HF-MT-506 Single Phase Energy Meter Tester

Product Overview

HF-MT-506 Hand‑held Single‑Phase On‑site Energy Meter Tester is designed for on‑line accuracy and function testing of single‑phase energy meters. It measures energy, power, current, voltage, power factor and meter error and calibrates constants without power cut‑off or wire disconnection. It can store data of up to 2000 meters and supports data query & management.

Adopting a 32‑bit ARM embedded system with graphic menu display, accuracy adjustment can be completed via keystrokes for improved reliability and stability. Compact, lightweight, fully‑featured and user‑friendly, it is an ideal instrument for on‑line inspection of single‑phase energy meters.
