Abstract

A Peltier element (8) is regulated in order to provide a desired first temperature on a first side (9) of this element in contact with the object (11) in which energy flow parameters are being measured and the element's current and power consumption are also measured. - A second temperature is measured on a second side (10) of the element facing away from the first side and in contact with at least part of a thermal element (12). An INDEPENDENT CLAIM is also included for the system used to carry out this method, comprising a Peltier element, at least one sensor (Ta, Tb) for measuring the first and second temperatures, a measuring device (A, V) for the electrical resistance of the element, a voltage supply (E) connected to the element and a control unit (14) connected to the temperature sensors and designed to regulate the voltage supply in order to provide the desired first temperature.
