This device is used to record necessary integrated information for testing vehicles, including driving parameters, the movement times of inner equipment or components, the function parameters of engine and sensors. It can record the speed, running speed of the engine, timing, driving distance, driving time, shift position, problem code and time, and stop times. According with the need of clients, it can be added other functions, such as recording the driving parameters engine and sensors, and other running times of some equipments and parts, such as cooling liquid temperature, suction pressure, SA spark advance storage battery pressure, entering gas temperature, oxygen sensor voltage and throttle open. The other 8 parameters that can be displayed are braking times, air conditioner switch times and fan switch times. Via twice data process software, the above recording curve and data can be showed. The previous record for a period even can be counted and handled by statistics software, including overall driving distance, overall driving time and driving mileage of different shifts. producing area:China payment:T/T in advance, L/C supplying capacity:1,000pcs/day
