  • High-Speed Capability for Permanent Installation

    Designed for permanent installations, Multipoint performs just like the portable Power Recorder simultaneously measuring all power quality parameters, as well as power consumption and harmonics. The system consists of a detachable acquisition unit and a base that manages connections to your power system.

    Full Disclosure Technology is included with Multipoint, making it a unique, professional tool that increases your ability to maintain and troubleshoot your plant’s power quality.

    Read more about Full Disclosure technology in the Multipoint Power Recorder® datasheet.

  • Multipoint features:



    • 2 MS/s sampling system for capturing and viewing high-speed events as fast as 500 ns
    • 4 voltage channels – three phases plus neutral-to-ground. Measure up to 600 Vrms, 1000 Vpeak
    • 5 current channels allow you to monitor neutral and ground current in addition to phases designed to connect to industry-standard 5-amp CT’s. Also available with connections for clamp-on CT’s
    • Measurement system docks with a permanently-mounted base, allowing calibration or service without having to shut down power
    • Capture up to 6,000 simultaneous voltage events with simultaneous current, in each monitoring session
    • Multi-session option allows for 16 sessions, effectively multiplying event capture capability to 96,000 events
    • 128 samples per cycle -- on every cycle at 50 or 60 Hz
