Multi functional dual clamp digital phase voltmeter
Main indicators
>Voltage 0-500V>current 5mA-10A or 1mA-5A
>Phase 0-360 degrees>frequency 25-65Hz
>Accuracy level 1.0>Channel 2 voltage/2 current
Main features
1. The host adopts a 65X50 LCD display screen with high brightness backlight, displaying 3 sets of data on one screen, and the interface is intuitive and clear;
2. Direct function key operation, automatic range switching without shifting gears;
3. Measure the true effective value of voltage and current, as well as various phase relationships of U-U, U-I, and I-I. Real time measurement of electrical parameters such as active power, reactive power, apparent power, power factor, and frequency;
4. The voltage and current dual channel symmetrical design is mutually insulated, which can detect the wiring group of the transformer. When measuring the U-U phase value, the two voltage input circuits are insulated and isolated, which will not cause a short circuit in the measured line or burn out the instrument;
5. The current amplitude and phase characteristics are flat, and the phase can be accurately measured within the range of 5mA-10A;
6. Equipped with a pointed nose clamp shaped current transformer, it has high measurement accuracy and strong anti-interference ability, making it particularly convenient to use in situations with dense wiring;
7. Powered by lithium batteries, the backlight can work continuously for 18 hours when turned off, and for 8 hours when turned on, with a low power indicator;
8. Built in memory, capable of storing 60 sets of measurement data and allowing access to saved data sets;
9. Optional data management software can be used to upload measurement data to a PC, automatically draw vector diagrams, and print inspection reports;
10. The instrument is equipped with a print output interface and can be equipped with a micro printer VMP02 to print detection data online;
11. The instrument has an automatic power-saving management function, which automatically recognizes the working status, does not shut down during operation, and can automatically shut down when no one is using it;
12. The instrument is simple to use and easy to operate, making it very suitable for use as a tool for wiring discrimination, measurement competitions, and teaching instruments in various power schools;
13. Ultra small streamlined structure, anti drop wristband design, handheld, small size, light weight.
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. Check the wiring of the electricity meter/household meter to determine the speed of 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. Discrimination of load characteristics between inductive and capacitive circuits;
7. The voltage and current channels are completely isolated and can be used for grid connected phase inspection;
8. Check the wiring group of the transformer;
9. Used as a leakage current meter, etc.
