摘要

为了克服热电材料电阻率测量精度低的问题，以LabVIEW为软件平台，设计并制备数据采集及控制电路，构建了热电材料电阻率测量系统.测量系统具有测量精度高、电阻率测量范围大、界面友好、显示信息丰富等特点，实现了手动测量与自动测量，并具有可控频率的电流自动换向功能，有利于提高测量精度.经实验验证，测量系统的相对误差在-0.25%~+0.25%内，对于热电材料的测量这是一个有价值的测量系统.

Abstract

A resistivity measuring system of thermoelectric material was designed with the LabVIEW as software and the circuit of control and data acquisition as hardware

in order to overcome the problem of low resistivity measurement accuracy. The measurement system has the characteristics of high measuring accuracy

wide measurement range

friendly interface and rich display information. It has an ability to finish manual measurement or automatic measurement. At the same time

it can change the direction of current with controllable frequency in order to improve the measurement accuracy. Experiments show that the relative error within -0.25%~+0.25%. It is a valuable measurement system for property measurement of thermoelectric material.
