A compact, lightweight and high-stability tester with large-screen graphical LCD and Chinese menu interface. It measures positive-sequence, zero-sequence, impedance, power and other parameters in one screen, with simple wiring and easy operation.

1. Measures positive-sequence, zero-sequence, phase-to-phase, line-to-ground parameters, voltage, current, active and reactive power.
2. Supports external voltage and current transformers for extended range measurement.
3. Wide voltage range up to 750V with single-range high accuracy, no gear switching needed.
4. Large high-brightness LCD with Chinese prompts and adjustable backlight for all seasons.
5. Built-in high-speed micro thermal printer for real-time test data printing.
6. Equipped with RS232 port for computer communication and data centralized management.
