The ALL-TEST Pro 5 (ATP5) has some fantastic features over the ALL-TEST IV PRO and the ALL-TEST Pro 33 including transformer, single phase and individual coil testing and trending. One of the unique features over the ALL-TEST IV PRO is that it will provide pass/warning/fail indications on the data collector and will also allow comparisons to prior tests. There are additional features which will be covered in future blogs.

The setup of the ATP5 for DC machines is extremely simple. As shown in Figures 3 and 4, there are a variety of DC motor types that can be selected including SV (Single Voltage) and DV (Dual Voltage), different types of DC motors (shunt, compound, series) and motor only or on a DC drive.
