Don't worry about that, I think it's ridiculous that that was suggested to you, there's no reason to think there is anything wrong with the calibration... It does not change even after sitting unused for years normally... You need to adjust your technique and expectations, take time using only it, changing single variables at a time, there are a ton of variables, like I said you are the one creating the vapor the way you inhale so you need to make sure you have the proper heat in the heater and then you are pulling that through to vaporize the herbs so you are going to have to relearn what the temperature settings mean for this device since they are not the same as crafty or other session devices you might have experience with (that have weaker smaller heaters typically and rely on conduction to create the vapor for you instead of convection where you are the one creating it with your inhale)
Sorry, the thread is really cluttered, you would have to skim through the whole thing, not just my posts but other people's posts, about use, because you see when you ask the question here you got a mix of advice that I don't think is very helpful... What you need to work on is technique etc.
If you want to see my posts, there is a search at the top, you can choose to see posts only from a specific member, and type a search term like "usage tips" or just one of those words or other words... It can be tricky that way, or you can try to just use Google and type fuck combustion with your search term for tetra (the original Tubo thread could be helpful as well since they work pretty much the same except tetra has a better heater and other upgrades)
