Description:

This meter assessment solution is capable of evaluating mechanical, electromechanical, and electronic meters through fully automated, semi-automated, or manual processes.
It is designed for testing single-phase meters with a 1P2W configuration.
The system offers testing for true power, reactive power, and zero-sequence reactive power.
Incorporating MSVT technology, it can examine single-phase meters with integrated current and voltage circuits (I-P links).
An optional current output switch facilitates the calibration of two-component meters.
It enables the concurrent assessment of meters that share identical specifications but possess varying constants.
The system features automated alignment of the mechanical meter's rotor mark for enhanced operational efficiency.
Capable of performing start-up tests and slow-movement assessments.
Equipped with safeguards against excessive load, low-voltage shorts, and open-circuit conditions.
The synchronized movement of scanning heads streamlines the control process.
Constructed from aluminum alloy for a lightweight, robust, and corrosion-resistant design.
The user-friendly software is compatible with Windows 2000/XP/7/8/10 and encompasses a comprehensive suite of modern energy meter testing functionalities, including error analysis, harmonic analysis, load profiling, and impact assessments.
