High-Precision Single-Phase Meter Calibration: ZXDJ-1 Advantages

The ZXDJ-1 Single-Phase Energy Meter Calibrator represents a significant advancement in field calibration technology, offering 0.1-class accuracy and innovative features that distinguish it from conventional calibrators built around energy metering ICs. Designed for technicians who require reliable and efficient on-site calibration, this instrument combines high accuracy with user-friendly operation and robust data management capabilities.

A key differentiator of the ZXDJ-1 is its integrated simulated load function. Unlike traditional calibrators that require an external load, this device can generate a virtual load internally. This is particularly useful at sites where no actual load is available, greatly simplifying field testing of single-phase energy meters without compromising accuracy.

The calibrator supports comprehensive measurement of electrical parameters, including voltage, current, active power, and reactive power, with accuracy maintained across a broad operating temperature range (–20°C to +40°C). Notably, its performance varies based on the connection method: when using terminals, current measurement accuracy reaches 0.1% within 0.1A–10A, while with an optional clamp, it offers 0.3% accuracy from 0.1A to 60A and 0.5% up to 1000A. This flexibility allows technicians to handle both low-current direct connections and high-current applications with appropriate accessories.

Another standout feature is harmonic analysis up to the 51st order, with storage capability for all harmonic data. The device also includes a high-resolution 4.4-inch TFT color display for simultaneous presentation of settings, errors, parameters, and waveforms. Data from over 6,000 tests can be stored internally and exported via USB or RS232, supporting integration with PC-based management systems such as the PEC energy meter software for paperless operation.

The ZXDJ-1 employs a digital multiplier architecture with software-based calibration, eliminating physical potentiometers and enhancing long-term stability. Its wide input voltage range (AC 90–265V) and optional clamps (50A to 1000A) make it adaptable to diverse field conditions. Additional advantages include true reactive power measurement and a lightweight, durable housing.

In summary, the ZXDJ-1 calibrator offers a powerful, precise, and portable solution for single-phase meter verification, outpermany conventional devices through its virtual load technology, extensive data handling, and high accuracy under real-world conditions.
