FR2201 Wrist strap tester

Wrist Strap Tester – Description

A Wrist Strap Tester is a compact device designed to verify the functionality of anti-static wrist straps, ensuring they provide proper electrostatic discharge (ESD) protection in static-sensitive environments. It checks that the wrist strap and its grounding cord are working correctly, helping to prevent damage to sensitive electronic components due to static buildup. Commonly used in electronics manufacturing, repair facilities, and cleanrooms, wrist strap testers are essential tools for ESD compliance programs.

Key Features

• Pass/Fail Indicator: Provides a clear visual (LED) or audible (buzzer) indication of whether the wrist strap is functioning within acceptable resistance limits

• Quick testing: Allows for rapid daily checks—users simply plug in and press a button or touch a contact plate

• Adjustable resistance thresholds: Some testers let you set high and low resistance limits (e.g., 750KΩ to 35MΩ) according to industry standards

• Battery or wall-powered: Available in portable battery-powered units or fixed wall-mounted versions

• Touch plate or button: Tests are usually initiated by touching a metal plate or pressing a button while wearing the wrist strap

• Optional logging features: Some advanced models include data logging or badge access for audit trails and compliance monitoring

• Dual wrist strap testing: Certain testers can check dual-wire wrist straps, offering more robust ESD protection monitoring

• Compact and durable: Built to withstand regular use in busy environments

Common Applications

• Electronics manufacturing: Ensures that workers’ wrist straps are properly grounded before handling sensitive components

• Quality control: Used as part of ESD control programs in compliance with ANSI/ESD S20.20 and IEC standards

• Cleanrooms: Prevents contamination and damage to products by ensuring static safety

• Service centers and labs: Provides an easy method for technicians to check their wrist straps before working

• Educational and training labs: Used in classrooms or training facilities to teach ESD safety procedures

Benefits

• Protects sensitive electronics: Ensures ESD wrist straps are functional and safe, helping to prevent costly damage or failure of components

• Supports compliance: Helps meet industry ESD standards and maintain audit readiness

• Easy to use: Simple design allows for quick daily checks with minimal disruption

• Increases safety awareness: Reinforces ESD control protocols by encouraging regular testing of protective equipment

• Reduces downtime and defects: Minimizes the risk of ESD-related damage, ensuring more reliable production and service work
