INTRODUCTION
Congratulations on your purchase of the new patented ALL-TEST PRO 7™ PROFESSIONAL (AT7P)
or ALL-TEST PRO 7™ (AT7™) Motor Circuit Analysis
TM
(MCA
TM
) instrument from ALL-TEST Pro,
LLC (ATP).
The AT7 series offers a complete motor testing system solution for stand-alone
troubleshooting/fault localization, quality control of stored or incoming new/repaired motors,
as well as data collection and trending for early fault detection when combined with the
comprehensive MCA Basic™, MCA PRO™, or MCA PRO™ Enterprise computer software.
The AT7 series performs MCA through a series of low voltage tests to identify faults inside an
electric motor. It detects winding contamination, stator faults such as turn-to-turn and coil-to-
coil shorts, open connections, ground faults, and broken/fractured rotor bars. Experience has
proven that the ALL-TEST PRO® series of MCA instruments are the most powerful and easiest to
use diagnostic tools available for deenergized testing of motors in today’s industry.
The AT7 series is designed to be used as a stand-alone unit in the field or workshop with or
without the software. MCA Basic and MCA PRO software provides for further analysis, reporting,
trending and database management. MCA Basic comes standard with the AT7 and is used for
single and three phase AC motor analysis, trending, and reporting. MCA PRO comes standard
with AT7P which includes DC motor and transformer analysis, plus unique rotor grading method
along with route-based testing.
The AT7 series has a built-in real time clock and large memory for storage of test and reference
data. The instruments are built to exacting standards and rugged to handle the daily use in
tough industrial environments. The rechargeable Lithium batteries support eight hours or more
testing and data collection*.
* Assumes most testing is phase to phase. Performing insulation to ground testing in applications where
there are long cables running will increase the drain on the battery. Therefore, user may not get 8 hours of
use between battery charges.
