You can safely, easily, and quickly diagnose all kinds of motor failures and deterioration in just a few minutes!
【AT7PRO Main Features】 ■ The diagnostic results for each measurement item are displayed on the screen as OK, WARN, or BAD. ■ Diagnosis can be performed from the control panel without disassembling the motor. ■ Testing can be safely conducted at a low voltage of just AC10V, without damaging the motor. ■ Test data for over 650 motors can be stored in the diagnostic device itself. ■ By uploading the test data stored in the diagnostic device to dedicated PC software, data management and trend management for each motor become possible. 【Measurement Targets】 Induction motors (squirrel-cage, wound), synchronous, DC, transformers, generators 【Test Items】 ■ DC resistance ■ Loss factor (dielectric loss tangent) ■ Impedance ■ Inductance ■ Phase angle ■ Current frequency response ■ Insulation resistance ■ Rotor defects A budget version, 'ALL-TEST PRO7', is also available. * Testing for DC motors and transformers has been removed. On-site demonstrations are available; please feel free to contact us.
