How inaccurate is too inaccurate?

[skynscuba]

I have a Datamax Pro Plus which is reading low on the tank pressure, by about 180psi at 3000psi. I have not yet verified what it reads at the low end, so I'm not sure whether there is a zero error, or just a span error. Oceanic doesn't seem to publish any accuracy specs in their manuals, just resolution.

What is the accuracy specification for tank pressure?

The specification is +/- 1%. Suggest you give our guys in Customer Service a call - 800-435-3483.

Thanks, Doug.

It seems that they don't repair the DataMax Pro Plus any more, so just offer a discount trade-in on a ProPlus2. The computer cost me about $5.50 per dive, or more like $9 per dive if I don't do the trade-in.
