Advanced Hand-Held Three-Phase Meter Calibration: Introducing the ZXDN-3001

In the field of electrical testing and calibration, accuracy, efficiency, and portability are crucial. The ZXDN-3001 Hand-held Three-phase Electricity Meter Calibrator represents a significant step forward compared to traditional bench-top calibrators and basic handheld testers. Designed for field and laboratory use, this device integrates multiple functions into a single lightweight instrument, offering technicians a powerful tool for meter verification, electrical parameter measurement, and power quality analysis.

Unlike conventional calibrators that often require disconnecting current circuits or using multiple instruments, the ZXDN-3001 allows for non-intrusive measurement via clamp-type current transformers, enabling safe and efficient real-load testing without power interruption. Its ability to perform online error verification under live conditions sets it apart from older systems that necessitate de-energizing panels or using additional test fixtures.

Key technical capabilities include:

1.High-accuracy measurement of voltage (0–450V), current (25A/500A via clamps), active/reactive power, phase angle, power factor, and frequency.

2.Integrated vector diagram display with automatic wiring diagnosis for three-phase three-wire systems (48 wiring modes detected).

3.Power quality analysis covering harmonics, voltage fluctuations, frequency deviation, and three-phase unbalance.

4.Support for multiple calibration methods: photoelectric, manual, and pulse-based  electricity meter verification.

5.Data logging and PC communication for traceability and reporting.

With a accuracy class of 0.2/0.5 for active parameters and 0.5/1.0 for reactive power, the ZXDN-3001 matches or exceeds the performance of many stationary systems, while its hand-held form factor (1.8kg, compact design) enables easy transport and operation in constrained spaces. The color LCD with intuitive English GUI further enhances usability for technical personnel.

In comparison to older generation calibrators, which often lack power quality features or require external transformers, the ZXDN-3001 provides an all-in-one solution, reducing setup time and potential errors. Its robust design (-20°C to +50°C operating range) and dual power options (internal battery or AC supply) ensure reliability in diverse field conditions.

For technicians involved in meter calibration, grid maintenance, or energy auditing, the ZXDN-3001 offers a versatile, precise, and efficient tool that simplifies complex measurement tasks and supports data-driven decision making. Its combination of high accuracy, comprehensive analysis, and portability makes it an ideal choice for modern power system testing.
