCXI-1520

[dj143]

I have been using an SCXI-1520 and recently channel 0 has become intermittent in operation. It drifts off to either the plus or negative rail and stays there. This problem is noted with and without connections made to it, including the use of the Test Panel function in MAX. Resetting the module sometimes helps, but not for long. It appears to me there is a malfunction in the module, but I wanted to get an additional opinion before I send it in. (An additional uncertainty is that the SCXI-1520 seems a little touchy, or unstable in it's setup. It's just an impression I have.)

Also, is it possible to programmatically reset the module in LabVIEW?

Greetings,

Have you been able to try the module in a different slot or try the module on a different channel? I would also try to see if you can use a different chassis to replicate the problem.

If you consistantly see it, the module could be damaged.

Hope this helps,
Regards,
AnujD.

Part of the reason I don't want to send it in for evaluation is we are using it in production. (We make strain gauge based load cells.) We are expanding operations and so I've ordered an additional module and chassis. However, I will not be able to get to it till January.

I reassigned channels to keep production going until I can sort things out.

Thanks for your response. It gives confidence that I'm not missing something in the programming.
