S9 auto set with zero leaks. This is a glitch right?

The S9 series subtracts out the "intentional leak" rate from its data. 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.

First thought ... unplug, wait, and plug
But is zero also showing for maximum leak? if yes ... aliens again

Whatever float your boat Coffee
I think it is great stuff reporting unintentional leak

Speaking of design, S9 series won the red dot award when first launched back in 2010

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.

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.

Is your S9 set for the right mask type?

You probably need to plug it back in then decide....

How do you feel? Good? Ahi looks good? All else fine?

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

Where are you getting zero from?, if from the machine sleep report screen ... that is the 95% percentile unintentional leak
You need to get the maximum leak from ResScan statistics

At times, I had zero 95% but the maximum a bit higher
