The fifth round instrument - contact five meter

CTM-2002A / B five meter I. Overview CTM-2002A / B five instrument is Zibo Micro-Electronics Co., Ltd. self-developed high-performance microprocessor core road test instrumentation for the test vehicle dynamic performance, testing economic performance, handling performance; the system uses a liquid crystal display, a number of real-time display of test data, curves, clear and intuitive; test project using the menu-driven operation, easy to use; sensor coefficient, test parameters automatically stored, power-down is not lost; ergonomic machine design, easy to control, the instrument is in automobile manufacturing, automobile comprehensive performance testing, agricultural machinery manufacturing, research departments, road transport sector as well as the ideal testing equipment agricultural safety supervision departments and universities of automotive ideal teaching equipment. System built-in mini printer, you can easily test results and test data, dynamic curve print out; users to use a computer to easily secondary analysis of the data processing or storage (data format see Appendix). ? Second, the main test items taxi tests: sliding velocity, sliding distance, sliding time brake test: average deceleration brake initial velocity, braking distance, braking time maximum deceleration, the average deceleration, MFDD (fully developed? ) Speed ??Test:?? test distance, test time, average speed (minimum stable speed, the maximum stable speed) acceleration test: acceleration distance, acceleration time, velocity and acceleration at the end of the shift start and end of speed, distance, time, three, Technical performance indicators system power consumption:? less than 10W (static power 5W) built-in power:? DC9.6v (1.2v 4AH NiCd battery 8) External power:?? 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, no parity. ?
