I would like to see this thread open up It IMHO was very informative with a lot of unanswered questions on cell testing and pre dive protocol.

I dive a PRISM and the Unit will not calibrate unless you have 3 working senors and 98.3% or higher O2

One of my pre dive protocols (within 24hrs) is a mv check

If an O2 sensor is producing the proper mv out put can it still fail and not read over 1.6????

I personally believe sometimes less gadgets are better, and there are no shortcuts to ccr diving. If you do a mv check and a elevated PPO2 decent to 9m or a pressure pot test Murphy can still KILL you.

SHAME on any ccr diver who dosnt own a volt meter(it was required for my PRISM Training).

Hi Martin,

The thread was closed by me because of the nature in which it degenerated.

Feel free to go to this new thread

and ask any questions you have, but that one remains closed.

We sometimes all suffer through the short-sighted nature of others.

Hope you understand.

Cheers,

Dave.
