The Systemic Error of the Difference Voltage Method in the Calibration of Heavy DC Sensors |

| Abstract: | he systemic error of the difference voltage method in the calibration of heavy DC sen-sors is discussed.The formulas for the svstemic error are derived for both the current-volt-age sensor and current-current sensor.The principal part of systemic error and the definitionof methodical error are discussed.the rules for the proper selection of parameters of the e-quipments used for the calibrating system are given. |
