Your FAQ says this:

Changing the Calibration Factor for Hanna Meters (HI98311 and HI98129)
[...]
Press MODE button, the Beta factor will appear. DO NOT CHANGE THIS, it should remain at 1.9.
[...]
Your Hanna meter is now ready to be calibrated using the Genesis calibration solutions.

But, when I use that Beta factor, my readings seem to be too high. Are you sure this isn't a misprint? When I use a Beta factor of 2.1, then my calibration seems to be successful and I get the readings I expect (on the Genesis 1413 us/989ppm solution).
