Abstract :
In this report the multimeter frequency properties, in supposition that sensor transformation coefficient in given frequency band is fixed, are considered. The aim of report is working out methodic for algorithm comparison. Multimeter has the mathematical description as systems of linearized equations relatively intermediate variables. The matrix of a system is written down through trigonometrical expression, which arguments are intervals between sensors, phase spacing is connected to frequency. Therefore frequency change is simulated with the help of the description of change of phase spacing interval between sensors in a matrix of a system. The matrix of a system determines as error primary sensor is transformed to error of intermediate variables.
