Re: Simulator

Hi James,

are you sure to have set the GFs the right way? GFhigh should be higher than GFlow. I'll try to repeat your calculation. Anyhow, especially as a CCR diver, you should update to 2.26 - it contains many improvements!

Re: Helium Halftime

Hi Mark, you can't change the half-times nor the a and b values for both N2 and He - they are hard-coded into the OSTC Firmware. According to Buhlmann's books, you can set up a ZH-L model with different numbers of compartments. Over the time there have been implementations in dive computers with 8, ...

Re: Desaturation times

Hi all, even if the last post is quite old now, just to close this thread: If the surface pressure has changed between the two dives, the desaturation time will be recomputed according to the new pressure. If the surface pressure reduces, your tissues will offgas faster. So to say, bad wheater (low ...

Re: Funktionswunsch Unterscheidungsmöglichkeit OC/TX/CC im Logbuch

Hallo Daniel,

dein Wunsch wurde gehört, mir ging es genauso! In der nächsten Firmware wird zumindest schon mal auf der erste Seite (die Grafik) in den oberen Bereich geschrieben in welchem Deko-Modus der Tauchgang durchgeführt wurde.

Viele Grüße,

Re: Temperaturanzeig bei <1 Grad Wassertemperatur

Hallo Fredy,

Re: Dekostop Berechnung hängt hinterher?

Damit kann der erste bei 99 Metern liegen, gemessen an der maximalen Einsatztiefe von 120 m sollte das reichen. Die Anzeige der Stoppdauern ist auf 255 Minuten pro Stopp begrenzt, intern daue...

Re: hwOS Tech: 2.26 released

Thats why they are in now in both GF and non-GF mode: with the GFs you can shape your deco stops and with the sat- & desat-factors you can increase your calculated overall tissue load to e.g. compensate for cold water conditions or personal dispositions, etc.

Hi, to start with the easy things: you will need a tech Version, which supports up to 5 OC trimix gases, provides full blown deco calculation functions and also CCR / pSCR diving with additional 5 trimix diluent gases if you will go that way any time in the future. The next question you have to deci...

Re: Mod for first gas is wrong

Hi all,

meanwhile, there are two settings, a ppO2 bottom max and a deco max, which are used dependent on the gases configured as deco gas or something else (first, travel).

Re: Dive number truncated if > 999

Hi,

it's a problem specific to the french language option - the text "Num. 1er plonge" at the beginning of the line is just one charater too long so the last digit of a 4 digit numer gets written outside the screen area. I'll send Matthias a bug fix.

Hi stryke, from the code point of view, that's not possible: during the ascent, the deco plan is constantly re-computed, and when you surface it's gone.
