Application
Widely used in electronics cleanrooms, SMT and PCB workshops, semiconductor factories, optical and display workshops, new energy workshops, electronic assembly and repair workstations and other ESD-controlled areas.
Features
• Single Station Real-time Monitoring For one operator, continuously detects wrist strap circuit continuity and ground connection status.
• Audible & Visual Alarm Prompt Green LED for normal status; red LED plus buzzer alarm activates instantly once circuit abnormality is detected.
• Adjustable Alarm Threshold Default resistance range:1.068MΩ ~2.0MΩ (±5%). Threshold can be customized according to factory ESD control requirements.
• Strong Anti-interference Performance Built-in anti-EMI circuit, effectively reduces false alarms caused by electromagnetic noise from surrounding production equipment.
• Microchip Control & Plug-and-Play Microprocessor design, no complex calibration required after installation. Ready to operate after connecting power and ground wire.
• Metal Mountable Housing Grey metal casing with mounting lugs, can be fixed on workbench or wall. Equipped with DC6V power adapter and ground alligator clip.
• Fast Alarm Response Response time ≤0.1s, quickly alerts operators to abnormal grounding condition.
Usage Instructions
- Mount the 209-1 monitor on ESD workbench, connect DC6V power adapter and reliable earth ground via alligator clip.
- Plug one ESD wrist strap into the input port of monitor.
- Operator must wear wrist strap tightly against skin. Green light stays on when grounding circuit is normal.
- Red light and buzzer alarm will activate if wrist strap falls off, wire broken or poor skin contact. Stop work and troubleshoot immediately.
- Regular function test: disconnect wrist strap to verify alarm works well for daily ESD audit.
