I have a airsense 10 from resmed!
However My transformer has died two nights ago, and i have spent 2 days in zombie mode.
I found a s9 om secondhand a while back, where the power suply works, but something else isnt right with it.

The s10 and s9 both require 24v and 3,75A, however the Contact isnt the same!
As I cut my cord i realized, you dont simply have a positive and earth cable but 3 different cords.
I would assume that the centrum pin is earth and then you have one voltage inside the cylinder and another one on the outside!
But if anyone with a s10 could check their Contact , i would really appreciate it!
So s10 voltage between centrum pin and outside of the cylinder
Voltage between centrum pin and inside the cylinder, alternativly inside and outside of the cylinder!
Please let me also know IF centrum pin indeed in Earth!
