Input of "cpp5" –ENTER starts 50 mbar calibration of the pressure sensor
near the patient:
Cpp5
Start calibration FlowCal=0 PO2Cal=0 PPatCal=35 PRedCal=0
The new values must be saved after calibration!
To this end, set the option SAVE SETs to YES in the A
LIA menu.
The new calibration value is only accepted after leaving the OPTION
menu!
6.3.2 Maintenance of the patient part
The inductive resistance in the patient part of the
ALIA device must be
checked with a multimeter at six monthly intervals. The measurement is
carried out at the two upper horizontal jacks on the patient part. If the
measured resistance is less than 115 Ω or larger than 125 Ω, then the
magnetic coil has to be replaced.
Remove the front panel of the patient part every six months. Clean all
loose accessible parts with a suitable cleaning agent, e.g. alcohol.

We draw attention particularly to the need for intensive cleaning of the
inner part, the coil body and the magnetic core. In the case of pronounced
wear (mechanical drive), replace the PEEP valve plate with axis and coil
core.
