Available Configurations

The MPRT8445 incorporates the latest in Digital Signal Processor (DSP) and microprocessor-based technology, to provide a powerful, easy to use relay test set. The unit can be operated either manually via hand held controller or placed under full computer control via the AVTS, Advanced Visual Testing Software. The hand held controller, called the Smart Touch-View InterfaceTM (STVI), is Megger’s second generation of handheld controllers. It incorporates a large, easy to read Full Color high resolution, high definition, TFT LCD touch-screen display, which displays metered values such as AC and DC Amperes, AC and DC Volts, and Time in both seconds and cycles. Depending on the type of test selected, other values may be displayed, such as Ohms, Watts, Phase Angle, or Frequency.
