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 off-line 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
