Multi functional three-phase phase voltmeter
Main indicators
>Voltage 0-500V>current 1.5mA-10A
>Phase 0-360 degrees>frequency 45-65Hz
>Accuracy level 0.5>Channel 3 voltage/6 current
Main features
1. Adopting a 3.4-inch LCD display, the interface display is clear and intuitive;
2. Measure and display three-phase voltage, current, phase, and hexagonal vector diagram; Real time measurement of active and reactive power, apparent power, frequency, and power factor for phase separation and total power;
3. Measuring phase with a small current of 1.5mA is very suitable for checking the connection status of newly installed users when there is no load after operation;
4. The instrument has high measurement accuracy and a wide measurement range of 5V~500V/1.5mA~Accurately measure phase within 10A range;
5. PT and CT transformation ratios can be set to automatically convert into primary side electrical parameters through secondary measurement;
6. Equipped with a 500A current clamp, it can measure current transformers, display angle difference, ratio difference, and distinguish polarity;
7. Automatically identify the load characteristics of the line, determine 1008 types of wiring errors in three-phase three wire and three-phase four wire electric energy meters, and indicate the location of the errors;
8. The measurement results can be displayed in various ways such as vector graphics and tables, with multiple parameters displayed on the same screen, making the measurement data clear at a glance;
9. Dual power supply: direct power supply for the measuring end and high-performance lithium battery power supply;
When powered by lithium batteries, the instrument can work continuously for 18-30 hours; Standby time ≥ 60 hours, charging times ≥ 500 times;
11. Built in memory, capable of storing 200 sets of measurement data, allowing access to saved data sets and vector graphs;
12. Automatic power saving management function, which can automatically shut down or enter sleep mode;
13. Built in clock chip, which can accurately record and display measurement time;
14. 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;
15. Optional VMP02 micro printer for on-site printing of measured data;
16. Implement browsing and querying functions for test results, combining Chinese menus with direct buttons for easy and user-friendly operation;
17. Built in help menu for easy on-site use and operation;
18. Humanized design, anti drop wristband to prevent operators from accidentally damaging the instrument;
19. Adopting an ultra small structural design, handheld, small in size, and lightweight.
Product Usage
1. Check the secondary circuit of the relay protection and the differential protection system, and read out the phase relationship between the CTs of each group of differential protection;
2. Automatically distinguish the positive and negative phase sequence of the line;
3. Multi parameter measurement of power lines (U/I/Φ/P/Q/S/PF/Hz);
4. Automatically determine whether the wiring of the electricity meter is correct or not;
5. Determine the speed of the electricity meter operation and collect electricity bills reasonably;
6. Can be used for household meter wiring testing, distinguishing between inductive and capacitive circuits;
7. Can be equipped with a high current clamp meter for power line loss management data collection;
8. Check the wiring group of the transformer;
9. Used as a leakage current meter, etc.
