In Labview 8.6 and MAX, can I edit a scale for a voltage read channel in a task once the application has been built and installed on a second PC. In fact, where is the scale info held?

If you are looking to create a scale that can be edited from within a built application I would like to point you two one of these two KnowledgeBase articles. These articles outline the methods for creating a custom or programmatically set scale.

Thanks for the reply. I have been able to read most of referenced docs. But being old, befuddled and generally thick, I am still unclear as to one aspect.
Once I have the application up and running on a separate computer, is it possible to edit the scale on that computer,. presumably this would be done with MAX. ( This is in Labview 8.6, on DELL PC's, Windows XP, with a PCI 6221 (D37))
Or must I rebuild the application.
(To date, I have only built applications where the user inputs calibration constants. These can then be filed and re-read from ad hoc text files. This has suited since they had very much reconfigurable inputs. The application to hand now has a completely fixed configuration for its transducer hardware, It seems to me it would be cleaner/simpler/safer to deal with only "user units" in the program itself. But the scales would need a facility for re-calibration periodically.)

Once you have built your VI and compiled it into an executable and deployed it on a different machine it essentially becomes a read-only file, meaning that you will be unable to edit the scale within this deployed application.
