Main functions

7-inch (800 * 480) TFT true color LCD display, graphical user interface, touch screen operation；
Online measurement of three-phase voltage, current, frequency, active power, reactive power, apparent power, and power factor for phase separation and total power, and display of multiple phase relationships of electrical U-U, U-I, and I-I；
The measurement results can be displayed in various ways such as vector graphics and tables, with over 20 parameters displayed on the same screen, making the measurement data clear at a glance；
The current measurement limit can be used as a leakage current meter to measure zero sequence current;
Automatically identify the load characteristics of the line, check 48 types of three-phase four wire and 96 types of three-phase three wire connections, display the secondary wiring diagram and power expression, and provide Chinese prompts for positive and negative phase sequence；
Load curve recording and load fluctuation monitoring function: It can dynamically monitor the adjustment and operation process of power equipment, and record and store power parameters such as voltage, current, active power, reactive power, apparent power, frequency, phase, etc；
PT/CT setting, can convert secondary data into primary data；
Calculation of voltage and current imbalance；
Vector calculator, on-site calculation of voltage and current vector sum；
Built in standard Chinese character library, using Pinyin Chinese character input method to input Chinese characters/letters/numbers and other stored content；
Dual power supply: measurement terminal power supply and high-performance lithium battery power supply. The lithium battery can work continuously for 10 hours when powered；
Automatic power saving management function, which can automatically shut down or enter sleep mode；
Built in memory, capable of storing 5000 sets of measurement data, allowing access to saved data sets and vector graphs；
Support data uploading to computers, allowing for direct browsing, export, editing, printing (A4 format), backup, and other functions of instrument data. It can also be exported as a standard EXCEL format file and generate experimental reports；
The instrument is equipped with a USB interface, which can be used to download working parameters or transfer measurement data through a USB flash drive；
The instrument is equipped with an RS232 interface, which can be connected to a computer to achieve real-time data transmission function；
Optional micro printer for on-site printing of measured data；
Handheld, small in size, light in weight, anti drop wrist guard to prevent operators from accidentally damaging the instrument；
The APP online data collection system software includes multiple functional sections such as data collection, data query, upload/download, trend analysis, and imbalance analysis;
Trend analysis function: Automatically draw voltage/current/power trend charts, displaying maximum/minimum/average values;
Unbalance analysis function: automatically draw an imbalance curve chart, displaying the maximum, minimum, and average values;
Data can be uploaded/downloaded and sent to other technical personnel through WeChat or QQ via the network for remote data analysis;
Wireless transmission and communication function: Bluetooth wireless+intelligent APP dedicated software enables data collection, storage, viewing, and analysis on Android handheld terminals;
Tablet terminals and handheld devices have a large amount of data storage, including voltage, current, phase, power, power factor, vector graphics, geographic location, photos, and a large amount of on-site testing data;
The dedicated APP system software has strong applicability and is suitable for all Android phones. It has a graphical Chinese interface, touch operation, and supports Chinese character input, making the application more user-friendly and easy to operate;
The APP application software based on Android handheld terminals has more powerful functions and is also used for investigation and evidence collection functions (such as photography and location).
The APP online data collection software is upgraded for free for life.
