Advanced AC Sampling Calibrator: ZX3030E
In the field of electrical power testing and calibration, precision, versatility, and efficiency are paramount. The ZX3030E Multifunction AC Sampling Calibration Device represents a significant technological step forward, integrating advanced digital signal processing and high-precision conversion to meet diverse calibration needs. This article provides a technical overview of the ZX3030E, highlighting its key features and performance metrics, with comparisons to traditional calibration methods for context.
Core Technology and Design Philosophy
The ZX3030E is built around a powerful Digital Signal Processor (DSP) core and high-accuracy A/D and D/A converters. This architecture ensures stable output and precise measurement, a foundational improvement over older calibrators that often relied on less integrated or analog-heavy designs. Unlike traditional setups requiring separate standard meters for validation, the ZX3030E is an all-in-one source and measurement unit, simplifying the workflow for calibrating indicating instruments, energy meters, transducers, and AC sampling devices.
Key Performance Characteristics and Comparative Advantages
High Accuracy and Class: The device achieves a comprehensive error of 0.05%, surpassing many conventional calibrators which might be limited to 0.1% or lower classes. Its voltage and current output accuracy is also 0.05% (with a minor exception for the 100mV DC range at 0.1%), ensuring highly reliable reference signals and measurements. In contrast, simpler calibrators often struggle to maintain such accuracy across wide ranges and under varying loads.
Wide Range and Auto-Ranging: The ZX3030E offers extensive AC/DC voltage and current ranges. For instance, AC voltage spans from 15V to 600V automatically, and AC current covers 0.05A to 25A. This auto-ranging capability, coupled with a fine adjustment resolution of 0.002% of the nominal value, provides flexibility and precision that manual range-switching older units lack. It can directly drive capacitive loads up to 1µF on the 100V range, demonstrating robust output capability.
Multi-Function Output and Analysis: A standout feature is the ability to output and measure power, frequency, phase, power factor, and harmonics (up to the 31st order, with odd-order restrictions beyond the 11th). This makes it suitable for testing modern electronic meters and protective relays under complex, non-sinusoidal conditions—a task for which traditional calibrators without harmonic generation capability are ill-suited.
Automation and Connectivity: Equipped with PC software and wireless communication modules, the ZX3030E enables automated calibration, remote testing (especially beneficial for AC samplers in switchyards), data management, and report generation. This contrasts sharply with fully manual calibrators, which are slower, prone to human error, and lack data traceability features. The large LCD with intuitive Chinese menus further enhances operational ease.
Stability and Reliability: The device boasts excellent stability (≤0.01% per minute for V, I, P) and high phase accuracy (±0.2°). It has undergone rigorous environmental and stress testing (overload, vibration, misuse, high-temperature aging), ensuring dependable operation in demanding field or lab conditions—a level of robustness not always guaranteed in older or less meticulously designed equipment.
