Abstract
The article deals with an algorithm of problem solution which gives the possibility to fix temperature values in terms of the results of resistance measurement, based on the use of regularization method. Calibration coefficients and estimated errors of solutions obtained are found; criterion which makes it possible to assess resistive thermometers condition in the process of operation, is given.
Keywords
