O2 sensor question

Is there a Noddy's/Idiot's guiode to oxygen sensors anywhere - did a quick search here but nothing leaps out apart from Mark's problems with his sensors and Kevin's splendid comment:

Last Point: eCCR's are NOT TOASTERS - these things are Life Support Devices, which means that you need to take them more seriously than you would your iPod.


Did a quick check this morning with my Classic KISS and with the Shearwater reading 0.90 PPO2 I get millivolt readings from the three cells of between 45 and 47mv - sound about right?
But with Natasha's KISS and the VR3 to a P-ported cell yesterday we only got about 23.7mv with 1.0 and a 'Cell low' warning. So I guess the cell is probably dodgy, but is the VR3 reliable in this measurement?
And the other cells in her KISS all react very slowly - is this a sign of more current limiting?
(Cells are all R22-BUDs and less than three months old).

Any advice gratefully received.
Thanks

Robert
