OSTC Mk2 : pressure and depth accuracy

Post by patrick »

Hello,
I fully enjoy the OSTC Mk2 : readable, easy to use, easy to set, software updates and so and so.
I have a question about pressure, depth and deco calculation about which I didn't found an answer among the topics.
My OSTC Mk2 pressure indicator is about 1% above the official pressure since I received it. At the present time : 1031 instead of 1019 mbar plublished by Meteo France for my location, at the ground level.
The depth is under the known reality (Nemo and others) : Nemo 33 M instead of 35 M.
Salinity set at 1.00 kg/l
Thus 1% of pressure inaccuracy is certainely acceptable, does :
a) the depth measurement is impacted by it ?
b) the deco plan is under calculated due to the measured depth under the actual one ?
Thanks,
Patrick
