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.
