The GF438II Class A handheld three-phase power quality analyzer comes with built-in 32G large-capacity TF storage, automatically storing all measured data including harmonic records, flicker trend curves, three-phase unbalance logs, power statistics and voltage sag/swell event records during on-site testing. Users can quickly browse historical measurement records directly on the 640×480 color touch screen, filter data by test time, parameter types and fault thresholds, and view complete trend graphs and statistical tables without connecting external devices.
Equipped with high-speed USB communication interface, the instrument supports one-click batch export of all stored data to U disk, compatible with GFUVEPQA dedicated PC analysis software. After data export, engineers can conduct offline deep secondary analysis, customize power quality reports, export data in standard formats for archiving and client submission. Besides USB, it also integrates Ethernet port to realize remote data transmission and real-time cloud monitoring for long-term grid inspection projects.
All measurement data can be stored at user-defined recording intervals, supporting up to 600 monitoring parameters for continuous long-term logging. Lightweight portable design and over 6 hours of battery runtime make it ideal for field inspection of photovoltaic stations, wind farms, industrial distribution networks and utility power grids, greatly simplifying post-test data sorting and report generation workflows.
