Friction voltage test
1. Test standard: IEC61340-2-2, ESDA ADV11.2
2. Test method: A. Ensure that the two tested objects and the surrounding environment are not charged before the test; B. The friction process will not be affected by other external objects; C. Take tools (tweezers, gloves, etc.) and the workbench will not affect the test The static electricity level; D, static electricity can be maintained for a certain period of time, in order to be able to read the data.
Typical test
1. Object repeated friction test: A. The established speed, direction, pressure and friction time; B. The material that may actually exist is used as the test material;
2. Object sliding friction test: A. Usually static electricity and static voltage are tested; B. Different sliding conditions (such as front sliding and back sliding) are tested; C, actual, especially the longer sliding distance; D, fixed Slip angle
3. Rotational friction of thin film materials
Precautions for using measurement
1. The instrument must be calibrated and reset to zero
2. The correct distance between the electrode and the measuring surface
Three, correct grounding
4. The human body is grounded and discharged when the operator is in use
5. The surrounding environment of the measured object, the measurement activity will affect the measurement result.
