How can I add the proper units to my Arithmetic Channel Calculation?

Arithmetic never assumes to know what the units of your calculation should be, and therefore always defaults to units of "V." 
Adding units to an Arithmetic Channel Calculation is very straight forward. On the bottom left hand side of the Arithmetic Channel Calculation dialog, there is an option to add Units to your calculation.

If you unit is not listed in the default list of units, you may add your own unit by selecting "Define Unit."
