Is there a setting to allow the partial pressure to be displayed? Thanks

I should have mention it's for the OSTC 2n

partial pressur of what?

If you check the manual for Custom Functions you will find parameter CF19:

CF19:Upper threshold in 0.01Bar for ppO2 display in dive mode
This value sets the upper threshold (in 0.01Bar ppO2 steps) when the current ppO2 level should be displayed in Divemode.
Default setting: 150 (1.5Bar ppO2)
Example: CF19=150 - When reaching 1.5Bar or more ppO2 the value is displayed during Divemode
This is critical custom function! If the value is above 150 a warning symbol is displayed permanently during Surface- and Divemode. Do NOT dive with a OSTC configured that way!

Hi.
That's great thanks. So if I set it to 1 then it will show the value all of the time?
Many thanks, Matthew

Feel free to try it out
Just use the simulator mode - so you can check if it works the way you like it

It seems that I am unable to change the default setting of 1.5

L = left button
R = right button

Did you find CF 19 in the setup / custom functions menu on your OSTC?
Ok then
press L
change from + to - by pressing R
press L to go down one step
press R to change the step from 0.01 to 0.1
press L two times to go down to current
press R to change the current value to the one you'd like
press L to go down to exit
done

otherwise you can install JDivelog or OSTC-Planner. With both software you can change all CF very comfortable on your Desktop or Laptop computer...

Hiya,

I had found it and it works well.

Many thanks

Matthew
