The handheld ALL-TEST IV PRO™ (ATIV™) is an excellent analytical instrument for detecting and trending potential winding faults in AC and DC motors, transformers (distribution and transmission), generators, alternators, and other devices with windings. The ATIV™ is also used for de-energized rotor testing for issues such as eccentricity, broken/fractured rotor bars, and casting voids.
The ATIV™ makes the following 5 measurements plus an insulation to ground test:
Resistance (R), phase angle (Fi), current/frequency response (I/F), the impedance (Z) and inductance (L).
The ATIV™ will store up to 500 motor tests and test results can be sent to the provided computer software via the PC interface. The provided TREND™software offers analysis, trending and reporting for single and three phase AC induction motors.
Optional EMCAT PRO® software is available for analysis of DC motors and transformers.
The ATIV™ will test fractional horsepower motors to large synchronous machines and test measurement rules are well established and are easy to understand.
