Introduction

This document provides operating, maintenance and installation instructions. These units measure and display the characteristics of single phase two wires (1p2w), three phase three wires (3p3w) and three phase four wires (3p4w) networks. The measuring parameters include voltage (V), frequency (Hz), current (A), power (kW/kVa/kVar), import, export and total Energy (kWh/kVarh). The units can also measure Maximum demand current and power, this is measured over preset periods of up to 60 minutes.
