If you need to make adaptations to accommodate specific beans, do not do this by altering calibration. See Uneven roasting .
Roasting at High Altitude
When you are situated at a high altitude and are roasting on the Nano7, the motor will need to spin faster in order to push enough of a volume of air through the beans in order to achieve optimal flow. This can sometimes lead to the calibration on the roaster being higher than normal.
If your calibration number is above 1.10, then please reduce your dose by 20g and repeat the above calibration protocol. This will mean that your roaster will be calibrated for 100g instead of 120g. If you dial back your batch size and optimal flow occurs at a value above 1.10 again then reduce the dose by 20g, and repeat the calibration protocol again. Continue this process until you have achieved ideal flow under a value of 1.10.
Remember that while at this high altitude calibration your standard dose will be different from the standard amount, however all profiles shared with you should work the same as anywhere else in the world.
