Non-contact speed tester an overview of CTM-8A of non-contact speed tester, Zibo Micro-Electronics Co., Ltd. independently developed high-performance microprocessor as the core of the intelligent tester to test the vehicle dynamic performance, economy test performance, handling performance and the like. The system uses a liquid crystal display, character tips, real-time display multiple test data, curves, clear and intuitive. Test project using menu-driven operation, easy to use. Sensor coefficient and test parameters automatically stored, non-volatile, without re-entering. Ergonomic machine design, easy to control, is an ideal teaching instrument automobile manufacturing industry, the automotive repair industry, automotive testing, research departments and agricultural departments of the ideal testing equipment to detect and universities automotive area. System built 40 miniature printer, you can easily test results and test data, dynamic curve printed. And is equipped with a standard RS232 interface, test results can be sent to other computers, but also by the system control machine, complete the test project. Users to use the system or notebook computer can be easily performed a secondary analysis of the data processing or storage. (Data Format Appendix) system to provide a "comprehensive test" test program, the flexibility to set the start and end conditions of the test conditions, the freedom to complete the various test projects, flexible and efficient. ? Second, the main test items glide test: sliding velocity, sliding distance, sliding brake test of time: the average muzzle velocity deceleration braking, braking distance, braking time, maximum deceleration, the average deceleration, MFDD (fully developed? ) Speed ??Test:?? test distance, test time, average speed (minimum steady speed, the maximum stable speed) acceleration test: acceleration distance, acceleration time, speed and acceleration at the end of a shift start and end of the speed, distance, time integrated? test: two kinds of start condition, four kinds of end conditions, flexible portfolio into eight test methods, can complete a variety of road tests. Third, the technical performance of the system power consumption:? Less than 10W (static power 5W) built-in power:? DC9.6v external power supply:? DC12V standard 9-pin RS232 interface?. (3 feet signal output, 2 feet signal input, 5 feet signals). 9600 baud, 8 data bits, 1 stop bit and no parity. ? Dimensions: 220X 200 X 70 mm Weight:? 1 kg (including the built-in battery) Operating temperature:?? 0 ℃ ~ 40 ℃ Humidity: 30% to 80%
