Anti-static wrist strap detector operation steps

                                              Anti-static wrist strap detector operation steps

Anti-static wrist strap is a device that releases the body's electrostatic charge. It is usually divided into a corded wrist strap, a cordless wrist strap and a smart anti-static wrist strap. The structure is divided into a single-loop wrist strap and a double-circuit wrist strap. Activity snap button, spring cord. Protective resistor and plug or collet. The inner layer of the elastic band is woven with an antistatic yarn, and the outer layer is woven with ordinary yarn. It is a new type of device that regulates the function of the human body.

 The anti-static cordless wrist strap pushes the human body electrostatic ions into the static electricity collection area by the characteristics of static electricity pushing from high potential, and then [charge induction principle] will make the front and back surfaces of the conductive plate have "equal isotropic charges" respectively. Because the ion exchanger (with its low free energy characteristic) is built in the zone, it can easily provide the isotropic charge of the introduced electrostatic ions to neutralize, so that the effect of static discharge can be achieved, and another one is provided outside the product. Only the screw is connected to the inner conductor loop. If necessary, the screw can be in contact with the ground, so that the static electricity can be released.

The corded wrist strap consists of an anti-static elastic band, a spring rubber cord, a protective resistor, and a plug or collet. The elastic band is woven with a special process of textile yarn. The inner layer is made of anti-static material. When the wristband is in direct contact with the wrist skin, and the ground wire is connected to the earth, it can be used for maximum effect. The product can quickly and safely remove static electricity generated by the human body in 1/10 second. The corded grounding wrist strap is the most basic, economical and most commonly used in anti-static wristbands.

 The antistatic wrist strap releases static electricity accumulated on the human body to prevent high voltage static electricity from penetrating the component when operating or touching electronic components. Usually used in electronics, medicine, aerospace, precision machinery, etc.

The wrist strap tester is a complete body grounding system. When the wrist strap is still on the operator's wristband, the connector will be checked for connectivity. Red LED and audible alarm connection error (Fail HI), red light and sound alarm display low resistance (Fail LO). The green LED indicates properly grounded (OK). The factory setting test parameters to 800K-10M, according to the requirements of support Adjustment. The instrument is equipped with a 9V battery to detect a continuous path between the operator, the wrist strap and the ground wire. With a test voltage of 9v DC, the instrument is designed to be flawless and harmless to the human body.

     Steps:

     1. When wearing the wrist strap, insert the banana plug into the connection.

     2. Tap the metal test button and the instrument can be used.

     3. The green "OK" LED shows that the wrist strap and grounding wire are working properly.

     4. If the red light "FAIL LO" or the yellow light "FAIL HI" LED and alarm sound, the operator should immediately check the wrist.

     (1) Electrostatic tester: a measure the static electricity of the product or a certain position. b measure the static elimination performance of the static eliminator

    (2) Wrist strap tester: Measure whether the wrist strap is effective.

    (3) Wrist strap online monitor: Monitor the wrist strap for damage and wear at any time.

    (4) Human body comprehensive tester: It can be used to measure whether wrist straps and anti-static shoes are effective, and can also measure the comprehensive resistance of the human body.

    (5) Surface resistance tester: used to measure the impedance or resistance of the surface of all conductive, antistatic and electrostatic discharge products.

    (6) System monitoring alarm device: It is possible to monitor whether the working water ground wire is in good contact with the earth at any time.
