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
• Two Independent Monitoring Channels Two separate circuits for two operators. Each channel has independent LED indicator, no cross interference.
• Separate Audible & Visual Alarm for Each Channel Green LED for normal condition; red LED plus buzzer alarm activates within 0.1 second when abnormality occurs. Operators can quickly identify which channel is faulty.
• Adjustable Alarm Resistance Threshold Default resistance range: 1.068MΩ ~ 2.0MΩ (±5%). Threshold can be customized according to factory ESD control specification.
• Anti-EMI Interference Circuit Built-in electromagnetic interference suppression circuit, effectively prevents false alarms caused by motors, soldering stations and other workshop equipment.
• Intelligent Microchip Control, Plug & Play No complicated calibration required after installation. Just connect power and ground wire to start working.
• Sturdy Metal Housing with Mounting Tabs Grey metal casing, durable and easy to mount on workbench or wall. Standard accessories include DC6V power adapter and ground alligator clip.
• Short Alarm Response Time Response time ≤0.1s, fast warning for operators to stop production and troubleshoot grounding issues.
Usage Instructions
- Fix the 209-II monitor on ESD workbench. Connect DC6V power adapter and connect ground clip to reliable earth ground.
- Insert two ESD wrist straps into Channel 1 and Channel 2 ports respectively.
- Two operators wear wrist straps tightly against skin. The corresponding green LED lights up when grounding loop is normal.
- If one wrist strap falls off, wire breaks or skin contact is poor, that channel will light red LED and sound buzzer. Stop operation and check immediately.
- Perform regular function test: unplug each wrist strap one by one to verify alarm function for daily ESD audit.
