Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si This product features an industrial-grade chip with strong anti-electromagnetic interference and low-temperature resistance. There is a self-test function to check that the car itself has no quality problems. The detection effect is more intuitive, through the transformation of the circular arrangement of lights, distinguish brushless controller is 120 degrees or 60 degrees phase angle and the fault of the brushless controller. Quickly detect the brushless motor, motor hall phase sequence, controller, and turn brake. Suitable for 24V/36V/48V/60V/72V two-wheeled or three-wheeled electro mobiles. Specifications: Name: Electromobile Detector; Battery: 1 x 9V battery (not included) Material: plastics Color: White Features: 1. Built-in industrial-grade chip, anti-static, strong anti-electromagnetic interference, low-temperature resistance. 2. Using one switch to turn on/off, quickly detect safety and convenience. 3. There is a self-test function to check that the car itself has no quality problems. 4. The detection effect is more intuitive, through the transformation of the circular arrangement of lights, distinguish brushless controller is 120 degrees or 60 degrees phase angle and the fault of the brushless controller. 5. Alligator clips bite strong and clamp tight, not easy to fall off. 6. Wire cores all use pure copper wire, and thickened wire to fine conductivity. 7. Premium quality rubber sleeve, isolation insulation, prevents short circuit. 8. The battery is easy to remove, open the battery compartment and replace the battery. 9. Quick detection of motor and controller phase angle is 60 degrees or 120 degrees. 10. Quickly detect the brushless motor, motor hall phase sequence, controller, and turn brake. 11. Brushless motor and controller fast wiring (36 kinds of connection). 12. Suitable for 24V/36V/48V/60V/72V two-wheeled or three-wheeled electro mobiles. Package Contents: 1 x Detector Only the above package content, other products are not included.
