OSTC 2n V3.15 Wrong measurement and calculations

[Pioulpou]

Hello,

In a dive, the OSTC didn't start and and the LED below the brand name is not blinking.
The OSTC only started when I plugged the USB cable. It showed the screen in dive mode buth without the current depth.

Then, I rebooted the OSTC with the magnet and it showed this screen :

The OSTC showed the main screen but with bad air pressure and air temperature.

After few minutes, the screen switched off and it was not possible to turn on. The only way is to unplug and plug again the USB cable.

I tried to load again the firmware 3.15 but with no effect.

I tried to simulate a dive (66 m, 21') and the result is not what expected : The calculation started from 260 meters and on all the other steps every 3 m.
It showed the dive plan on the following depth : 17, 14, 11, 8, 5 and 2 m. and then 127, 124, ..., 52m. For the gaz volume the result was =xxxx.x

Any idea how to recover this issue ?
Thanks

Hello,

Quite obviously a defect in the pressure sensor. We still have (few) spare parts for the 2N and are still repairing them. Just get in touch with us: info@heinrichsweikamp.com

Thanks Matthias for the repair.
I am glad to see that after 12 years of service, my OSTC 2N could be still repaired.
Great service from this brand name
