Breakpoint Tables

Title: Breakpoint Tables

I have 4 instruments that read differential pressure across V-Cone flowmeters.  The manufacturer supplied us with a 10-point calibration, which covers the desired engineering range.  These devices are not linear, and I think the right way to handle them is going to be to generate a breakpoint table for each (all 4 are sized differently).

I’m looking through the app guide, section 6.17.  Is this the accepted method to generate a breakpoint table?  Since epics was installed through a package, I don’t have the “menuConvert.dbd” file, so I’ll have to download a source archive for that.  Now, it says to copy the menuConvert.dbd file, but it doesn’t tell me where to put it.  In the source directory of the IOC application?
Section 6.13 refers to a ‘breaktable’ command.  Is that an easier way to do this?

How about a simple step-by-step description of how to generate a breakpoint table?
