It is built in a compact cabinet that contains a multi-position carrying/tilt handle and a rear plastic snap-on cover for cable storage and transportation in the shop or field. The "M" is the perfect choice for your complete preventive/predictive maintenance testing - DC Hi-Pot testing, handheld resistance meter* testing and the capability of testing fully assembled grounded motors without rotating the rotor position. With PJ's High Frequency Technology, the entire windings of each phase can be surge tested to detect weak and damaged insulation, all with the convenience of a 3 Phase Transfer Switch. View your results on the digital storage oscilloscope and then print out your waveforms within seconds** or download data to your PC / laptop utilizing the USB device port or store it directly on the USB Flash drive.
