Precautions for the use of surface resistance tester
Runfengyuan shares what is a surface resistance tester and precautions for use: a surface resistance tester is an instrument for testing the surface resistance of an object, and is mostly used in microelectronics, medicine, aerospace, precision machinery and other fields. Surface resistance tester (English: ESD Resistance tester).
Surface resistance testers are widely used in microelectronics, medicine, aerospace, precision machinery and other fields. Note: It is used to quantitatively measure the surface resistance or system resistance of all conductive, antistatic and electrostatic discharge materials. It is simple to use and easy to carry. Just place it on the surface of the object to be tested and press the red button, the indicator lights on the instrument range from 103 to 1012Ω, and one of the LED lights will light up according to the test value. Note: This tester cannot measure objects whose surface resistance exceeds 1012Ω.
Precautions for the use of surface resistance tester:
1. The connection between the electrostatic wrist strap and the grounding wire; 2. The contact impedance between the electrostatic wrist strap and the skin; 3. The connection with the anti-static connecting plate, mat and other grounding tools. 4. After about 50,000 operations, when the green "GOOD" light is still on, but no sound is heard, it means that the battery needs to be replaced.
Application 1. Ensure the safety of each employee; 2. Eliminate product damage caused by static electricity. 3. The anti-static wristband tester can easily detect the performance of various types of anti-static wristbands. If the resistance value is not within the standard range or the battery is too low, it will automatically alarm, and the red light will be on and accompanied by an alarm; Automatic alarm when pressed; small size, light weight, easy to use, intuitive detection.
