Not getting expect results with linear tag scaling:  
Raw Low 0 Counts  
Raw High 6000 Counts  
Scaled High 0.1 (1E-01) [Torr]  
Scaled Low 1E-11 [Torr]

Testing with 1200 counts. I'd expect 1E-09 back. I get 2.0E-02

It seems the Scaled low of 1E-11 is too small, when looking at the tag outside the definition the scaled low is displayed as 0, not 1E-11.

OR maybe I'm not seeing something obvious.

Any suggestions?

That is not a linear scale. That is a log scale.
