Exhibit №2
Results of independent metrological testing of programs for calculation of the heart rate variability parameters

7.2.Non-linearity of gain-frequency descriptions
We will remind that non-linearity of AFC (amplitude-frequency characteristic) is calculated as a relation of difference of maximal and minimum values of the calculated powers of spectrum in relation to the mean value of the calculated power (0 is absolute linearness)

Notes:
1. By a grey color is selected tests with the extremely low set powers which actual for the special objects of researches (look the chapter);
2 no data - the program did not execute calculations with this selection;
3.zero - in the results of test program reported about zero-mistake.
