problem setting up ppO2 mode

Post by weirdo1 »

I seem to have a little bit of trouble setting the OSTC om fixed ppO2-mode:

In dive mode the chosen setpoit is displayed and the OSTC seems to work, but the no-deco time stays on 160 min all the dive!

In surface-mode the OSTC shows after the dive 0:00 no-flytime and 0:00 desaturation time and the saturation graphic is clear/empty.

OC-mode works fine. What am I doing wrong or how do I setup a fixed ppO2 divemode that works???

Hello,

Can you give some informations about the firmware version and your settings (SP, Decomode, Depth and Diluent settings)?

regards,
Matthias

I was running FW 1.17 ( just updated it to 1.20) so I can?t check all the settings/ played with the setting since, but al the gasses were set on AIR (21 % O2 dill) and setpoint was set on 1.2 in ppO2 mode.

Pp02 was shown in divemode, so I guess it was setup for fixed ppO2 diving???
I?ve done a couple of shallow dives 20-15 mtr.

There is no WIki for setting up ppO2 mode, so I?m a bit in the dark here.

Hello,

It's straight forward:
- Set Decomode to one of the "CC" modes (ZH-L16 CC, for example) in Menu->Setup->Decomode
- Check if "CC" and the SetPoint are displayed in Surfacemode
- Configure Diluent in "Gas Setup" (Diluent is the "Start Gas" out of the five gases)
- Configure SetPoints 1-3 (Unit will start with SP1)
- Start Simulator (at PC) and descent to 30m
- You'll see a NDL < 160'
- Switch between SP1-3 or Bailout 1-5 with the Divemode menu


Regards,
Matthias

I simulated a dive where the OTSC did not function properly on Fw 1.20 and the OTSC calculated saturation correctly, got de-saturation time and no-fly time.

I hope it will function next (real) dive

Did a real dive yesterday; it worked fine. I guess it was a settings problem...
