PSI Accuracy in Aeris Atmos ai

[divesergeant]

Can anyone tell me, with actual knowledge, whether the Aeris Atmos Ai psi reading is spot on, or programmed to read 200 psi under the actual pressure as a safety measure?

I'm having the same trouble myself. Mine seems to be more like 3-400 low!!!!! Depth also reads two to three feet deeper than my other computer!!!

[dalyup]

I kinda made a fool of myself by telling a marina I was getting short fills!!!

[sladerer]

My wife has one, so when we dive this weekend I'll use a pressure gauge at the shop to measure
the fill and then see what her AI reads once we connect up.

Mine seems pretty much dead on. It's always right at what I was told my tank was filled to.

[sladerer]

I checked out my wife's this past weekend by using the pressure gauge at DiveTech and
then checking the AI's reading once geared up. It was never more than 100psi off, and I'd
attribute some of that to transport/setup. I forgot to take it with me to the shop to check
directly - I'll try to check it out this weekend.

Have you tried this test at your LDS using a pressure checker and then connecting the reg? If so
and you're getting the same results, I'd definitely consider contacting Aeris about it. They've been
great to deal with the couple times I had issues (or suspected issues).

Yes I hooked two different computers up to the same tank and they were within 20 pound of each other. Mine showed 175lbs low

funny how Aeris has not responded to this thread. Mine is also reading 225lbs low, and I'm NOT very happy about it.

My wife has the Aeris AI. For my sanity I have also mounted an SPG on her regs so I can easily see how much air she has left. Frankly I've never noticed a difference between the spg and the computer. The computer is maybe 25-50psi low, but the spg markings are something like 100psi. I'd call that an acceptable margin of error.

They dont really care about responding in this forum unless it makes them look good. I gave up trying to use this forum to get any answers from them.

[sladerer]

It's certainly more of a pain than posting on the board, but I've always gotten great service
from Aeris when I've just picked up the phone and called.

Thats better than it reading high.

Has anyone gotten this issue fixed from Aeris? Mine is out of warranty but reads about 250 psi light.

[Jim-SAR]

My AI is doing the same thing. About 250 psi low.

I called them today, and they said that I could send it in for a flat $150 fee that covers a full overhaul, calibration, and testing. He said once they open them up, they're required to do a full re-manufacture on them.

You have to call, get an RA(return authorization) number, and fill out a form to send with it. They said it's about a 10 business day turn-around in the States. Here's a link:

Now if I could only get the download cable to work and not timeout.

The transmitter for my 750GT reads 250psi lower than both my test bench and my backup SPG. I've seen many, many Aeris/Oceanic transmitters reading that much lower than actual. I advise my customers that they're that low so they'll know and can plan accordingly. I have to agree that I'd rather have my transmitter read low than high. My SPG reads a tad high against my test bench and it helps to know that, too. I'm a service tech and see these transmitters regularly.

I haven't had enough experience with other manufacturers' transmitters to comment knowledgeably on them so I won't.

Oh wow - here I thought my transmitter was just bunk...mine always reads 250-300 less than my spg...Many times I appreciate it though for the additional "padding" it gives me...however absolutly hate it when doing easy shallow dives...$150 for a rebuilt transmitter seems a bit much, especially since it seems like it happens to so many of their units...
