I recently ran the calibration cycle on my Trident and it got me wondering why it was necessary to prime the sample line before and after switching to/from the calibration fluid. Seems to me that the Trident must evacuate the sample line every time it does a test since it doesn't want to test the fluid left over in the sample line from the last test.
So why is priming necessary? @JimWelsh
