Product friction voltage test method:
A. Ensure that the two tested objects and the surrounding environment are not charged before the test;
B. The friction process is not affected by other external objects;
C. Take tools (tweezers, gloves, etc.) and the workbench will not affect the static electricity level of the test;
D. Static electricity can be maintained for a certain period of time so that data can be read. The precautions for the friction voltage test are as follows:
1. The instrument must be correctly calibrated and reset to zero;
2. The correct distance between the electrode and the measuring surface;
3. Correct grounding;
4. The human body is grounded and discharged when the operator uses it;
5. The surrounding environment of the measured object, the measurement activity will affect the measurement result;
6. Measure 5 times and take the average value.
Introduce the instrument with the advantages of high precision and large measuring range for measuring friction voltage
EFM-022 Electrostatic Field Tester: The EFM-022 tester uses a rotating blade probe to measure the field strength. The rotating blade design is more sensitive than the vibration type and is more suitable for continuous long-term measurement. The instrument shell is made of EMV plastic, which effectively shields signal interference. The measured value is displayed on the LCD screen, the first line of the screen displays the selected distance, the first line displays the measured value, the palm-sized compact design adopts an easy-to-see large LCD display, and the maximum is ±160kV (measurement distance: 20CM, for simple Charge measurement of static electricity, investigation of specific charge level of static electricity generating place, static electricity countermeasure plan, effect measurement, maintenance management, etc.
