Hi all at Heinrichs Weikamp,
Just back from a diving holiday in Sharm el Sheikh/Egypt(before I went on holidays havent't been in the water again with my ostc, but did a couple of testdives via my laptop and seemed to be ok, and kept my ostc in handluggage at all time during the flight).
Done a couple of tech dives there...
But not with my ostc...
Day one was a recreational(max 30 to 35m depth on AIR) day of diving where I was going to test my ostc to make sure he was ok, and putted on my old suunto mosquito and bottom timer too as backup, normal dive profile, no decompression dive).

During the dive my ostc was OK.
Surfaced, rinced my ostc in a bucket of fresh water, went up to the sun deck and put my ostc in my backpack in the shade.
Went to the bar on the boat to get myself a bottle of water, and went back to sundeck to have a look to my logbook on the ostc to put everything into my "paper" logbook and heard something beeping in my backpack...

It was my OSTC , he was diving again on the surface at a depth of about 12m( and when he went back to surfacemode, nofly stayed on zero , but desat goes up all the time, and the mBar reading stays on 2277 all of the time), diving logbook had no dives registered, so i couldn't delete the dives, even went to the menu and did a reset all,tried changing the settings from GF/OC to normal OC nothing canged...)

Since we were going to do some tech dives the days after , I asked the manager of Tekstreme diving if he had the software for the ostc on his laptop, yes he had, since he has been using yhe ostc for a long time also...(although he still uses v1.22)
Tried with putting on v1.30 again, uploading ok but got following message on the OSTC:
Unexpected reset from Divemode!
Please help and report the Debug information below:
rrFrZc. 13 11
128 48 0 131 128
0 0 0 192 0

I haven't used my ostc again during this trip , but did my dives on my good old back-up bottom timers...

can anyone tell me what the above debug information means , and what it means to my ostc(?sent it back to Heinrichs Weikamp for further investigation?)
Since it is the second time i get these "false" mBar readings (sent my ostc back the first time and new pressure sensor was put in it , real good and fast service on that one thanx again for that, everything seemed to be ok if I simulated a dive then, but with a real dive it went wrong again after surfacing...)


Thx in advance,

Alain.

After 8 years my Suunto Cobra failed so I have to buy a new computer. I'm doing extended range dives right now and wants a computer with gass switch. I don't have the OSTC but follow the forum every day.
End of june i'm also going to egypt and by then I need a new computer but of course I don't want to end up like Angelain.

So I'm very intrested in the reason why the OSTC failed and the bug fix.

Hi Alain,

Have you tried to re-install the firmware already? If the problem continues I think this is more a hardware problem then a software issue. Please contact us directly about this issue then: info@heinrichsweikamp.com - We'll take care of that immediately.

regards,
Matthias

This seems another sensor problem.

How are the depth sensors soldered on the board?

Does the process involve the whole board been cooked/heated up, or is each component soldered individually?

What temeperature would the depth sensor be exposed to during fitting on the board?

Hi OSTC fan,

I don't know if it's soldered or cooked/heated up.
I'm a technician, but I don't like opening/tampering divecomputers myself, I leave that to the pro's.

I think that's a question that you'd better ask to heinrichs/weikamp.
after all they are the manufacturers that built it.

As for my OSTC, a solution with which I am very pleased has been offered.
Again a big thank U for the very quick response from Matthias.

That's what I like about Heinrichs/Weikamp, they don't leave you just standing out there in the cold.

bought the OSTC 3 weeks ago, tested it in belgium and worked very fine.
Went to egypt. First dive no problems. Second dive OSTC was stuck on 29,6m. Had a laptop with me so I could make a reset but I couldn't make the OSTC working agian. Lucky a friend had a back-up computer with him so I could make all the other dives with his computer.

I'm just back and will bring the OSTC to my reseller.

Washed the OSTC with fresh water after the dive and stored it in a cool place. Is it possible it has something to do with temperature?

Hello Steve

Strange indeed, as I had this in Egypt too.
Could it have anything to do with the high air-temperatures or maybe something with the pressure at sea level in Egypt(maybe it's higher because of the higher temperatures??)or maybe with the high salinity factor of the water in the Red Sea??
As for me I don't think so, because the tech instructor at tekstreme had an ostc too, and has never had any problems with it..
It's a mystery...
The curse of the Pharaoh's????
Greetz,
Alain.

Hello Alain, hello Steve,

strange indeed. My OSTC worked fine in Egypt in january this year.
