AUTOOL DM301 Auto Digital Multimeter Car Circuit Tester

The AUTOOL DM301 automotive digital multimeter is a handheld diagnostic multimeter that combines digital multimeter functions with a single-channel oscilloscope. It is designed for vehicle circuit testing, voltage, current, resistance, frequency, diode, ignition pulse signal, and basic waveform observation in automotive maintenance. DM301 is shipped without batteries. Confirm the battery type before use, and do not charge dry batteries through the device. DM301 is the compact choice for core multimeter and oscilloscope work. DM303 is the higher-function model for users who need more automotive-specific diagnostic modes and more test lead options. DM301 combines a clear display, portable toolbox, oscilloscope function, auto range measurement, multilingual interface, SD card software upgrading, and 3-year warranty support. DM301 covers common automotive electrical measurements and waveform checks, making it useful for circuit diagnosis, sensor signal observation, and ignition pulse signal testing. DM301 is suitable for common vehicle circuit diagnostic scenarios where voltage, current, resistance, frequency, diode, ignition signal, and waveform observations are needed.
