This express block has an interactive user interface that allows the user to have a customized interpolation table. This table can be written to file but requires the user to reconfigure the express block if a new file is used or the old file is moved.
The workaround is to convert the express block to a VI by right clicking on the block >> show front panel. This will convert the express block to something that can be edited. It is a one way process. If you open the new VI up, you will see that it has a termial for the interpolation table. Now all you need to do is add the express block, Read LV measurement file, to get the data (interactively if desired) and feed it to the newly converted Scale and Mapping VI.
