Low (red) R<900KΩ
Good (green) 900KΩ ≤ R ≤ 10MΩ
High (red) R>10MΩ no
External dimensions: 80 (W)x40 (H)x117 (D) mm
Power supply: DC 9V battery
Hold the tester's squid clip on the wrist strap grounding clamp to be tested (the cordless wrist strap needs to clamp the top screw), and press the tester intermediate test disc with the hand with the wrist strap. If the grounding system is normal, the green “GOOD” light will Lights up and makes a sound, indicating that the wrist strap can be used normally. If the “HIGH” or “LOW” light on both sides is on, it indicates that the wrist strap cannot be used normally.
1. The connection of the wrist strap to the grounding wire.
2. Contact impedance between the wrist strap and the skin.
3. Connection with grounding tools such as anti-static boards and mats.
It can quickly and easily check various grounding systems at any location to avoid product damage caused by static electricity and to ensure the safety of workers.
The hand strap detector is a detection instrument that uses a fixed impedance range and LED display detection results. It has the characteristics of accurate detection, rapid and easy to use. It is mainly used to test whether the performance of the hand strap is good and conforms to the standard. Requirements to ensure that the hand strap is used when it is effective, so that it can achieve true electrostatic protection.
Remark: After about 50,000 operations, when the green "GOOD" light still lights up, but no sound is heard, it means that the battery needs to be replaced.
