Abstract
A method of dynamically calibrating a heater having a plurality of zones defined by one or more resistive heating elements includes controlling power to a heater having a plurality of zones based on a dynamic resistance-temperature (R-T) model to control a temperature of the heater to a temperature setpoint. For each of the plurality of zones, the method further includes measuring a temperature of a respective zone based on a resistance of the resistive heating elements of the respective zone and the dynamic R-T model, measuring a reference temperature for the respective zone, and incrementally adjusting a resistance value associated with the temperature setpoint provided in the dynamic R-T model for the respective zone to a calibrated resistance value. The method further includes providing the dynamic R-T model that correlates the calibrated resistance values of the plurality of zones with the temperature setpoint as a calibrated R-T model.
