Getting quick, accurate results on your motors’ performance has never been easier!

This top-selling product provides an array of advantages you won’t be able to find anywhere else. The ALL-TEST PRO 7™ PROFESSIONAL motor testing equipment features our patented Dynamic Stator and Rotor Signatures™ for AC induction squirrel-cage rotor motors rated less than 1000V, which enable technicians to instantly assess a motor’s squirrel-cage rotor and stator. It also features our patented Test Value Static™ (TVS™), which is employed as a reference value to test for faults in a motor or incoming power leads.


Uses for the ALL-TEST PRO 7™ PROFESSIONAL Testing Equipment

The ALL-TEST PRO 7™ PROFESSIONAL can be used to perform a variety of tests that evaluate AC induction motors, generators, rotors, DC motors and much more. For a complete list of the ALL-TEST PRO 7™ PROFESSIONAL’s test capabilities, see the product information below.

The ALL-TEST PRO 7™ PROFESSIONAL can be used for virtually any type of motor. No matter your industry, this advanced testing device will help you increase productivity by preventing machine failures, which cause companies to lose hours upon hours of valuable production time and thousands of dollars in lost work.

Patented Dynamic Stator and Rotor Signatures™

Evaluate the condition of the stator and squirrel-cage rotor in a single test. This instrument is perfect for testing new and repaired motors prior to acceptance.

Patented Test Value Static™ (TVS™)

Test Value Static™ is a sum calculated from the 3-phase MCA static test and is used as a reference value for the motor. Common types of faults in the rotor and stator windings will change TVS.
Obtain Return On Investment

Finding just one fault using the AT7™ PROFESSIONAL can save your organization countless hours of downtime and provide thousands of dollars in savings. Maximize your investment by:

  • Testing newly installed motors to ensure proper installation and prevent startup failure.
  • Testing motor spares to ensure they are in good condition and ready for service.
  • Troubleshooting motors that have quit running by testing from the MCC or directly at the motor.
  • Implementing it into a PdM testing program to detect developing faults before they cause catastrophic motor system failures. Finding a motor fault before it breaks can save you countless hours of downtime and can provide thousands of dollars in savings.

Test all types of electrical motors (any voltage) including AC (induction and synchronous) and DC (series, shunt, and compound), as well as transformers, generators, traction motors, machine tool servo, single-phase motors and other coil-based devices.
The electrical health of all motor components is evaluated, including, but not limited to:

  • Induction windings
  • Rotor
  • DC field windings and armature
  • Field and rotor coils in synchronous motors
  • Primary and secondary windings in transformers
  • All associated connections and cables

  • On-screen step-by-step testing instructions
  • Tests take less than 3 minutes
  • Tests can be performed from over 1000′ away
  • Detects faults at the earliest stages before motor failure
  • A timing tone that supports proper rotation speed during deenergized dynamic test
  • Route based testing and trending
  • Boot loader function facilitates firmware updates at the customer’s site

Discontinued — the ALL-TEST PRO 5™
