wrong temperature and wrong time
Posted: 02 May 2009, 13:40
I have some small issues with the ostc, which now I'm very sure they the wrong values:
1/ The temperature given is always too high, about 3-5 degrees. I'm very sure about this, since all other computers give lower temperatures, and also biologically it doesn't fit - every year, there are sepia's in the 'Oosterschelde' when the water temperature us 12°C. They are there now, just, but according the ostc, the water should already be 15-16°C, which is really not the case. How to cope with this?
Also, but this may not be a real error of the ostc, I see that in every dive, I start at a certain water temperature, and it drops slowly, after 10-20 minutes to a more or less steady value. This seems wrong imho, since, the water temperature is not really dropping slowly. I wonder why the ostc gives the same (rather unrealistic) temperature profile.
2/ A second issue I have with the ostc concerns the time. When I don't dive for 1-2 weeks, the ostc is running behind the real time. It's a matter of minutes. I estimate that it runs 0.5-2 minutes/day wrong. How can this be solved?
Well, I have some doubts about the pressure sensor too (the ostc gives values that are too high, imho, but I didn't check that yet, so that's just a feeling so far). I have always the latest stable firmware version on the ostc, and the 'inconveniences' remain - I don't think it's a software problem.
Thx, Kurt
