Advantages of the ALL-TEST PRO 7™If you and your company are looking for superior handheld testing equipment, you’ve come to the right place. Our ALL-TEST PRO 7™ electric motor testing device can be used to detect motor abnormalities in machinery across every industry. This device features easy-to-use motor testing technology to detect motor abnormalities.

Our handheld motor testing devices outperform our competitors’ products in both quality and usability. While most similar products are able to detect only ground faults, the ALL-TEST PRO 7™ has the ability to detect motor failures before they occur and is a critical component of maintaining a facility’s productivity and overall ROI.

With the high-tech capabilities of the ALL-TEST PRO 7™, you and your technicians can easily detect even the most subtle imbalances in any motor. This function is incredibly important for the detection of stator coil. With this handheld product, you can easily gather a full picture of any given motor’s conditions right in one place — long before your motors fail as a result of preventable issues.

Uses for the ALL-TEST PRO 7™

You can use the ALL-TEST PRO 7™ to boost your motor testing methods. Test any motor’s resistance, stator, rotor, contamination and insulation stats all on one device and receive accurate diagnostics within as little as a few minutes.

With our ALL-TEST PRO 7™, you can use our patented Stator and Rotor Signatures™ to test the squirrel-cage rotor and stator with a single assessment. You can also diagnose common fault types using this product’s patented Test Value Static™ (TVS™), which provides a sum calculated from a 3-phase MCA static assessment.

This product tests every AC motor type. It evaluates the electrical health of synchronous, single-phase motors by assessing their stator wings, rotors, cables and other components.

Patented Dynamic Stator and Rotor Signatures™

Used to evaluate the condition of the stator and squirrel-cage rotor in a single test. Perfect for testing new and repaired motors prior to acceptance.

Patented Test Value Static™ (TVS™)

Test Value Static (TVS) 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.

ALL-TEST PRO 7™ Features

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

Boot loader function facilitates firmware updates at the customer’s site

Motor Circuit Analysis Software:

MCA™ Software

Deenergized Motor Circuit Analysis (MCA™) Software

MCA™ software enables you to manage your plant’s motors efficiently and easily. Track, trend and report on the condition of your plant’s motor assets in one software program. Share data to schedule maintenance and avoid downtime, unforeseen repair costs and improve worker safety. Trend assets and productivity and schedule maintenance based on facts and production schedules.

ALL-TEST Pro’s MCA Software enables analysis, quality control, troubleshooting and predictive maintenance for complete deenergized motor testing. The software compliments the AT7™, AT7™ PROFESSIONALAT34™ and AT5™ to create a complete analysis package for monitoring and maintaining electric motors and transformers.

Our MCA software’s intuitive analytics take the guesswork out of interpreting test results, including built-in diagnostic algorithms and trending as well as seven options for thorough, flexible report types.

MCA™ Software Features

Comprehensive Database

The core of the MCA so¬ftware is a database that collects and organizes the nameplate information and individual test results from all of your motors and transformers. A powerful, integrated search functionality enables access to data across all companies and locations by motor voltage, horsepower/kW, RPM, etc.

Evaluate New and Repaired Motors for Quality Control

Unlike other suppliers of motor testing equipment motor nameplate information is not required to evaluate the condition of the motor. Acceptance testing means YOU are in control of your motors program. The first test provides the baseline for future comparison.

*Requires MCA PRO Enterprise software only.

Motor Diagnostics for Troubleshooting

MCA™ Software applies proprietary algorithms and automatically diagnoses likely motor faults, taking the guesswork out of interpreting test data. The reporting feature displays a tabular and graphic view of the results which are easy to interpret and understand.

Motor Tending for Predictive Maintenance

All test data can be trend-graphed for condition monitoring. Condition based monitoring allows you to see deteriorating conditions that will need to be rectified in the near future. Planning for repairs and avoiding unscheduled downtime saves you money and time.

Scheduling and Review

  • Review motor assets to be tested by date.
  • Retest based on motor trend condition.
  • Or retest based on alarms.

You are even able to record additional test data for each motor such as infrared, vibration and other technologies you currently utilize to track assets.

Manage Assets by Location
Records can be grouped by buildings or process by manufacturing sites and also by customer name and location for service organizations. The user can quickly identify equipment marked Bad, Warning or Testing Past Due and the location of each asset.
