**Fabric Frictional Charge Tester – User Guide and Precautions**
The following instructions and safety precautions for the fabric frictional charge tester are provided by Standard Group (Hong Kong) Co., Ltd., a well-known brand both domestically and internationally. As many of their products are imported, they have surpassed numerous globally recognized brands.
**Step-by-Step Instructions:**
1. Insert the power plug of the roller friction machine into a grounded power socket.
2. Turn on the power switch of the roller friction machine and set the test duration to 15 minutes.
3. Place the sample into the roller friction machine. The machine will stop automatically after 15 minutes.
4. Connect one end of the specialized cable from the electrostatic potentiometer to the input port of the charge tester, and the other end to the outer cylinder socket of the Faraday cage.
5. Power on the charge tester by turning the switch to the “1†position.
6. Press the “Clear†button to reset the charge meter to zero.
7. After the roller friction machine stops, use an insulating rod or wear gloves with an insulation resistance of at least 10¹² Ω to remove the sample. Immediately place it inside the Faraday cage. Ensure that you stay more than 300 mm away from any conductive objects, such as your body or metal surfaces.
8. Read the electrostatic charge value in microcoulombs (μC).
9. Repeat the test five times. Allow a 10-minute interval between each test. Before each test, immerse the sample and drum in de-energized water.
10. Calculate the average of the five readings. If the charge is less than 0.6 μC, it meets the requirements of Class B under GB12014-2009 for anti-static clothing.
11. After completing the test, turn off the power switch and unplug the machine.
**Important Notes:**
1. The Faraday cage must be properly grounded for accurate results.
2. Always clear the charge tester before each measurement.
3. Ensure the object being tested is disconnected from any power source during testing.
4. Turn on the power switch and allow the machine to warm up for 15 minutes before starting the test.
5. Make sure the inner lining of the overalls is turned outward, and remove cold-weather clothing after testing the lining.
6. Place the roller friction machine on a stable surface to avoid noise and instability.
7. Do not place sharp metal objects like pins or coins inside the drum, as they may damage the inner lining.
8. Conduct tests in an environment with a temperature of (20 ± 5)°C and a relative humidity of 40%.
