摘要： A method for controlling aerosol production in an aerosol-generating device is provided, the device including an inductive heating arrangement and a power source, the method including: performing, during a first heating phase, a first iteration of a calibration process for measuring one or more calibration values associated with a susceptor to heat an aerosol-forming substrate; and during a second heating phase: controlling power provided to adjust a temperature of the susceptor based on a calibration value, re-measuring the value by performing one or more further iterations of the calibration process, the susceptor temperature being adjusted based on the calibration value resulting from a latest iteration of the calibration process prior to adjusting the susceptor temperature, and in response to detecting a puff, preventing re-measuring of the calibration value.
