Re: OSTC2 Battery indicator problem after 3.26 update

Hi Emka,

give it a full charge. The battery data reset during the update, it needs an end-of-charging event to calibrate the Bat Indicator for 100%.

Re: Ploywatch? Remove Scratches

Have you checked that there is no screen protector attached to the glas? Sometimes it is hard to see, look at the outer edges of the screen for a jump in "screen hight".

Re: Umkehrdruck

Yup!
Im OC-Modus wird der Luftbedarf für den Aufstieg (inkl. Deko) berechnet.
Im CCR Modus ist eine Gasbedarfsberechnung "auf dem Loop" nicht sinnvoll definierbar,
daher aktiviert diese Funktion im CCR-Modus eine Bail-Out-Gas-Berechnung.

Re: Feature request hwOS Tech: ADD +5

To be preceise, the OSTC will show the "future" Total Time to Surface, but not the complete deco schedule for +5 mins (or whatever you set the look-ahaed time). Internally, during the calculation, these data are available, but they do not get published to the user interface (screen) due to no space ...

Re: Maximum O2 content in the loop

Hi,
the default value is actually 21%, but you can set any value between 21% and 100%.
The set value will be stored, so once you change it to 98% it stays at 98%.

Please check your max ppO2 setting. I suspect 32% 30m aka 4 bar ambient pressure exceeds the current max work ppO2.

Re: OSTC Sport - Need help about display

The OSTC should not compute a deco stop on 0 meters. As the time is rounded up to full minutes, 1' could be anything down to 1 second and hence this whole 0 m - 1' a glitch due to rounding errors. Maybe the surface pressure has changed significantly during the dive, making the OSTC to belive the 0 ...
