If you aren't leaking more than the amount of air it estimates your mask will leak out the vent holes, it reports zero leaks. It's a severe design flaw in my opinion, but that's what it does. PRS1 machines record both the real leak information and the estimated "unintional leak" rate.

RE: zero leaks
Zero leaks, which value?
Max? probably should NOT believe that. Median? Sure, my median leak is almost always 0. 95%? Maybe. I get 0 for this value a few days per week so someone might do a little better at fitting or the machine might be subtracting just a little more than you mask actually leaks and you would get zero.
Sweet Dreams,
HerbM Sleep study AHI: 49 RDI: 60 -- APAP 10-11 w/AHI: 1.5 avg for 7-days (up due likely to hip replacement recovery) "We can all breathe together or we will all suffocate alone."

RE: zero leaks
You need to leave it unplugged for more than 5 minutes. 30 minutes at least and an hour would be better. There are capacitors in the machine that take a while to discharge.

RE: zero leaks
Is your S9 set for the right mask type?

Plug it in, put on a mask turn it on, unseat the mask a bit. Got air? Got leak.... Does the report show it?
