Features

• 2.8-inch Color Display: Adjustable screen operation with clear and intuitive data, suitable for various work environments.
• Plastic Toolbox: Effectively organizes the main unit and accessories for easy portability, with a drop-resistant and impact-resistant design to protect the instrument.
• Oscilloscope Functionality: 500kHz waveform testing bandwidth with variable sampling frequency to measure slow-changing signals. Suitable for automotive repairs, it can observe various signals in automotive circuits, including motor drive signals in electric vehicles, power supply voltage of motors, ignition signals in gasoline engines, camshaft signals, and crankshaft signals.
• Automatic Ranging and True RMS: Simply select the mode and connect the leads. The multimeter will automatically select the appropriate measurement value based on what is detected. With True RMS, the DM303 portable multimeter provides clear and accurate readings anytime, anywhere.
• Wiring Functionality: Equipped with 8 leads for various functions, including multifunctional testing leads, battery clip leads, ignition pulse signal test leads, automotive circuit test leads, jumper wires, and multimeter probes. The multifunctional testing leads can check battery voltage, fuel injectors, relays, K-line and CAN bus signals, automotive ECUs, and other components.
• Multilingual Support: Supports 12 languages: English, French, Portuguese, Polish, Spanish, Japanese, Russian, Italian, German, Dutch, Korean, and Chinese.

Application Scenarios

• Suitable for various automotive repair scenarios, including automotive circuit communication checks, ignition signal diagnostics, and injector testing.

Highlights & Innovations

• Multimeter Testing: Detects up to 1000V DC and AC voltage, measures up to 200mA DC and AC, and tests resistance and diodes.
• Oscilloscope Function: Portable oscilloscope with a 500kHz bandwidth. One-button automatic waveform display.
• Ignition Diagnostics: Select engine cylinder type and ignition to calculate the RPM of different engine cylinders.
• Electrical Measurement Instructions:
  • 1Hz~1MHz Signal Frequency: Requires connection to a voltage signal source greater than 1V for measurement.
  • Start Test: If the battery’s minimum voltage is above 9.6V, the vehicle start test indicates normal operation. If the voltage drops below 9.6V, it may indicate battery aging.
  • Injector Testing: The multimeter can drive the injector for testing, as well as detect real-time injector signals. It can test electromagnetic injectors, including GDI injectors, but does not support 120V injectors.
  • Analog Signal Testing: The multimeter can simulate a 5V square wave and a 5Vpp sine wave signal, and can also produce a 12V square wave signal using multifunctional testing leads connected to a battery.
  • True RMS Multimeter: Automatic ranging True RMS technology enhances accuracy. The True RMS multimeter is ideal for various electrical and electronic testing applications.
  • Automatic Ranging Feature: Automatically displays measurement data, eliminating the cumbersome process of manually selecting the measurement range.
