This paper investigates the features of using modified Hamming codes, which are also known as Hsiao codes. Self-checking digital devices are proposed to be implemented with calculations testing using two diagnostic signs. These signs indicate that the functions (there are functions that describe check bits) belong to the class of self-dual Boolean functions and also belong to the codewords of Hsiao codes (these are codes with an odd column of weights). The authors have established that all check
