CTM-2008F series motor vehicle comprehensive tester

Series motor vehicle comprehensive tester 1. Overview
The series motor vehicle comprehensive tester (car tractor comprehensive tester) is independently developed by Zibo Chuangyu Electronics Co., Ltd. with R high-performance 3-bit single-chip microcomputer as the core Intelligent testing instruments are used to test vehicle power performance, economic performance, handling performance, and tractor traction performance. The system uses a large-screen LCD display with Chinese character prompts to display multiple test data and curves in real time, which is clear and intuitive. The test items adopt menu-based operation, which is simple and easy to use. Sensor coefficients and test parameters are automatically stored by the system and will not be lost after power failure, and there is no need to re-enter. The whole machine design conforms to ergonomics and is easy to control. It is an ideal testing equipment for the automobile manufacturing industry, automobile maintenance industry, automobile testing, scientific research department and agricultural machinery testing department, and an ideal teaching instrument for automobiles in colleges and universities.
The system has a built-in micro printer, which can easily print out test results, test data, dynamic curves, etc. It is also equipped with a standard R3 interface, which can send test results to other computers or be controlled by the system computer to complete the entire test project. Users can easily perform secondary analysis, processing or storage of the data using a system computer or laptop. (See the appendix for data format details)
This machine provides a level self-check signal of . (corresponding to a vehicle speed of .km/h), which facilitates calibration and maintenance of the instrument.
This system can be equipped with two fuel consumption sensors, and can easily and accurately test the actual fuel consumption of vehicles with large oil returns.
