Anti-static bracelet tester digital display 498A
Function: For the function of the electrostatic wrist strap, the 498 can quickly and easily check the following items:
1. The connection between the electrostatic wrist strap and the grounding wire
2. Contact impedance between electrostatic wrist strap and skin
3. Connection with grounding tools such as electrostatic pads and mats
Features:
Various grounding systems can be checked quickly and easily from any location. Eliminate product damage caused by static electricity and ensure the safety of every employee. The tester has a wide range of applications and can be connected to all wired wrist straps that meet ESD standards. Its interface is a banana jack. Many wrist straps can be used well together, with the advantages of tight contacts, small contact resistance, good connectivity, long life, and good oxidation resistance.

1. This tester is a special wrist strap and hamstring strap tester, which is mainly used to test whether the wrist strap and hamstring strap are good or bad.
2. Stable performance, wide operating temperature range, suitable for a variety of working environments, the selected circuit layout is reasonable, the circuit is stable, the external interference is small, and the adjustment is convenient, which is very good for this product.
3. The external port of the tester is connected to the wrist strap banana plug, the wrist ring is in close contact with the metal snap button, and the button is pressed. When the external line loop rises to more than 10MQ or less than 800KQ due to various factors, the tester monitoring circuit will automatically emit a sound Light alarm to remind user to pay attention (wrist strap damaged).
4. This tester has sensitivity, independent adjustment ports, it has been adjusted before leaving the factory, please do not change its application range without permission, if there is a problem with self-adjustment, it will not bear the loss caused by it, if you have special requirements, please contact the supplier.
5. The tester is connected with a DC 9V battery. The allowable range of this tester is 800K≤R≤10MK5%, and there are special specifications that will be notified separately.
6. This tester is widely used, and can be connected to all wired wrist straps that meet ESD standards, and its interface is a banana jack.
