Functional Features

• Metrological Verification: Supports on-site verification of the energy metering performance for AC charging piles.
• Comprehensive Error Detection: Capable of detecting operational error, energy display error, billing/payment error, and real-time clock accuracy on-site.
• Standard Compliance: Equipped with a standard charging interface compliant with GB/T 20234.2, ensuring compatibility with all types of AC charging piles.
• Multi-Parameter Measurement: Measures and displays AC voltage, current, power (P, Q, S), frequency, phase, power factor, and energy error.
• Harmonic & Alarm Functions: Supports 2nd to 50th harmonic content analysis. Features detection and over-limit alarms for energy display, transaction amounts, and clock errors.
• Automatic Status Diagnostics: Integrated function to automatically determine the connection status of connectors and cables.
• Automated Calibration: Equipped with RS232 and RS485 communication interfaces to interface directly with the charging pile, enabling the system to read energy values, billing limits, and current time for automated calibration.
• Daily Timing Accuracy: Includes a daily timing error test function and supports receiving second-pulse signals output by the charging pile.
• Rugged & Portable: Housed in a portable engineering plastic case with anti-shock and electrical protection, optimized for field environments.
• Real-world Load Simulation: Equipped with an adjustable physical load (impedance and power) to simulate authentic charging process conditions.
• Wireless Operation (Optional): Supports integration with an optional tablet computer for separated, remote operation, significantly enhancing safety and user convenience.
