I am doing this in a plastic bag and getting exactly the same readings as I was getting on the unit. This makes me think I am doing it OK on the unit.

If your getting it in a baggies it sounds as if you really have bad cells. for dsiplay purposes 8.5mv - 9.4mv will display as 9..
In 100% a cell that is linear will be accepted as it would be 40mv for an 8.5mv cell (at 98% oxygen it wouln't be).. If you arent using 100% oxygen you should build tha cal kit like I use, so that you can properly cal it when not using 100%
yes moving them around the readings should follow.. The mv reading will always give you the true reading.. the po2 readings will be disabled for cells that failed and wrong for others..
it also sounds to check things out I wuld make up a simple harness and do the oxygen in a baggie while a cell is connected to a volt meter..
the appproximate reading should be reading in air * 4.72 * oxygen percentage
