Main features
1. 5.7-inch large screen color LCD display, with clear and intuitive interface display. Hexagonal vector diagram color separation display, with Chinese prompts for positive and negative phase sequence;
2. Can be used to detect the wiring group of transformers, test secondary circuits and bus differential protection systems;
3. Multiple measurement methods to choose from, capable of measuring secondary circuit wiring (Y/Y, Y/△, Y/Y/△) for both two and three coil transformers, displaying various phase relationships of three-phase voltage, six channel current for two coil transformers, and nine channel current for three coil transformers on the same screen;
4. Two loop transformer measurement: Display three-phase voltage and six channel current input signals on the same screen, and display multiple phase relationships between three-phase voltage and six channel current on the same screen at the same time. Automatically calculate vector rows (differential current), vector angles, data tables, and dual channel vector graphs;
5. Three loop transformer measurement: It can measure the high, medium, and low-end current values and angles (IAH, IAM, IAL) of phase A, the high, medium, and low-end current values and angles (IBH, IBM, IBL) of phase B, and the high, medium, and low-end current values and angles (ICH, ICM, ICL) of phase C. It can automatically synthesize and calculate the vector sum (differential current) and vector angle data table and vector graph of 9 high, medium, and low-end currents;
6. Power parameter measurement: Real time measurement of frequency, power factor, active and reactive power, as well as the phase separation and sum of apparent power;
7. Without connecting voltage signals, the phase relationship of six current channels can be directly measured;
8. Vector diagram drawing can freely set the X-axis, Y-axis, 12 points, 11 points, and 3 points, which conforms to various wiring methods;
9. Dual power supply：Exchange PT measurement terminal power supply and lithium battery power supply. Lithium batteries can work continuously for 10 hours, with a standby time of ≥ 40 hours and a charging frequency of ≥ 500 times;
10. Automatic power saving management function, which can automatically shut down or enter sleep mode;
11. Built in memory, capable of storing 200 sets of measurement data, allowing access to saved data sets and vector graphs;
12. Built in clock chip that can accurately record and display measurement time;
13. Vector calculator, which can facilitate users to calculate the sum of voltage and current vectors;
14. Instrument measurement data can be grouped and uploaded to a PC to enable browsing, querying, reporting, and printing of test results;
15. Optional VMP02 micro printer, capable of on-site printing of measured data;
16. Chinese menu combined with direct buttons, easy to operate and use;
17. Handheld, small in size, light in weight, anti drop wristband to prevent operators from accidentally damaging the instrument;
18. The background color can be selected from white/black/blue/dark blue, with the factory standard being dark blue.
