Suitable for rubber, plastic, film, and powder, liquid, and solid and paste the shape of various insulating material volume and surface resistance values. In addition to the instrument can measure resistance, but also directly measure the weak current.

一、测量技术 ：

Measurement technique:

a.通常，绝缘材料用于电气系统的各部件相互绝缘和对地绝缘，固体绝缘材料还起机械支撑作用。一般希望材料有尽可能高的绝缘电阻，并具有合适的机械、化学和耐热性能。

A. is usually used in the insulation material for each part of the electrical system to be insulated from each other and to the ground. Generally, it is hoped that the insulation resistance of the material is as high as possible, and it is suitable for the mechanical, chemical and heat resistance.

b.绝缘材料的电阻率一般都很高，也就是传导电流很小。如果不注意外界因素的干扰和漏电流的影响，测量结果就会发生很大的误差。同时绝缘材料本身的吸湿性和环境条件的变化对测量结果也有很大影响。

B. insulation materials are generally very high, which is a very small conduction current. If we do not pay attention to the influence of external factors, the measurement results will have great errors. At the same time, the change of the moisture absorption and environmental conditions of the insulation material also has a great influence on the measurement results.

c.影响体积电阻率和表面电阻率测试的主要因素是温度和湿度、电场强度、充电时间及残余电荷等。体积电阻率可作为选择绝缘材料的一个参数，电阻率随温度和湿度的变化而显著变化。体积电阻率的测量常常用来检查绝缘材料是否均匀，或者用来检测那些能影响材料质量而又不能用其他方法检测到的导电杂质。

The main factors that affect the volume resistivity and surface resistivity of C. are temperature and humidity, electric field intensity, charging time and residual charge. Volume resistivity can be used as a parameter to selec the insulation material, the resistivity changes with temperature and humidity. Volume resistivity measurements are often used to check whether the insulation material is uniform, or to detect the conductive impurities that can affect the quality of the material, and can not be detected by other means.

d.由于体积电阻总是要被或多或少地包括到表面电阻的测试中去，因此只能近似地测量表面电阻，测得的表面电阻值主要反映被测试样表面污染的程度。所以，表面电阻率不是表征材料本身特性的参数，而是一个有关材料表面污染特性的参数。当表面电阻较高时，它常随时间以不规则的方式变化。测量表面电阻通常都规定1min的电化时间。

D. because the volume resistance is always more or less to the surface resistance of the test, it can only approximate the surface resistance, measured surface resistance values are mainly reflected in the degree of surface contamination of the test sample. Therefore, the surface resistivity is not a parameter to characterize the material itself, but a parameter for the surface contamination of the material. When the surface resistance is high, it often changes with time. Measurement of surface resistance is usually required for 1min of the electrochemical time.
