Where is the Calibration Performed?

[Jordenjohn]

Electrical, Mechanical and thermal industry use measuring instruments. Calibration is a comparion between the measurements and instruments like Pressure Calibrator, Temperature Calibrator, Electrical Calibrator ane mostly used in process line. I know where we use these instruments but where perform the calibration is the question. Please give some suggestion.

What does this have to do with LabVIEW?

Calibration is often done by the manufacturer.  There are also many places that do nothing but calibration.  But I always just left that mess to our calibration lab.

You send the intrument to a calibration service provider, like http://www.sp.se/en/Sidor/default.aspx unless your requirements are lower and some internal calibration/reference is enough.

You can e.g. send 1 instrument for calibration and compare the others to that one.

We often take the easy way out and send our instruments to our internal calibration lab; they send stuff out if they don't have the equipment to test it.  When possible (and, when we're feeling ambitious) we'll develop a cal-in-place procedure to validate only the measurements we use in our application.  This reduces equipment down-time as well as the chance for a validation failure over a measurement that we don't even use.  The only downside to this approach is that the equipment can't be used in another application without first validating it's calibration for those requirements.

It's not really a "downside" when someone else can't steal your equipment. 🙂
