PP V3 lite power indication not in line with ammount of labour

[black-stallion67]

Since 2 months I have a PP V3 lite which is paired to a Sigma Rox 12. What appears is that with incremental labour the bike computer doesn't show incremental power. Mostly when I make a climb power decreases (even to zero) and on larger decent power indication is extremely high when I don't put any labour in the pedals. I assume this isn't correct...
Where should I look to resolve this?

It sounds like you might be in indoor trainer mode...

The easiest way to sort things out is to download and install the free Isaac software, then post a .ibr ride file here.
