Abstract
The present invention discloses a method for regulating temperature in a temperature calibrator, taking into account also a velocity of the change of the temperature. The characterizing features are the steps of calculating a rate of change of the actual temperature of the temperature calibrator by a derivator, which derivator takes the measured temperature, PV, by the temperature sensor as its input, and letting a user to specify a maximum rate of change for the temperature, as an input value for the processor; and regulating the temperature of the temperature calibrator by the processor so that the maximum rate of change for the temperature is never exceeded, and so that during temperature regulation, when the temperature error signal decreases as a function of time, also the rate of change of the actual temperature is set to decrease as a function of time.
