data refresh rate OC-CC-apnea

[subone]

Hi,

what is the rate of data refresh in 2N?
In OC or CC it could be some seconds (I do not know) but what in apnea? Is it the same rate in all the diving modes or it changes?
Does it calculate the average depth too?
Does it make the graph of the diving?

Thanks,
Simone

Hello Simone,

Refresh rate (display) is 2sec in dive and gauge modes. Recording rate is configurable, and default to 10sec for depth, 1 min for temperature, ceiling, and GF, 2min for CNS (CF#20 to CF#26).

[EDIT] For apnea, I was wrong... See below !

How is recording rate configurable? Is it one of the lot of custom functions?
I got that display refresh rate is fixed (2 seconds) in all diving modes but display refresh rate is different by recording rate.
You wrote that in apnea the dive profile is recorded every 2 seconds; could I change/custom/configure recording rate in apnea too or is it fixed?

I have some other questions about apnea because I saw the OSTC computer working in OC and CC but I have never seen it in apnea.

I am asking this because I have not a computer for trimix diving at the moment (only for air/nitrox: M1 RGBM) and when I dive with Trimix (OC/ECCR) I use mnemonic deco or deco tables or computer of other divers; at the same time I do apnea so I would like a computer which does everything (air/nitrox/trimix/OC/CC/gauge/apnea).

If I stay 2 ours in apnea and I do 20 divings, does OSTC 2N compute tha average depth of each diving or tha average depth of all the divings done in 2 ours?
What about the graphs? Does it record every dive or I can see only the last?
Could I download apnea dives? Do I have to use some particular stuffs to do this?

Thank you,
Cheers

Hello Simone,
I made some tests at the swimingpool tonight.
* Recording rate is every 1 seconde. Fixed.
* There is no average in apnoe mode.... yet.
* It record successive apnea as one profile (see exampe below) if surface interval is less than 10min (configurable CF#30). Or less if you hit quit.
* There is room for many dives (5h of apnea ?).
* Apnea dives are profiles like the others, and can be downloaded, and replayed by the various softwares (replay and dumps below done with Diving log 5.0.3).

* During dive, you have current and max depth. Current apnea time, and total time:

* At surface, The unit displays total time, last time, and interval since last time:

And the plot of the successives dices, as seen on the OSTC logbook:

Hope this helps.
