Just curious...
Has anyone seen the values differ between the handsets unless something drastically wrong ?
From memory, I would say slight differences, yes, I also check by looking at them both, that one (or both) hasn't been inadvertently switched off.
I teach my students, and practice myself, that at the point they check a handset and see it is switched off, before checking the other handset, they immediately do a flush. Diluent at depth and O2 on the surface.
