Description
The Autel MaxiEV ITS100 EV Insulation Resistance Tester is a professional diagnostic tool designed for high‑voltage systems in electric and hybrid vehicles. It evaluates the insulation resistance of high‑voltage cables, connectors, battery packs, and other electrical components by applying selectable DC test voltages (50 V, 100 V, 250 V, 500 V, or 1000 V) and measuring the resulting current flow. This helps identify issues such as insulation damage, deterioration, or contamination before they lead to safety hazards or system failures.
Equipped with multiple measurement modes — including relative comparison, timely tracking, and continuity tests — the ITS100 delivers visualized data that technicians can interpret easily for informed decision‑making during maintenance procedures.
Its built‑in functions also allow automatic power‑off to conserve battery life and capacitor discharge to clear residual voltages before testing. The unit complies with international safety standards (IEC/EN 61010‑1 1000 V CAT III and 600 V CAT IV), making it suitable for use in workshop environments where high‑voltage safety and accuracy are essential.
Common applications include pre‑service insulation checks, fault diagnosis in high‑voltage electrical systems, and safety verification on EVs and hybrid vehicles, helping technicians ensure reliable and safe operation of electric drivetrain components.
