Product Information

AT7™

The ALL-TEST PRO 7™ (AT7™) is a fast, accurate, and fully portable motor testing instrument that brings the power of deenergized Motor Circuit Analysis™ (MCA) to any facility or field environment. Unlike traditional testers that only detect ground faults, the AT7™ identifies issues in insulation, stators, rotors, contamination, and connections—before they escalate to costly motor failure.

Designed for speed and simplicity, the AT7™ delivers full diagnostic results in less than 3 minutes and can be used from more than 1,000 feet away from the motor, making it ideal for hard-to-access systems or safety-sensitive environments. Built-in on-screen prompts guide technicians through each step of the test, ensuring accuracy and repeatability.

With features like a timing tone for deenergized dynamic tests and the ability to perform customer-side firmware updates via its bootloader function, the AT7™ empowers maintenance teams to stay ahead of failures, extend motor life, and maximize ROI.

This compact tool is widely used across industries, from manufacturing to utilities, and is trusted for predictive maintenance, quality control, and motor commissioning.

Rapid Motor Diagnostics—Anytime, Anywhere

The AT7™ delivers full motor diagnostics in under three minutes and can perform tests from over 1,000 feet away. It enables fast evaluations without removing the motor or applying power.

Early Fault Detection That Goes Beyond Ground Faults

Unlike conventional testers, the AT7™ detects winding faults, insulation issues, and rotor or stator imbalances—long before they become failures. It's an essential tool for predictive maintenance.

User-Friendly Interface and Step-by-Step Guidance

Built-in prompts walk users through each test step, while a timing tone ensures correct motor shaft speed during dynamic MCA testing. The interface is intuitive for both new and experienced users.

Designed for Flexibility and Long-Term Value

From its bootloader firmware updates to rugged handheld design, the AT7™ adapts easily to facility and field needs. It supports AC and DC motors in all sectors and helps safeguard critical operations with ease.
