Overpressure going way over max
RE: Vital Signs/Multi-Parameter Report Post

I'm not sure, but if your pressure readings are accurate (PT1 and PT2 are reading correct values), I'd guess it's the release valve not opening properly, but it could the main board not signaling it on time. I could be wrong, but I'd try a new pnuematic kit first (especially if the unit is old) and then the main board.

Overpressure of PV-01 may occur if the source (upstream or downstream in the case of back flow) pressure exceeds PV-01 design pressure.

I have a total of about a dozen of these and I have tried 5 of those and so far all of them are all doing the same thing. Granted they are all old units. Putting in new pneumatic kits in all of them seems a bit expensive and time intensive. Is this common for these units when they get old or is there a way to recalibrate it?
