AS-311 Wrist Strap FAQ and support
What is the AS-311, and what is it primarily used for?
It is a corded antistatic wrist strap that uses a wrist band and 3 m grounding lead to discharge body static gradually to a verified grounding point.
Which users or work situations is the AS-311 suitable for?
The AS-311 is suitable for electronic production lines, PCB assembly, computer repair, and personnel handling electrostatic-sensitive components. Follow the product manual, site conditions, and operating procedures.
What are the features and benefits of the AS-311's 3 m grounding cord and approximately 1 MΩ lead resistance?
The 3 m cord provides a broad working range, while approximately 1 MΩ resistance limits discharge current so static dissipates in a controlled manner. Use it with a correct verified grounding arrangement.
What are the features and benefits of the AS-311's fixed elastic wrist band?
The elastic fixed band keeps the conductive material in continuous contact with the skin to maintain the grounding path. This design improves operating consistency.
What is the correct basic operating method for the AS-311?
Wear the band on a bare wrist and adjust it for full contact. Connect the grounding end to a verified ESD ground before touching sensitive components.
What important specifications or compatibility limitations apply to the AS-311?
Wrist-band resistance is approximately 10³-10⁵ Ω, grounding-cord resistance is 10⁶ Ω, the band is fixed, and the cord is 3 m long.
What safety precautions apply when using the AS-311?
Connect only to an approved ESD ground. Never clip it to a mains live conductor, unknown metal, or equipment without verified grounding.
How should the AS-311 be cleaned and maintained after use?
Regularly inspect wrist-band conductivity, connectors, and the cable for breaks. Clean the band according to frequency of use and perform periodic ESD tests.
How should I choose between the AS-311 and similar tools?
A corded wrist strap provides stable grounding at a fixed workstation. A wireless strap does not replace a formal grounding arrangement and ESD workbench system.
Which points should be confirmed before purchasing the AS-311?
Confirm the workstation grounding specification, cable length, wrist-band size, and connector type, and establish a periodic testing and replacement program.
