CT 50 Flight Data Systems

I have a CT 50 Flight Data Systems in my Vans RV 4 and for the last couple of years it has worked fine.

Now, it appears that the gauge is showing it to be 7 degs warmer than it really is. I’ve checked the connections and they are ok.

Is there anyway to calibrate it to bring it back into spec? Any other options? or a new probe?

Thanks

GT-50

They seem to be pretty particular about grounding the black wire coming from the GT-50; Is it possible that this connection has worked its way loose, failed, oxidized some how?

Failing that reach out to them http://www.fdatasystems.com/contact-us
