I. Main features of the micro-motor detector： 
This test machine is one model of a highly reliable micro-motor detector (DC micro-motor comprehensive detector, micro-motor comprehensive tester, micro-motor tester); reliable online detection technology for micro-motors has always been a challenge in the industry; this product adopts an industrial-grade digital signal processor (DSP) to sample the motor waveform signals and use a special digital filtering algorithm to analyze the waveforms. It can reliably and accurately analyze the motor's rotational speed data in complex waveforms that cannot be triggered stably by digital oscilloscopes. Its accuracy, stability, reliability, detection speed, and adaptability are at the leading level among similar products. National testing departments and many micro-motor factories have adopted our company's products. 
II. Application Scope of Micro-Motor Detector：
It is suitable for quality inspection of various specifications and models of DC motors, including: various three- and multi-phase DC motors used in products such as mobile phones, toys, audio equipment, automobiles, power tools, hair dryers, etc. It can accurately detect various hollow cup motors and carbon brush DC motors that are difficult to measure precisely, and can measure various performance parameters of the motors. It is a production line quality inspection tool for motor factories and complete machine factories. 
III. Main parameters of the micro-motor detector： 
1. Multi-functional, adaptable: All kinds of specifications and models of DC motors can be detected. They can all automatically adapt. The usage is equally simple, clear and efficient! 
2. Five-digit accuracy for rotational speed, high degree of precision, convenient reading, error less than 1%, current error less than 1%, voltage relative error less than 1%, error less than 0.02V. 
3. The rotational speed can be measured within less than 0.5 seconds. 
4. Overall machine dimensions: 34.3cm (width) * 13.3cm (height) * 30cm (length) 
5. Wide speed range: 500 - 99,999 RPM; 
6. Power supply capacity: 300W 
7. Wide current range: 0 - 4000 mA 
8. Overall machine weight: Approximately 7.5 kilograms; 
9. Wide voltage range: 0 - 30V (and can be customized to 40V, 55V, or for high-voltage requirements, additional purchase is required) 
10. Full digital setting: The setting is convenient and ensures that (the voltage can be set either in full digital mode or by a precise knob, among the two available setting options); 
11. Multi-functional: It can measure parameters such as rotational speed, current, and insulation resistance (Model C can perform forward and reverse automatic detection, and customized functions are also available); 
12. High reliability: Equipped with overload protection, using high-reliability industrial-grade components and undergoing strict product testing. 
IV. Operating Procedures for Micro-Motor Detector：
1. Acceleration mode: You can choose between "Acceleration Detection Mode" and "Regular Detection Mode". When in "Acceleration Detection Mode", it can meet the requirements for efficient detection. 
2. Alarm notification method: You can choose "Beep when the speed exceeds the upper or lower limit" (i.e., a beep sounds when the speed is incorrect) and "Beep when the speed is within the upper and lower limits" (i.e., a beep sounds when the speed is correct). 
3. Disable alarm notification sound: You can choose the "Allow buzzer to sound" option, which is the default setting at factory; or the "Do not allow buzzer to sound" option (i.e., turn off the alarm sound). 
4. Real-time data retention function: It enables the locking and retention of the actual measured rotational speed and current values, facilitating data recording by the quality inspection department and the engineering department. 
5. Leakage test: The insulation test voltage is divided into three levels: 100V, 200V, and 300V. The insulation resistance is also divided into three levels: 1M, 5M, and 10M. 
V. Precautions for the Micro-Motor Detector： 
1.Before conducting the test, please make sure that the power supply is properly plugged in or connected.
2. Before conducting the test, make sure that the product is properly installed and fixed.
3. The mechanical transmission parts must be maintained regularly.
4. After the test is completed, it is necessary to ensure that the power supply has been turned off.
5. It is strictly prohibited to use auxiliary corrosive liquids to clean the machine. Instead, rust preventive oil must be used.
6. This testing machine must be operated by a designated person. During the testing process, it is strictly prohibited to strike the machine or have anyone stand near it.
7. The machinery must be grounded.
