Retrieve MAX Custom Scale's Units.

[ian99rt]

I've just completed walking myself through Labview for Scientists and Engineers (Essick) and currently building my subVI arsenal to build a multiple 4-20mA sensor automated test stand. 

I currently have a VI that prompts the user for a DAQmx Channel and DAQmx Custom Scale (scale setup with PSI units in MAX)  and provides this to a subVI for DAQmx calls & and data capture. 

The subVI  captures data from either pressure transducers, flow meters, or level sensors. 

The issue I'm having is I want to have my subVI provide the MAX custom scale units (PSI, GPM, Inches, etc...) out to the main VI for when I write the data to a file (with units).

That menu is located in DAQmx -> Advanced -> Scale Setup

Do I have to programmaticly create the scales versus using MAX to use the Scale Property Node (to get the scaled units string) ?

I like having the user interface pulling the  custom MAX scales from the drop down menu.

No.  You need to set the Active Scale first and then the property node will return the scaled units of that scale.
