Product Description

Advanced Meter Test System for Power & Energy Meters

General Features

Supports measurement of active/reactive power and energy with high accuracy
Automatic color marking for fast diving and start-up testing
Measures basic error, average error, standard deviation, and 24-hour variation
Can test multiple meters with same voltage/current but different constants simultaneously without circuit decoupling
Includes current open-circuit detection, automatic short-circuit protection, voltage fault detection, and optional temperature module
Automatic error data processing, storage, and online output via software
Flexible report generation with barcode input and database download support
Modular design with one-time wiring and automatic crimping for efficient operation
Multi-protocol RS485 server ensures smooth communication and protocol conversion

Special Functions

Time period switching, demand cycle, freeze function, and timing error testing
Meter display and combination error verification
Four-quadrant reactive power and error consistency testing
Optional dual circuit test for anti-tampering meters
Dynamic power, load variance, charge control, and residual power accuracy tests
Performance tests including overload, overvoltage, tilt impact, infrared, Bluetooth, and carrier wave
Advanced harmonic analysis meeting IR46 standards for sharp/flat top waves and various harmonics calibration
