Precautions for anti-static tester
1. When the upper limit of anti-static shoes is set to 1GΩ, the surface of the foot pedal should be kept clean, and the test may be inaccurate when the relative humidity of the environment exceeds 50%
2. Keep the test finger dry. After long-term use, oil stains may cause short circuit between the inner and outer conductors of the test key. Clean the test key regularly with alcohol.
3. The test meter must be properly grounded before turning on the power to work normally
4. The internal chip will be damaged if the test meter is not grounded
5. When cleaning the floor, avoid leaving water stains on or around the pedals. The back of the pedals must be kept dry
6. Climate or season changes cause the air humidity to change, and the moisture absorbed by the anti-static shoes made of hydrophilic materials causes the test to be unstable. This is not a problem with the tester, but a change in the resistance of the anti-static shoes.
7. The resistance of cheap insulated shoes on the market is only 108~109 ohms, so it is possible to be within the qualified range of anti-static during testing.
8. Ordinary footwear may be within the qualified range of anti-static due to its absorption of water
