Hi all.

Mt HH failed calibration on two brand new cells and i am wondering where I stand on this.

I have three C6 cells three weeks old, and after soaking them overnight in a bag of 02 and doing a bag flushed test I am getting 45mv on two cells and 39mv on the third. Also a cell new in September is giving me 35Mv. The 35 and 39mv cells are not good enough to pass calibration on the Hammerhead.
In air I am getting 9, 10 and 12 Mv on the new cells 9mv obviously being on the cell offering 39mv in ambient pure o2.

So are these failed cells? They cirtainly wont work below 40mv on the HH so why are they OK on the YBOD? Is 45Mv acceptable or are they failed as well?

My old cells are 13months+ old and output 50mv in pure 02 ambient.
