Outline

This series instrument, is take INTEL Corporation MCS-96 series high performance 16 monolithic microcomputers as the core intellectualization measuring instrument, with by tests the automobile dynamic quality, the economical performance, the handling quality, as well as tractor tractive quality test. The system uses the 240*128 large screen liquid crystal display, the Chinese character prompt, the real time display test data, the curve, clear are direct-viewing. The test project uses the vegetable unitary operation, simple is easy to use. The sensor coefficient as well as the test parameter system automatic memory, falls the electricity not to lose, does not need to duplicate inputs. Is the automobile manufacture profession, the automobile service profession as well as the automobile examination, the scientific research department ideal check-out facility.

In the system sets at 40 rows miniature printers, but conveniently tests the result as well as the test data dynamic curve prints. This machine may to test the result automatically to carry on the memory, each test project altogether may save 10 time (tows experiment is 30), after shutdown, the data won't lose. And has the standard RS232 connection, may test the result to transmit, the user either the notebook computer may conveniently carry on two times of analyses processing or the memory using the system machine to this data.

This system may match meets two groups oil consumption sensors, to returns to the oil mass big vehicles to be able to be convenient, accurately to test its actual oil consumption.

CTM2002A does not have the force of traction project test, does not have corresponding pulls presses the sensor and the rotation sensor; CTM2002B has the force of traction project test.

Main test projects
»Taxiing test: Slides the initial speed, the skidding distance, the taxiing time
»Brake test: Applies the brake the initial speed, the stopping distance, the stop time, reduces the speed, the average most greatly reduces (average which the speed, MFDD fully sends out to reduce speed)
»Vehicle speed experiment: Experimental distance, experimental time, average vehicle speed (lowest stable vehicle speed, maximum stable vehicle speed)
»Acceleration test: The acceleration distance, the rise time, the acceleration end speed as well as shift gears to start and to finish the time speed, the distance, the time
»Constant speed oil consumption: Experimental distance, experimental time, average velocity, constant speed oil consumption (hundred kilometers oil consumptions), hour oil consumption
»Acceleration oil consumption: Acceleration end speed, experimental distance, experimental time, average velocity, acceleration oil consumption, hour oil consumption
»Operating mode oil consumption: Experimental distance, experimental time, average velocity, hundred kilometers oil consumptions hours oil consumption
»Tows the experiment: Experimental distance, experimental time, average velocity, force of traction, pulling power, rotation, slipping rate, hour oil consumption, ratio oil consumption

Technical performance target

Matters needing attention
»this instrument is the precision instrument, please note the handle with care in the use process, and avoids fiercely vibrating.
»in the use process, should avoid the glare long time illumination liquid crystal screen, in order to avoid liquid crystal screen aging.
»when meets inserts the sensor, should be careful carefully, in order to avoid meets wrong burns out the instrument and the sensor. The electro-optical sensor is the precious sensor, asks the user to pay attention specially.
»after turns on the power switch, if the power light is not bright, the screen does not have any demonstration, please inspect the fuse is whether complete. When necessity please replace the same specification the fuse (2A).
»when the power light extinguishes, namely the expression interior battery owes the electricity, needs to charge. Please use the special-purpose battery charger which the instrument provides to carry on the charge operation, usual 10 hours then.
»the instrument provides internal battery, only is the short time experiment or the demonstration using of, like enters president the time experiment, should use the external power supply.
»in test process, when the pressed key does not have the response, the screen demonstration no change, please press "the replacement" the key, makes the instrument reto start. Or the shutting down power switch, after crosses a while, again returns on the power switch to carry on the test.
