DM303 is a new car diagnostic multimeter launched by AUTOOL It was specially developed for the field of vehicle maintenance. It is a multifunctional instrument that can measure and monitor vehicle circuit systems. It not only has the functions of a multimeter and an oscilloscope, but also supports vehicle circuit detection, ignition pulse signal detection, relay testing, fuel injector detection, and reading K-line and CAN bus data of the vehicle OBD system . The device can be used for various types of vehicles such as trucks, cars, buses, electric vehicles, etc. Maintenance master. Characteristics: ① Multimeter function It can measure DC, DC Voltage, AC Current, AC Voltage, Resistance, Diode Forward Voltage, On-Off, Frequency, etc. with high measurement accuracy. ②Oscilloscope function The oscilloscope mode is a complete intelligent measurement system, including signal input, data acquisition, data processing and automatic search. The waveform test bandwidth is 500 kHz. It uses a variable sample rate and can measure slowly changing amounts of signals. It is suitable for measuring and observing various amounts of signals in vehicle circuits during vehicle maintenance, including engine drive signals and engine power voltages in new vehicles, ignition pulse signals, camshaft signals, crankshaft signals, wheel speed sensor signals, oxygen sensor signals, etc. of motor vehicle engines. ③ vehicle circuit system detection It can detect the car's low voltage circuit, indicate high voltage or line leakage, and output the power supply voltage to test the parts on the car or the voltage to operate the parts on the car, such as: B. lights to reduce. It can also measure the battery voltage when the engine is started and determine whether the vehicle starting system and battery are in good condition. ④ Analog signal output Analog signal output can be used for vehicle ECU detection, square and sine wave analog output, analog fuel injection signal for driving fuel injector, and data signal line K-Line and CAN bus signal detection in vehicle. ⑤ Portable tool box included The main unit and accessories can be easily stored, which is convenient to carry, and the case is shockproof and impact-resistant, effectively protecting the equipment. ⑥ 2.8 inch color display The screen brightness can be adjusted for use in dark environments. Users can complete the operation using the buttons on the operation panel. for different working environments. ⑦ Unique appearance design Back Stand: Can be stably placed on the workbench when used for examination, which is convenient for operation. It can also be folded to save space when not in use. Illumination Lamp: Can be used in the dark environment, which is convenient for technicians in maintenance. Test line socket: The test line can be plugged in and fixed smoothly, and there is an identification information design on the socket. ⑧ Three-year warranty, lifetime maintenance For damage caused by non-human factors, AUTOOL Occasional Technology promises to replace the parts for free within 3 years.
