co 00 1 The invention relates to electronic measurements and can be used in many industries where it is required to control parameters of different physical nature. The aim of the invention is to improve the accuracy by replacing the measurement operation of a test value, compiled as a sum of the measured value and an additive test parameter, with an exemplary measure measuring operation not related to the measured value. The device consists of a filter 1 and a transformer 2 connected in series, a digital recording device 3, a computing unit 4 and a display unit 5. The device works as follows. Thermopower E corresponds to transmeter 2 corresponding to the radiation level Q perceived by the receiving surface of transmeter 2. First, thermoEMF EQ is recorded by the recording device 3 corresponding to the radiation value Q x- The measurement result is entered into computing unit 4. Then filter 1 is placed under the receiving surface of transmeter 2 which reduces the radiation flux by a factor of K (for example, an IKS-2 glass filter with a thickness of 1 mm — at a radiation flux with a 282 wavelength of 2.1 μm, has a transmittance of 0.87). Thermopower E (j (corresponding to the value of radiation K Q) is recorded by recording device 3. The measurement result is also entered into computational unit 4. Next filter 1 is removed. Recording device 3 records thermoEMF E Q corresponding to exemplary value of radiation Q | (as a standard measure Q can be used at night zero radiation, or given radiation from the lamp installed above the receiving surface of transmeter 2. The result of the measurement is again recorded in exponential unit 4. The latter, based on the system of equations Q., + QX: ,,, a, +, determines the true value of radiation Q) (from the ratio. / () E., "- E + (E" to L / V,, H, Value of radiation Q from the output the computing unit 4 enters the display unit 5 of the desired result, which in this case does not depend on the parameters Q and on the static conversion function.
