Introduction:

SV-820 non-contact speed meter for motor vehicles is an intelligent test instrument based on ARM's latest CORTEX core 32-bit single-chip microcomputer, with uCOS II real-time multi-tasking operating system for the power performance and safety performance of various automotive vehicles. Test of performance, etc. The SV-820 non-contact speed meter system uses 240*128 large-screen liquid crystal display, prompting Chinese characters, real-time display of multiple test data, curves, clear and intuitive. Test items are menu-driven and easy to use. Sensor coefficients and test parameters are automatically stored in the system, and power loss is not lost. Repeated input is not required. The machine design meets ergonomics and is easy to operate. It is an ideal teaching equipment for the auto manufacturing industry, automotive maintenance industry, automotive testing, scientific research departments, and agricultural machinery testing departments.
