GF438II Long-Term Trend Recording & PST/PLT Flicker Measurement

 Built around IEC 61000-4-15 flicker international standards, the GF438II handheld power quality analyzer independently calculates short-term PST (10-minute) and long-term PLT (2-hour) flicker values for three-phase and neutral circuits, eliminating manual timing and calculation work for inspectors. It continuously captures voltage fluctuation data, generates intuitive flicker trend curves, and automatically marks time nodes where flicker exceeds standard limits for rapid grid interference source identification.

Its advanced long-term trend logging engine supports custom sampling intervals ranging from seconds to hours, capable of continuously storing up to 600 types of electrical indicators in the built-in 32G TF storage for weeks of unattended monitoring. All tracked metrics include voltage/current RMS, unbalance ratio, harmonic distortion, power values and flicker data, which are rendered into continuous trend charts with zoom and cursor tools for later data review. The system automatically retains complete timestamp labels for every record, fully meeting EN50160 grid compliance audit requirements.

Distinct from basic testers that separate flicker testing and trend storage, this unit synchronizes flicker sampling and long-term data recording in one single run without repeated test setup. The flexible 4-channel voltage and 4-channel current input design supports simultaneous flicker monitoring across multiple load branches, ideal for field audits of manufacturing workshops, photovoltaic combiner boxes and municipal power supply lines. After on-site testing, all trend and flicker datasets can be exported via USB to the matching GFUVEPQA PC software to generate standardized power quality compliance reports with embedded flicker trend graphs.

GF112D Simple Wiring for Single-phase Meter Inspection

 The GF112D adopts an integrated clamp design to achieve extremely simple wiring during single-phase meter inspection. Engineers only need to clip the current clamp onto the target circuit without cutting off cables or modifying existing wiring connections.

Complicated wiring terminals and extra auxiliary leads are minimized, greatly lowering the threshold for field operation and reducing risks of misconnection. Fast setup shortens preparation time for each inspection task, enabling technicians to carry out batch single-phase watt-hour meter verification efficiently in residential and commercial power sites.

The simplified connection scheme effectively improves inspection efficiency and guarantees safe operation in compact distribution box environments.

Complete Using Tutorial for GF211D Portable Phase Voltmeter

The GF211D digital phase meter features comprehensive environmental adaptability to handle complicated testing surroundings ranging from outdoor open-air substations to damp underground mining workshops. It operates steadily within -10°C to +50°C and tolerates non-condensing humidity between 5% and 95%, without accuracy drift under temperature fluctuation. High input impedance for voltage channels avoids signal attenuation on thin secondary wiring, while magnetic shielding inside the dual current clamps suppresses interference from surrounding inverters and heavy motors. Users can utilize the built-in data hold function to lock transient abnormal electrical signals for analysis. The complete shockproof portable storage case neatly holds the main unit, clamps, insulated cables and documents, convenient for vehicle transportation and frequent site transfers between multiple construction sites.
