ABSTRACT OF THE DISCLOSURE The invention provides a process for determination as to what tolerance range is permissible as independent factor in the combination of the process and condition char- acteristic parameters to ensure the dependent factorial value within the tolerance range specified for one, or several qualitative characteristics of the product obtained as a result of the process, in case of technological pro- cesses characterized with multi-factorial technological parameters, in the course of which by setting the indepen- dent factors of the technological process to experimental value, then changing the setting as necessary, the momen- tary values of the independent factors are measured and the dependent factor(s) is/are measured continuously, by sample taking, and/or as final values, by processing the measur- ing data as necessary with microprocessor the dependent factorial values corresponding to the various value-combina- tions of the independent factors are determined, the result is displayed on the video screen, the process characteris- tics are modified as necessary according to the visual eva- luation of the displayed image and this process is repeated until the searched final result is obtained, characterized in that the extent of beam deflection is calibrated on the display unit according to the dimenson of the independent factor representing at least one technological parameter in one of the directions and according to the dimension of the independent factor representing at least one further technolgoical parameter in the other - e.g. vertical - direction, the brightness and/or colour in the image spot of the video screen determined by the deflection according to the given momentary value are controlled according to the value of the dependent factor appearing at a concrete momentary value of above factors, and level lines identi- cally oriented with the two deflection directions are superposed mechanically or electronically on the displayed image, and by changing the position of the level lines independently from each other the lower and upper limit values in both directions are determined, within which at any possible combination of the independent factors the brightness and/or colour of the image spot will remain within the permissible tolerance range at any point of the limited area.
