AUTOOL DM303 Digital Diagnostic Tester Oscilloscope Multimeter 12 Test Functions

About this deal

The AUTOOL DM303 is a handheld automotive diagnostic tool that integrates a digital oscilloscope, digital multimeter, and car circuit and signal inspection into a single device. As well as supporting ignition pulse signal detection, relay testing, and injector diagnostics, it reads K-line and CAN-bus data from a vehicle's OBD system, making it applicable to cars, trucks, buses, and electric vehicles. The multimeter side measures AC/DC voltage, resistance, continuity, AC/DC current, capacitance, frequency, diodes, duty cycle, and ignition signals. The built-in oscilloscope offers a waveform test bandwidth of 500 kHz and can observe signals such as motor drive signals, ignition signals, camshaft and crankshaft signals, wheel speed sensor signals, and oxygen sensor signals. Auto-range means you simply select the mode and connect the leads, with True RMS ensuring accurate readings. A 2.8-inch colour screen with a resolution of 320x240 displays results clearly.
