Abstract
An electrically operated aerosol-generating system may be configured to detect adverse conditions (e.g., a dry heater). The system may comprise an electric heater comprising at least one heating element for heating an aerosol-forming substrate, a power supply, and electric circuitry connected to the electric heater and to the power supply and comprising a memory. The electric circuitry may be configured to measure an initial electrical resistance (R) of the electric heater; measure a subsequent electrical resistance of the electric heater after the measurement of the initial electrical resistance; determine the difference (ΔR) between the initial electrical resistance and the subsequent electrical resistance; determine that an adverse condition is present if the difference is greater than a maximum threshold value (ΔR) or less than a minimum threshold value (ΔR) stored in the memory; and control a power to the electric heater and/or provide an indication if the adverse condition is present.
