This morning, I installed our last spare Tsoilx4 at soil.b.  However, I want to give it some time to settle before using it.  So, swapped connections with the old Tsoil.b from 10:50-11:02 (note that the new probe has ID23) to get a baseline difference.  I then went back to the old Tsoilx4.  My plan is to do the real switch tomorrow.
