Product Information

AT34 EV™

The ALL-TEST PRO 34 EV™ (AT34 EV™) is the first and only handheld motor diagnostic instrument specifically designed to test permanent magnet motors and generators used in electric and hybrid vehicles. Combining MCA static and dynamic test modes, the AT34 EV™ delivers comprehensive insight into the electrical and mechanical health of EV/HEV propulsion systems—without disassembly or high-voltage energization.

Technicians can complete a full motor evaluation in under three minutes using the AT34 EV™. The static test captures resistance, inductance, impedance, capacitance, and phase angle, while the dynamic test evaluates rotor, stator, contamination, and resistance—all from a lightweight, intuitive device.

Unlike other tools limited to post-failure diagnostics, the AT34 EV™ excels in preventative maintenance. It enables automotive and fleet professionals to detect early-stage issues—such as rotor degradation or winding imbalance—before they evolve into major repairs or roadside failures.

Built for both shop floors and mobile testing, this durable, CE-compliant instrument helps eliminate unnecessary downtime, extend motor lifespan, and improve service team efficiency.

Designed for EV and Hybrid Motor Diagnostics

The AT34 EV™ is the only MCA tool engineered specifically for permanent magnet motors and generators found in electric and hybrid vehicles. It gives EV maintenance teams unmatched confidence when assessing motor systems.

Two Testing Modes, One Easy Interface

Static testing measures inductance, impedance, resistance, and phase, while dynamic testing evaluates rotor and stator health. Step-by-step instructions on the device guide users through every test sequence.

Portable and Non-Invasive Testing

Test motors directly in the vehicle—no disassembly or high-voltage conditions required. The AT34 EV™ delivers accurate insights from a safe distance in the shop or field.

Prevent Problems Before They Fail

By detecting faults in stators, rotors, and cable connections early, the AT34 EV™ helps reduce costly motor failures and downtime. It’s an essential tool for EV service, quality assurance, and fleet diagnostics.
