Abstract :
A method of analyzing and calculating the systemic error of the voltage difference method in the calibration for heavy DC sensors is developed. For both current-voltage sensor and current-current sensor, the expressions for their systematic error are derived. The definitions of the methodical error are discussed. The rules for the reasonable selection of parameters of the equipment used for the calibration system are given.
