AUTOOL DM303 Auto Diagnostic Digital Multimeter Oscilloscope Ammeter Analog Signal Test Ohmmeter Car Circuit Tester with K/CAN

AUTOOL DM303 Auto Diagnostic Digital Multimeter Oscilloscope Ammeter Analog Signal Test Ohmmeter Car Circuit Tester with K/CAN

Take the guesswork out of automotive electrical diagnosis.

The AUTOOL DM303 Automotive Diagnostic Multimeter is the advanced version of AUTOOL's automotive multimeter platform, combining 13 testing functions with oscilloscope, component-drive and vehicle communication-line testing. It is suited to technicians who need to move beyond basic voltage and resistance checks into signal, injector, relay and CAN/K-LIN diagnosis.

Why This Tool Is Useful
