| Abstract: | Based on the problem which the change of electrical conductivity of alloy material causes the performance change as the temperature changes,we designed an electrical conductivity measurement system.The system could measure the conductivity from room temperature to cryogenic area through simple operation.At the same time,it had some functions to display,save,print and transport the data.This system could eliminate measuring error of conductivity caused by temperature change with the temperature calibration m... |
