The meridian-acupoint has response function and effect function. As a direct reflection between acupoint and diseased area, the response function is the foundation of the effect function, and skin resistance of acupoint is usually used as an objective indice for research of meridian-acupoint response. Among the skin resistance-based researches on specificity of meridian-acupoint reaction, the selection of instrument is a key point. At present the main measurement instruments for meridian-acupoint resistance include dual-electrode device and four-electrode device. After analyzing the characteristics and inter-ference factors of different types of measurement instruments for meridian-acupoint resistance, dual-electrode device is suitable for qualitative analysis, for its control of interference factors needs to improve. The four-electrode device is good at quantitative research, for it is easier to control interference factors. Yet, there is more for research department to do to improve the instrument design by modern scientific technique in order to meet need for research.
经络穴位具有反应功能和效应功能。作为穴位与病变部位之间的直接反映，反应功能是效应功能的基础，而穴位皮肤电阻通常被用作经络穴位反应研究的客观指标。在基于皮肤电阻的经络穴位反应特异性研究中，仪器的选择是关键。目前经络穴位电阻的主要测量仪器包括双电极装置和四电极装置。在分析了不同类型经络穴位电阻测量仪器的特点和干扰因素后，双电极装置适合定性分析，因其对干扰因素的控制有待改进。四电极装置擅长定量研究，因为它更容易控制干扰因素。然而，研究部门仍需通过现代科学技术改进仪器设计，以满足研究需求。
