Product Introduction

XL-9100T18 DC Energy Meter Calibration Device Built-in 18 independent voltage sources and 1 current source, capable of outputting 0~1500V (MAX: 1725V) DC voltage and 0~100A DC current, enabling incremental output for the calibration of direct DC energy meters. Voltage accuracy is 0.02 level, current accuracy is 0.03 level, and energy accuracy is 0.05 level; designed with a dedicated meter rack with 18 slots, allowing simultaneous calibration of 18 direct energy meters (0~100A).
 

Main Features

• The enclosure is made of special aluminum alloy material, elegant and sturdy in structure, lightweight, and easy to transport.
• Equipped with a dedicated meter rack for convenient meter calibration.
• High-quality linear power amplifier with low ripple output and good stability.
• Multiple protection systems with audible and visual alarm functions for higher reliability.
• The operation software includes shortcut keys for common calibration points, allowing quick setting of frequently used test points during manual meter calibration, making manual calibration more convenient.
• Equipped with RS485 communication port, capable of communicating with the tested DC meter to read electrical parameters.
• Fully automatic testing of meter start, creep, basic error, daily timing error, constant test, etc., according to regulations.
• Supports ripple influence test; voltage and current can superimpose 10~500Hz ripple, with ripple factor and phase adjustable as needed.
• Dedicated pulse sampling interface with high-voltage isolation circuit to prevent high-voltage misconnection.
• Supports power-based meter testing function, can directly read the power measurement value of the tested meter via 485 bus interface and calculate error.
• Can display parameters such as power, voltage, current, and ripple.
• Supports PC connection; dedicated calibration software has a user-friendly interface and simple, intuitive calibration settings. Users can manually add and set any calibration points, with data storage and printing capabilities.
• Equipped with GPS clock reference, supporting daily timing error testing of energy meters.
• Supports self-heating test, allowing self-heating influence experiments on the tested meter and providing error variation curves.
• The device uses single-phase power supply for user convenience.
• Each slot has automatic and manual switching capabilities, allowing users to select slots participating in calibration easily via software.
• Supports barcode information scanning input for the tested meter; scanned information automatically associates with the tested meter (requires additional barcode scanner).
• Equipped with 220VAC, 12VDC, 24VDC auxiliary power interfaces, adjustable ±20%, enabling power drop tests for energy meters.
