WYH-1A microcomputer fuel consumption tester

-Type microcomputer fuel consumption tester 1. Overview
-Type microcomputer fuel consumption tester is an intelligent testing instrument independently developed by Zibo Chuangyu Electronics Co., Ltd. with the company's series of high-performance single-chip microcomputers as the core. To test the economic performance of the car, both bench testing and road testing can be performed. The system uses a large-screen LCD display with Chinese character prompts to display test data 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 other parameters are not lost when power is turned off, and there is no need to re-enter them. It is an ideal testing equipment for the automobile manufacturing industry, automobile maintenance industry, automobile testing and scientific research departments.
The system has a built-in micro printer that can easily print out test results. It is also equipped with a standard R3 interface, which can send test results or be controlled by other host computers to flexibly form an online test system.
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.
