The Carefusion devices, the calibration was done through the pump. Have you tried contacting Carefusion sales to see if they will sell to you. At a stretch; if you just need syringe size calibration you could try using the relevant size BD syringe? Verify diameter with calipers.
B.Braun, you do need the correct version of HiBaSeD to go with your device firmware version to complete calibration. Verification is completed on the pump but you'll need their physical service key to fully complete 'Technical Safety Check' (TSC). They may sell you the hardware but as Malcolm has said, you need to be registered with them to be able to access their software downloads.
I have no maintenance experience of the Fresenius other than Pilote pumps - sorry.
A man may fight for many things. His country, his friends, his principles, the glistening tear on the cheek of a golden child. But personally, I'd mud-wrestle my own mother for a ton of cash, an amusing clock and a sack of French porn.
