The cabinet houses voltage source, small signal source, current source, main control unit, and industrial control computer display unit. It can output 0~1000V DC voltage, 0~100A DC current, 0~5V small signal, achieving incremental output for energy meter calibration. Voltage accuracy is 0.02 level, current accuracy is 0.05 level, and energy accuracy is 0.1 level; the hanging table body is mainly used for meter position fixing, including meter racks and table body, with six meter positions, capable of simultaneous calibration of 6 energy meters.

Main Functions

• The shell is made of special aluminum alloy material, beautiful and elegant, structurally strong, lightweight, and easy to transport.
• Uses a dedicated junction box 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 device has an independent PC and common calibration point shortcut keys, enabling quick setting of commonly used test parameters during manual meter calibration, making manual calibration more convenient.
• Equipped with 485 communication port function, facilitating easy reading and modification of data inside multifunction meters, capable of reading or automatically setting communication addresses for each meter position. (Optional)
• The device has comprehensive testing functions with a dedicated wiring clamp; once the output ports of the meter under test are connected, it can automatically complete tests such as active energy and daily timing error.
• Fully automatic inspection of energy meter start-up, creep, and basic errors according to regulations.
• Direct large current output (0~100A), indirect current (0~5V), fully designed according to DC energy meter specifications, compatible with calibration or performance testing of various DC meters.
• Voltage and current can each superimpose 20~500Hz ripple, with adjustable ripple amplitude and phase maintained in phase.
• Can calibrate energy meters with different constants and has constant verification function.
• Dedicated photoelectric sampler can collect LED light pulse signals from electronic meters.
• Dedicated pulse sampling interface with high-voltage isolation circuit to prevent high-voltage misconnection.
• Can perform dial test according to energy, time, or pulse count.
• Has power-based meter calibration function, can directly read power measurement values of the meter under test via 485 bus interface and calculate errors.
• Can display parameters such as power, voltage, current, and ripple.
• Supports PC connection with dedicated calibration software featuring a user-friendly interface and simple calibration settings; allows manual addition and setting of any calibration points, with data storage and printing capabilities.
• Has automatic detection of communication protocols, compliant with all agreements of DL/T 645-2007, and can modify communication agreements according to user requirements. (Optional)
• Supports barcode input for convenient meter information entry. (Requires barcode scanner)
• Equipped with clock reference, supports daily timing error testing of energy meters.
• Supports self-heating test, can perform self-heating influence test on the meter under test and provide error variation curves. (Optional)
• The device uses single-phase power supply for user convenience.
• The polarity connection of DC meter current positive and negative can be program-controlled switched, facilitating indirect meter access; through program control, the corresponding shunt and voltage short-circuit wires can be directly shorted to prevent damage to the energy meter.
• Each meter position has automatic and manual switching capabilities, allowing users to select meter positions participating in calibration; users can easily switch positions via software selection.
• Supports barcode information scanning input for the meter under test; scanned information is automatically associated with the meter.
