Motor Circuit Analyzer

ALL-TEST Pro is pleased to introduce its new portable electric motor circuit analysis instrument, the ALL-TEST PRO® 5 (AT5). The AT5 performs a comprehensive assessment of a motor’s health for troubleshooting, predictive maintenance and quality control of in-service, stored and incoming motors. This hand-held, lightweight instrument performs de-energized static and dynamic testing to detect faults at their earliest stages – including deteriorated or contaminated insulation – and trends potential winding faults in AC and DC motors, transformers (distribution and transmission), generators, alternators and more. Intuitive on-screen, menu-driven prompts guide users through the testing process – no manual is needed and no training is required. A complete picture of the entire motor circuit is displayed within minutes, including resistance, inductance, impedance, capacitance, phase angle and more. This rapid evaluation of the stator, rotor, connections, contamination and ground faults enables the user to determine the motor’s viability on the spot. Good/Warning/Bad indicators and an included quick reference guide assist with more detailed assessments.

Tests can be performed directly at motor terminals or, in the case of hard-to-reach motors (such as those on overhead cranes or submersible pumps), from distances >1000 feet. The AT5’s internal memory can store up to 500 tests for immediate comparison to a previous test. Included software provides expert diagnostics, trending and a wide variety of printed or on-screen reports. Test results can be easily uploaded to a computer for storage and further analysis. Moreover, motor test routes can be created and downloaded to the instrument. The ALL-TEST PRO® 5 weighs 1.5 lbs. and comes standard with: 3 test leads with heavy duty Kelvin clips and push-pull connectors; one test lead with 4mm safety plug and MC dolphin clip; charging adapter; MCA BasicTM software; a rugged, hard-sided case with custom storage liner; and a user manual on CD. Optional accessories include smaller Kelvin clips, MCA PROTM software, a training demo motor and a soft carrying pouch.
