Abstract
A method for calibrating a control system configured to control a two-wire heater includes providing power to a load electrically coupled to the control system, generating, an initial measured characteristic and a calibrated measured characteristic of the load by the control system and a controller calibration system, respectively. The method further includes defining a calibrated measurement reference based on a correlation of the initial measured characteristic and the calibrated measured characteristic. With the calibrated measure reference, the control system is further calibrated to define a resistance-temperature calibration reference for determining a working temperature of the two-wire heater based on a measured resistance of the two-wire heater.
