SG-630 portable braking performance tester

SG-630 portable braking performance tester (upgrade version) Introduction I. Overview SG-630 portable braking performance tester, Zibo SEG Electronics Co., Ltd. is the latest self-developed with ARM CORTEX-M3 microcontroller core 32 core handheld intelligent devices, with uCOS II real-time multitasking operating system, an integrated sensor chip to complete a variety of high-speed acquisition parameters during testing, processing, to test the car's braking safety performance. This instrument is mandatory according to the latest national standard GB7258-2012 "safe operation of motor vehicles technical conditions" Road Test braking performance test requirements developed for motor vehicle braking performance testing and accident investigation. The instrument uses 192 * 64 large LCD display, Chinese prompt, clear and intuitive. Test items using menu-driven operation, easy to use. Test data and test curve can be synchronous memory (can store a total of 300 groups of test data), test data for later viewing, analysis and printing. The automotive manufacturing industry, automotive repair industry and automotive testing, scientific research departments ideal test equipment. The machine is portable, compact, equipped with powerful magnets on the external sensor, easy to install, but also for testing on small space vehicles. The instrument can enter an eight-digit number plates and the word province, and enter the "police", "school", "hanging" and other characters. System is equipped with a standard RS232 interface, it can be connected with an external micro-printer, print test data and curves. Test results can also be sent to other devices or computers, flexible constitution online test system. System built-in USB interface. Testing of the system with Windows software, you can test data transmission curve to notebook computers, to achieve mass storage, printing and other functions test data. The system can also optional Bluetooth wireless transmission module, wireless transmission of test data, test curve. ?
