8 Introduction Meter Overview Powerful Multifunction Power Meter The Acuvim II series multifunction digital power meter is designed using modern MCU and DSP technology. It integrates three-phase energy measuring and displaying, energy accumulating, power quality analysis, malfunction alarming, data logging and network communication. A vivid LCD display with large characters and, time of use programmable backlight provides a clear realtime data readout. An Ideal for Electric Automation SCADA Systems The Acuvim II series meter is the ideal choice for replacing traditional, analog electric meters. In additon to providing clear real-time readings on the meter front, it can also be used as a remote terminal unit (RTU) for monitoring and controlling for a SCADA system.

9 Users can access all measurement parameters via the standard RS485 communication port (or the optional Ethernet port) with the ModbusTM protocol. Energy Management The Acuvim II series meter is able to measure bidirectional, four quadrants kWh and kvarh. It provides maximum/minimum records for power usage and power demand parameters. All power and energy parameters can be viewed remotely via software in order to easily monitor various parameters. In addition, measurement tables can be viewed from the free Acuview software. Remote Power Control This meter is designed for measuring and monitoring power quality parameters. Since different I/O modules can be added to the meter, this expands the capabilities and provides a very flexible platform for using the meter as a distributed RTU, for metering, monitoring and remote controlling, all in one unit.

10 Acuvim II Series Power Meter Chapter 1: Introduction Revised October 2018 10 Power Quality Analysis Utilizing digital signal processing (DSP) technology, the Acuvim II series meter provides high accuracy power quality analysis and supports remote monitoring via the Ethernet module. The meter continuously updates metering results and allows users to access the meter online to monitor parameters such as voltage and current THD, harmonics, voltage crest factor, current K factor, and voltage and current unbalance factor etc. Data Logging The Acuvim IIR/IIE/IIW meter contains 8 megabytes of onboard memory for data logging and historical trending. Since the meter contains a real-time clock, all events and logged data will be time stamped.
