GF438II Basic Electrical Data Statistics & Automatic Logging Function

 The GF438II handheld Class A power quality analyzer embeds an independent statistical calculation module that continuously computes real-time, maximum, minimum and average values of core electrical indicators throughout the whole monitoring cycle, covering voltage, current, frequency, active/reactive power and power factor across all four voltage and four current channels. Unlike ordinary testers that only display instantaneous readings, it automatically accumulates statistical data without manual trigger, enabling engineers to quickly grasp load fluctuation ranges without post-processing on a PC.

Users can freely customize logging cycles from short second-level sampling to long-hour intervals to match different field test scenarios. All statistical datasets are timestamped and saved to the built-in 32G TF card synchronously, supporting long unattended recording lasting multiple days. The on-device statistical dashboard arranges all calculated values in intuitive tabular layout, and supports quick screen scrolling to compare peak and valley data of each phase, simplifying on-site preliminary evaluation of load stability.

Its logging system runs parallel with other test modes including harmonic analysis and flicker detection, so basic statistical records will not be interrupted when switching measurement functions. After field work completes, all stored statistical logs can be exported via USB drive and imported into GFUVEPQA PC software for data sorting, comparative analysis and standardized report generation. Equipped with a long-lasting rechargeable battery and compact lightweight body, it is well-suited for regular power inspection of factories, commercial buildings, new energy power stations and municipal power supply lines.

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.
