Just plug it in outside away from anything that emits CO2. If it reads 360 - 400 then it's pretty good to go.

Well the fact that both sensors are very close in reading makes me think its accurate, are you positive that reading isn't correct? Was it outdoors? Are you in a big city where CO2 levels are higher?

You could always use one of those cheap co2 syringe test kits to see if it's reading the same or close.

I plugged it outside next to wooded park away from any traffic. I’m pretty sure it’s not 770.
Thanks

It could very well be that high outside. Seen it myself. Personally I think the unit is working well and if it was mine I would just use it as is.
