Six way differential protection wiring tester
Product Details
Main indicators
>Voltage 0-500V>current 2mA-10A
>Phase 0-360 degrees>frequency 45-65Hz
>Accuracy level 0.5/0.2 >Channel 3 voltage/6 current
>Phase 0-360 degrees>frequency 45-65Hz
>Accuracy level 0.5/0.2 >Channel 3 voltage/6 current
Main features
1. Adopting a 5.7-inch large screen color LCD display, the interface display is clear and beautiful;
2. Display three-phase voltage, six current, phase relationship, and vector diagram on the same screen; Real time measurement of active, reactive, and apparent power, including phase separation and total power, with multiple phase relationships displayed. Vector graph color separation display is more intuitive;
3. Two loop transformer measurement: Display three-phase voltage and six current input signals on the same screen, and display multiple phase relationships between three-phase voltage and six current on the same screen at the same time. Automatically calculate vector sum (differential current), vector angle data tables, and display double vector graphs;
4. Without connecting voltage signals, the phase relationship of six current channels can be directly measured;
5. The vector diagram display can be set with X and Y axes, 12 points, 11 points, and 3 points, which comply with various wiring methods;
6. Calculate the sum of high and low current vectors (differential current) and display the vector angle;
7. Dual power supply: The AC measurement terminal can be directly powered by 55V-450V, or it can be powered by a built-in lithium battery;
8. Power automatic power-saving management function, which can automatically shut down or enter sleep mode;
9. Built in clock chip, which can accurately record and display measurement time;
10. Vector calculator, which can conveniently calculate the sum of voltage and current vectors using rows;
11. 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 standard EXCEL format files and generate experimental reports;
12. Built in memory, capable of storing 200 sets of measurement data, allowing access to saved data sets and vector graphs;
13. Implement browsing, querying, reporting, and printing functions for test results;
14. Chinese menu combined with direct buttons, easy to operate and use;
15. Handheld, small in size, light in weight, anti drop wristband to prevent operators from accidentally damaging the instrument;
16. The background color can be selected from white/black/blue/dark blue, with the factory standard being dark blue;
17. Optional voltage isolation channel can be used to measure transformer wiring group or grid connected phase.
