Vehicle diagnostic multimeter, Autool DM303

Vehicle diagnostic multimeter, Autool DM303

Vehicle diagnostic multimeter is a new handheld diagnostic oscillometric multimeter that integrates a digital oscilloscope, digital multimeter, vehicle electrical circuit check function. It is designed using digital scanning and control technologies.

Features:

• 2.8" color screen: screen brightness can be adjusted, it displays parameters and data, easy to read and clear. Therefore, you will be able to work in various working environments without difficulty.
• Plastic device case: The main device and its accessories are stored safely and securely in their dedicated case, which protects them from external factors. It is shock and drop resistant. Also, the suitcase will provide convenience when carrying the device to different places.
• Oscilloscope function: the width of the measured waves reaches 500 kHz. Using a variable scan rate, you will be able to measure a slowly changing signal, monitor the technical condition of vehicles, measure and monitor the values of various signals generated in them. The device will also be able to easily read engine drive signals, engine power voltage in electric vehicles, ignition signals, camshaft signals, crankshaft signals, ABS sensor signals, oxygen sensor signals, etc.
• Auto Range and True RMS: Simply select the desired mode and plug in the wires. The multimeter will automatically select the appropriate measurement depending on what it detects. Using true RMS, the DM303 portable multimeter provides clear and accurate readings, always when and where you need them.
• Wire Functions: The device is equipped with 8 wire lines for different functions. One line is for multi-function measurement, battery terminal line, ignition pulse signal measurement line, multimeter line, etc. The multi-function test line is used for battery voltage, fuel injector and relay testing, K-line, CAN signals, car ECU and other various car parts testing.
• Multi-language management arts: support 12 languages, English, French, Portuguese, Polish, Spanish, Japanese, Russian, Italian, German, etc.
• Long warranty period

Functions:

• Multimeter: Detects 1000 V DC and 700 V AC voltage, measures 200 mA DC and AC current, and can measure resistance and diode conductance
• Oscilloscope: A hand-held oscilloscope is capable of measuring 500 kHz waves. By pressing one button, the value of the measured waveform is automatically displayed
• Ignition diagnostics: select the type of internal combustion engine, ignition system and calculate the rotational speeds of different engines, cylinders.
• Instructions for wire values
• 1 Hz ~ 1 MHz signal frequencies: To perform this measurement, the device must be connected to a potential signal source with a voltage greater than 1 V.
• Starting test: during this test, the minimum voltage of the battery is determined, it should be higher than 9.6 V in normal condition. And if the measured voltage is lower than 9.6 V, then the battery is dead.
• Nozzle testing: Ability to perform nozzle check, also can measure real-time nozzle signal. It can test electromagnetic injectors, including GDI injectors, but does not have the ability to support 120V injectors.
• Analog signal testing: The multimeter can simulate common 5V square wave and 5Vpp sine wave signal output, and can be connected to a battery pack to generate 12V square wave signals through a multi-function detection cable.
• True RMS measurement: Automatically adjust True Root Mean Square (TRMS) parameters for greater accuracy. The TRUE-RMS multimeter is ideal for a variety of electrical and electronic testing.
• Auto range function: automatically displays measured data, which significantly saves time compared to manual selection of measurement parameters.

Technical parameters:

• Measured voltage range: 0 - 1000 V / DC | 0 - 700 V / AC
• Range of measured electric current: 0 – 20 A; 0-200mA
