I have a problem when trying to calibrate the pressure transducer on a 572 infusion pump. The process involves having to remove the internals from the case so you can get to the adjustable pots. Because you do this you need to use an extender ribbon cable. I am constantly getting the 'Fix me 3' error when using this cable. I have tried different pumps and even a brand new cable but the problem is still there.
Does anyone have any ideas/experience of this?

Thanks
Simon
