Abstract
The present invention discloses methods for detecting and improving temperature stability in measurements performed by a dry block, i.e. a temperature calibrator. The dry block comprises a heating and cooling device. An energy metering integrated circuit measures an applied input power to the heating elements of the heating and cooling device. Additionally, a real-time compensation algorithm uses measurement results obtained by the energy metering integrated circuit, and outputs a control signal to the heating elements. The arrangement may comprise a back draft damper adjacent to a fan. The fan position may be selected. Stability criteria may be set. Leaning of the dry block can be tracked. Different sensors are used for the temperature control and for the temperature stability indication.
