First, the main purpose of fabric friction electric charge tester
The fabric triboelectric charge tester is mainly used to test the charged charge of the antistatic clothing. The device is mainly composed of a Faraday cup, an electrostatic potentiometer and a drum friction machine. Note: Static potentiometers are also commonly referred to as electrostatic meters. They are mainly used to display the charge of textiles such as anti-static clothing and anti-static fabrics.

Second, the fabric frictional charge tester test principle
Put the antistatic clothing into the roller friction machine, and put the antistatic clothing rubbed by the roller friction machine for 15 minutes into the Faraday cup, and measure the charged charge of the antistatic clothing by the electrostatic potentiometer.
Third, the fabric frictional charge charge tester steps
1. Insert the roller friction machine power cord plug into the power outlet (the ground wire must be connected).
2. Open the roller friction machine power switch and set the test time to 15?min.
3. Put the sample in the roller friction machine to run. After 15 minutes, the roller friction will stop automatically.
4. Connect one end of the dedicated connector of the electrostatic potentiometer to the input port of the charge tester, and connect the other end to the socket on the outer tube of the Faraday's cylinder.
5. Turn on the power of the charge meter - turn the power switch up to the "1" position.
6. Press the "Clear" button to make the charge meter display zero.
7. After the roller friction machine is automatically stopped, take out the sample directly from the roller friction machine with an insulating rod (or wear the insulation resistance of the insulating glove and remove it directly at 10?12Ω) and immediately put it into the Faraday cage. Attention should be paid at this time. The distance between the sample and the human body, metal, etc. is more than 300 mm.
8. Read the reading of the static electricity tester, the unit is micro bank (μC).
9, repeat the test 5 times. Between each test and test, separated by 10 minutes, before each test, the sample and drum lining standard cloth should be dealt with.
10, take the average of 5 times, if the charge is less than 0.6μC, then meet the national standard GB12014-2009 "anti-static clothing" Class B requirements.
11. After the test is completed, turn off the power switch and unplug the power plug.
Fourth, pay attention to matters
1. The Faraday cylinder barrel of this system should be reliably grounded.
2. Please reset the charge measuring device before each measurement.
3, measured objects must be out of power.
4. Before the test, please turn on the power switch to warm up the machine for 15 minutes.
5. The lining work clothes should be turned outwards, and the cold clothes should be tested after removing the liners and linings.
6. The roller friction machine should be placed on a stable table so as to prevent the operation from swinging and generating large noise.
7. Do not put pins, coins, and other sharp metal objects into the drum to avoid damaging the liner.
8. The environmental conditions for the anti-static overalls test are temperature (20 ± 5) °C and relative humidity of 40%.
