1、 Functional Features

1Three voltage and three current vectors are displayed on the same screen. For complex differential protection devices, the double clamp method can be used for multiple measurements to finally draw a complete hexagonal diagram.

2Using clamp type current transformers for wiring, there is no need to disconnect the current circuit, which is safe and convenient.

3Vector analysis of complex protective devices can be performed to determine if the wiring is correct, and a correct wiring diagram can be provided for comparison.

4It can perform routine electrical parameter testing and display three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, and three-phase phase angle simultaneously; And it can directly read and convert the voltage amplitude, current amplitude, and power values to the primary side of the transformer.

5Can perform wrong wiring inspection for three-phase three wire high voltage metering devices, capable of detecting three-phase three wire faults48Analyze and judge the wiring, and directly provide the analysis results; Investigating and punishing malicious methods of electricity theft that alter metering wiring, effectively avoiding electricity bill losses.

6Can conduct harmonic analysis of the measured signal on site, capable of analyzing2－21Automatically calculate the total harmonic distortion based on the content of each sub harmonic.

7Large screen, high brightness color LCD display, fully Chinese character graphical menu and operation prompts achieve friendly human-machine dialogue, silicone touch buttons make operation more comfortable and feel better, LCD wide temperature and brightness adjustment, suitable for winter and summer environmental applications.

8Powered by a large capacity lithium battery, it can work continuously for up to8Hour.

9Users can save the test data in the form of records at any time for centralized and unified management, filing, and reference, and can store it1000Data above the group level.

10The saved records can be uploaded to the backend management computer for comprehensive analysis and review.

11Equipped with perpetual calendar and clock functions, it displays the date and time of the testing work in real time.

12Small size, light weight, easy to use on site.

13reserveUSBInterfaces can be used to replace portable storage devices such as USB drives with instruments.
