Quality assurance of double circuit wrist strap
The dual-circuit wrist strap needs to be tested before use, mainly to make our use more secure. So how do you need to measure?
Everyone should know that the use of double-circuit wrist straps is related to the quality of the product. At work, the copper wires in the double-circuit wrist straps are not easily bent and will not be allowed inside the wires. The metal fiber is broken and does not cause the failure of the anti-static function of the wrist strap.
In fact, measuring the quality of the double-circuit wrist strap is also a special instrument. We can put the double-loop wrist strap that needs to be used on the test instrument, and prepare a small word or Phillips screwdriver and a Rope wrist strap. Ground the monitor and plug it in. Then plug in the double-circuit wrist strap and reconfirm the wrist strap monitoring point that is not working properly. Put the small screwdriver into the small hole on the front of the equipment corresponding to the monitoring point of the double-circuit wristband that is not working properly. You can also fine-tune the internal potentiometer counterclockwise or fine-tune clockwise.
The double-circuit wrist strap will pass the strict suspension weight bending test before leaving the factory. The product process, quality and process are strictly monitored to ensure that the product can meet the specified number of bends and the service life is 1-2 years. There are some good products, almost no damage caused by normal wear and tear, to provide customers with lifetime quality assurance.
