CTM-2004F Vehicle Tester Introduction I. Overview CTM-2004F Series Vehicle Tester (automobile and tractor Tester) is a high-performance microprocessor core road Zibo Micro-Electronics Co., Ltd. independently developed test instrumentation for testing vehicle power performance, economic performance, handling performance and tractor 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 can be automatically stored, non-volatile, without having to re-enter; the machine is designed to meet ergonomics, ease of handling, the instrument is ideal for teaching equipment vehicle manufacturers, vehicle inspection, vehicle maintenance, research departments, road transport sector and agricultural safety supervision departments of the ideal testing equipment and automotive aspects of universities. System built-in mini-printer, you can easily test results and test data, print out the dynamic curves; the use of computer users to easily perform a secondary analysis of the data processing or storage (data format see Appendix). The system can be connected with two fuel sensors on the back of oil can easily be larger vehicles accurately test the actual fuel consumption. (Standard configuration: a fuel sensor.) The instrument complies with GB7258 "the safe operation of motor vehicles technical conditions" requirements. ? 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, fuel consumption? Test:? hundred kilometers: the distance test, test time, average speed, 100 km fuel consumption, fuel consumption hours constant fuel consumption:? distance test, test time, average speed, fuel consumption constant (100km ? amount), hour fuel consumption accelerated consumption: Accelerated end speed, distance test, test time, average speed, fuel consumption acceleration, fuel consumption six hours working condition fuel consumption:? test distance, test time, average speed, one hundred kilometers ? h fuel consumption fuel consumption traction test: test distance, test time, average speed, traction, traction power, rpm, slip rate, hourly fuel consumption, fuel consumption than three technical performance indicators system power consumption:? less than ? 10W (static power 5W) built-in power: DC9.6v (1.2v 4AH NiCd 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 and no parity. ? Dimensions: 370 X 260 X 90 mm Weight:?? 4.5 kg (including the built-in battery) Operating temperature: -10 ℃ ~ 40 ℃ Humidity: 30% -80%
