I'm new to this forum and new to roasting with a drum roaster. I had been on a coffee crafters artisan 6 for several years. now have a WK-2 from Wintop. My question is on how to read the gas pressure. Watching numerous roasting videos, I hear people say, "gas is on 2kpa, or 5kpa." I don't understand how to read that on my machine. Maybe I'm still too much of a novice to understand. Can anyone tell me ow to read this? What "kpa" would I be at in this photo? Is this dial 1.0 = 1kpa? 2.0 = 2kpa? If so, how am I hearing others say they're at 5kpa?

Any help or direction would be greatly appreciated! Thank you.
