温度和湿度:固体绝缘材料的绝缘电阻率随温度和湿度的升高而降低,特别是体积电阻率随温度改变而变化非常大。


When measuring volume resistance, set the test button to the Rv side, and when measuring surface resistance, set the test button to the Rs side,

GB/T 22042-2008 Test Method for Surface Resistivity of Clothing Antistatic Performance

The unprotected electrode, protected electrode, and protected electrode should be coaxial and confirm that there is no short circuit between the electrodes.

GB 4655-2003 Safety Regulations for Static Electricity in the Rubber Industry

Do not arbitrarily change the measured voltage during the testing process.

Therefore, the determination should be strictly carried out in accordance with the specified sample processing requirements and the environmental conditions for testing.

Gradually shift from low gear to high gear during measurement.

It is prohibited to short circuit both ends of "RX" to avoid the impact of high current on the micro current amplifier

GB 50515-2010 Design Code for Conducting (Anti) Static Electricity Ground

When measuring high resistance, a shielding box should be used to shield the measured object.

GB/T 15738-2008 Test Method for Electrical Resistivity of Conductive and Antistatic Fiber Reinforced Plastics

GB/T 1692-2008 Vulcanized Rubber - Determination of Insulation Resistance

GB/T 22043-2008 Antistatic Performance of Clothing - Test Method for Resistance (Vertical Resistance) of Materials



Zero should be set when there is an open circuit at both ends of "Rx". Generally, there is no need to zero again during the testing process after one zero adjustment.

Temperature and humidity: The insulation resistivity of solid insulation materials decreases with the increase of temperature and humidity, especially the volume resistivity changes greatly with temperature.

GB 13348-2009 Safety Regulations for Static Electricity of Liquid Petroleum Products

ASTM D257-99 "Test Method for DC Resistance or Conductivity of Insulating Materials"

Therefore, electric porcelain materials not only need to measure the volume resistivity at room temperature, but also need to measure the volume resistivity at high temperature to evaluate their insulation performance.

GB/T 1410-2006 "Test Methods for Volume and Surface Resistivity of Solid Insulating Materials"

After connecting the power supply, fingers should not touch the metal parts of the high-voltage wire.

GB/T 1410-2006 Test Methods for Volume and Surface Resistivity of Solid Insulating Materials

Do not touch the micro current testing terminal during the testing process.

GB 12014 Anti static Work Clothes

So, surface resistivity is not a parameter that characterizes the characteristics of the material itself, but a parameter related to the surface pollution characteristics of the material. When the surface resistance is high, it often changes in an irregular manner over time. The measurement of surface resistance usually requires an electrochemical time of 1 minute.

GB 50611-2010 Code for Antistatic Design of Electronic Engineering

GB1672-8 Determination of Volume Resistivity of Liquid Plasticizers

GB 26539-2011 Anti static Ceramic Tile

(For example, GBT 1692-2008 specifies in the standard for measuring the insulation resistivity of vulcanized rubber that it is required to be measured at a voltage of 500V, so the voltage must be increased to 500V)

Due to the high conductivity of water, as the humidity increases, the surface resistivity and the volume resistivity of ceramic materials with open pores sharply decrease.

Connect the test cable and connect the host to the shielding box. Set the range to 104 and turn on the power switch button on the rear panel of the host. Adjust the voltage button from the rear panel of the instrument to the required measurement voltage.

The current resistance range button gradually shifts from low to high gear, staying for 1-2 seconds each time to observe the displayed number. When the measured resistance is greater than the instrument's measurement range, the resistance meter displays "1". At this time, the instrument should continue to be moved to a higher range ***ition. When the measuring instrument displays a value, it should stop and measure the resistance after 1 minute of electrification. The current number multiplied by the grade is the measured resistance.

GB 4385-1995 Technical Requirements for Antistatic and Conductive Shoes

After the test is completed, first set the range to (104), then set the measurement voltage to 10V, and then turn off the power after turning the test button to the ce***al ***ition. Then proceed to the next test.

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。

(比如:GBT 1692-2008 硫化橡胶 绝缘电阻率的测定 标准中注明要求在500V电压进行测定,那么电压就要升到500V)
由于水的电导大,随着湿度增大,表面电阻率和有开口孔隙的电瓷材料的体积电阻率急剧下降。
接好测试线,将测试线将主机与屏蔽箱连接好。量程置于104档,打开主机后面板电源开关按钮。从仪器后面板调电压按钮到所要求的测量电压。

电流电阻量程按钮从低档位逐渐拨高档,每拨一次停留1-2秒观察显示数字,当被测电阻大于仪器测量量程时,电阻表显示“1”,此时应继续将仪器拨到量程更高的位置。测量仪器有显示值时应停下,在1min的电化时间后测量电阻,当前的数字乘以档次即是被测电阻。

测试完毕先将量程拨至(104)档,然后将测量电压拨至10V档,较后将测试按钮拨到中央位置后关闭电源。然后进行下一次测试。
