Launch EM101N EV Oscilloscope & Multimeter

Description

The Launch EM101N EV Oscilloscope & Multimeter is a combined diagnostic instrument that integrates both a dual-channel oscilloscope and a multimeter into a single portable unit built for electric vehicle (EV) electrical system diagnostics. This tool enables technicians to precisely measure and visualize electrical signals such as voltage, current, resistance, and waveform patterns — essential for troubleshooting complex circuits in high-voltage EV battery systems and power electronics.

Unlike standalone multimeters, the EM101N provides oscilloscope capabilities that allow real-time waveform analysis, making it easier to detect abnormal fluctuations and irregularities that can indicate deeper system faults. The unit includes a user-friendly diagnostic app with multiple display modes, supports both wireless and wired connection with compatible X-431 diagnostic tools (e.g., PAD V, PAD VII, EURO TAB III), and lets users save and revisit waveform data locally for more thorough analysis.

The EM101N features rugged construction with anti-fall rubber protection, a 3,100 mAh rechargeable battery for portable use, and a complete set of accessories — including test probes, BNC leads, alligator clips, and multimeter test pens — to support versatile testing workflows across EV and high-voltage applications.
