1. Three-channel voltage and six-channel current vectors are displayed on the same screen; for the test of differential protection devices, only one wiring is required to complete the drawing of the hexagonal diagram, which greatly improves the work efficiency; in the case of small space and difficult wiring, it can also Use the double-clamp method to make multiple measurements to draw a complete hexagonal graph.

2. The clamp-type current transformer is used for wiring without disconnecting the current loop, which is safe and convenient.

3. Vector analysis of complex protection devices can be performed to determine whether the wiring is correct, and the correct wiring diagram is given for comparison.

4. It can carry out conventional electrical parameter test, and display three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, three-phase phase angle; and can directly read the voltage amplitude converted to the primary side of the transformer, The value of current amplitude and power.

5. The three-phase three-wire high-voltage measuring device can be checked for wrong wiring, and the 48 types of three-phase three-wire wiring can be analyzed and judged to directly give the analysis results; investigate and deal with the malicious stealing of the metering wiring to effectively avoid the loss of electricity charges.

6. Harmonic analysis of the measured signal on the spot can be carried out, each content of the 2nd to 32th harmonic can be analyzed, and the total harmonic distortion can be calculated automatically.

7. Large-screen, high-brightness color LCD display, full English character graphical menu and operation prompts realize friendly human-machine dialogue. Touching the silicone buttons makes the operation comfortable and feels good. The wide-temperature LCD with brightness adjustment can adapt to winter and summer seasons.

8. Large-capacity lithium battery power supply, continuous work for up to 6 hours.

9. The user can save the test data in the form of record at any time for centralized and unified management, record and inspection, and can store more than 2000 sets of data.

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

11. With perpetual calendar and clock function, real-time display the date and time of test work.

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

13. The USB interface is reserved, and instruments can be used to replace USB flash drives and other mobile storage devices.
