Main functions
1. 7-inch (800 * 480) TFT true color LCD display, graphical operation interface, can be operated by touch screen or manual button operation, the interface display is clear and intuitive;
2. Measure the phase separation and total power of three-phase voltage, current, frequency, active power, reactive power, apparent power, and power factor online, and display multiple phase relationships of electrical U-U, U-I, and I-I;
3. 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;
4. The current measurement limit can be used as a leakage current meter to measure zero sequence current;
5. 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;
6. Load curve recording and load fluctuation monitoring function: online real-time monitoring of electrical parameters such as voltage, current, active power, reactive power, apparent power, frequency, phase, etc;
7. PT/CT settings can convert secondary data into primary data;
8. Calculation of voltage and current imbalance;
9. Vector calculator, on-site calculation of voltage and current vector sum;
10. Built in standard Chinese character library, using Pinyin Chinese character input method to input Chinese characters/letters/numbers and other stored content;
11. Dual power supply: The measuring end is directly powered and the high-performance lithium battery is used for power supply. The instrument can work continuously for 10 hours when powered by the lithium battery;
12. Automatic power saving management function, which can automatically shut down or enter sleep mode;
13. Built in memory, capable of storing 5000 sets of measurement data, allowing access to saved data sets and vector graphs;
14. Support data uploading to computers, allowing for direct browsing, exporting, 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;
15. 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;
16. The instrument is equipped with an RS232 interface, which can be connected to a computer to achieve real-time data transmission function;
17. Optional micro printer for on-site printing of measured data;
18. Handheld, small in size, light in weight, anti drop wrist guard to prevent operators from accidentally damaging the instrument;
19. Optional voltage isolation channel can be used to measure transformer wiring group and grid connected phase.
Product Usage
1. Check the secondary circuit wiring of the relay protection and bus differential protection system, and read the phase relationship between each group of CTs;
2. Check the wiring of the secondary circuit of the electric energy billing system;
3. Automatically detect the wiring of the electricity meter/household meter to determine the speed of the meter operation and collect electricity fees reasonably;
4. Automatically distinguish the positive and negative phase sequence of the line;
5. Multi parameter measurement of power lines (U/I/Φ/P/Q/S/PF/Hz);
6. Measurement of electricity quality in the power grid;
7. Load curve recording and online monitoring of load fluctuations;
8. Discrimination of load characteristics between inductive and capacitive circuits;
9. Check the wiring group of the transformer;
10. Used as a leakage current meter, etc.
