Data Sheet DM-II Plus Power Quality Recorder Amprobe's DM-II PLUS is a full-featured three phase power quality recorder to maintain, diagnose and troubleshoot electrical systems. It measures and records a broad spectrum of power quality parameters. Easy to use, it's capable of measuring and recording voltage, current, voltage anomalies (sags or surges), harmonics, energy and power (active, reactive and apparent), power factor (true and displacement), and frequency. This unique product comes as a complete kit with current transducers and an increased memory size for data storage, larger display size, and real-time downloading using Amprobe's unique Download Suite software. No hassle warranty No waiting. AC No shipping charges. All Our commitment to high-quality products and customer service is demonstrated by our industry exclusive "No Hassle" warranty. In the unlikely event that an Amprobe Test Tool requires warranty service, any of our local dealers are authorized to replace it, on the spot. Current up to 1000A, AC Voltage, Active, Reactive and Apparent Power, Energy, Peak Demand & Power Factor readings are True RMS 5 built-in selectable languages: English, French, Italian, German and Spanish User selectable rates allow recording from one hour to several months Works with single & three phase systems (Y & delta) Readings and charts can be viewed on the DM-II LCD screen or downloaded to a PC Capable of recording all parameters (single or three phase) simultaneously Optional transducers available for 100A and 3000A (flexible) current capability.
