The DM-4 addresses the needs of the most demanding Power Quality professionals. The device incorporates full set of measuring features crucial for complete Power Quality analysis. An innovative Remote User Interface (PDA) allows safe, easy and convenient operation of the device remotely. The Remote User Interface (PDA) is also used for data viewing, analysis and transfer. Independently, the DM-4 can be used directly with the PC type of computer. Since the DM-4 does not have any control buttons on its enclosure, it is protected against setup changes by unauthorized persons while the device is recording.
