Analysis of conversion equations and equations of errors of the generalized block diagram of the iteratively integrating measuring converter which uses iterative integrating conversion method was performed. An analysis for the simplest case of combinations of input and output values, namely when all input values X, Z1 and Z2, as well as the output value Y are constant values was carry out. The results of the analysis can easily be extended to all the other cases. Here considers situation when the additive errors of all blocks change continuously in time. For ease of analysis the curve of change of the considered error by straight line segments within each conversion cycle was approximated. We can formulate the requirements for the errors of blocks of the measuring converter. The results of the analysis of the generalized block diagram of the measuring transducer can be used to create specific outlines of iteratively integrating converters, in particular, the requirements on the errors of their blocks can be formulated.
