A method for calibrating a transmitter with measurement circuitry electrically connected to first and second input terminals includes connecting a primary temperature sensor to the first input terminal and connecting a calibrated reference device to the second input terminal. The measurement circuitry is calibrated with respect to the first input terminal according to signals received from the second input terminal while measuring temperature according to signals received from the first input terminal.
