Ductless Mini-Split air flow verification testing, how to do it?

I have been watching videos about air flow and how to calculate air flow with the hotwire anemometer and the vane anemometer.  What I have not been able to find is how to use one of these tools to check/confirm air flow through a ductless mini-split unit.  Has anyone ever performed this test or seen any guides published from leaders in the industry like Bryan?
