Dive not registered in logbook

Hello,

I have done a dive today. All ok.
When I was on the surface I saw that on the screen indicated me to choose if the battery was new, rechargeable, etc. I suppose that the contacts have been touched with the fold or ring of the dry glove and it has arrived at that screen without me being aware ...

Re: Maximum O2 content in the loop

Hi Ralph,


In the OSTC manual you can read that it can be set between 80% and 100%. In fact, in my OSTC I can only set a value between 80% and 100%. I cannot set a value lower than 80%.

Anyway, I would like to know what this set refers to. Could you explain a bit more?

Also whether it should have ...

Maximum O2 content in the loop

Hi,

Could you explain this setting in a little more detail?

In my AP Inspiration, when I am calibrating O2 cells, the OXIGEN % is requested. It is requesting the oxygen % in the scrubber lid after the oxigen inject take place during calibration. Default value is 98%.

It is not clear to me that ...

Re: M.Bubbles

Hi,

I've already found where the problem was.
In setup I did not put the depth of the SP change. Default= 0 m.
So the whole dive was done with a low SP of 0.7

Thanks

Hi Matthias,

First of all, thanks for the quickly respond.

I'm sure that for the OSTC deco stops has been omitted, since the whole dive was done with 0,7 low SP, which greatly lengthens the deco times.
However, the truth is that the dive was made with 1,3 high SP and all deco times and ascent ...

Hi,

4 days ago I did a CCR simple practice immersion. I used the OSTC as backup computer and setup the OST as Auto SP.
My guess is that the OSTC didn't automatically change from low to high SP because the TTS was much higher than the vision of the AP inspiration.
I have to look why it doesn't ...

I realize a couple of details:

I know it's no usual but I like to use a gas that pulls me off the bottom in case of problems with the bibo (emergency gas).
I could not use it if it was not necessary, and then I would have 4 gases, one of the four would also be the travel gas.
But I also want to use the emergency ...

Gas density

Hi

How does OSTC calculate gas density for a given respired gas at a given depth?
What air and the individual components of gas mixes density values does the software use to calculate it?
Does it take temperature into account?

Thanks.
