Technical Specfications:

         Product Features:

1. Integrated structure, small size and light weight. The instrument is highly integrated, which integrates nearly 

   one truck of equipment and equipment in the traditional main measurement method into the integrated main 

   chassis; it is the smallest and lightest of the domestic equivalent products; it provides a simple and 

   convenient way for the test Test means.

2. It is simple and convenient to access the power supply. All the measuring process of the instrument only

    needs to be connected to the 220V voltage of the commercial power supply, which solves the trouble of

    inconvenient access to the 380V voltage in the field in the existing measurement method.

3. Super resistance to induced voltage. The instrument uses a unique patented technology (patent number: 

    201020687669.X) anti-inductive voltage circuit to ensure that the instrument can withstand a higher induced

    voltage (anti-inductive current can reach 40A) and can work normally at a high induced voltage of 10,000 volts .

4. Frequency conversion technology and accurate measurement. Strong anti-interference ability, the instrument's 

    own variable frequency power supply module provides instrument measurement output power, the frequency can

    be changed to 45Hz and 55Hz, and the digital filter technology is used to effectively avoid various industrial

   frequency interference signals on the spot, so that the instrument achieves high Accurate, accurate and reliable measurement.

5. High-speed processor. Accurate and fast, the instrument uses a professional fast digital signal processor as the
    processing core. Under the premise of ensuring the accuracy of the measurement data, it greatly improves its
    own arithmetic processing ability.

6. Simple operation. The external wiring is simple, and the positive sequence impedance, zero sequence impedance, positive

   sequence capacitance, and zero sequence capacitance only need to be connected to the down line of the tested line once at

   the test end to complete all the measurements; the existing test methods are solved Wiring switching is troublesome, 

   anti-interference, stability, accuracy and other aspects of the problem; to avoid damage to the experimental personnel 

   due to the induced voltage when changing the wiring.

7. Mass data storage. The instrument is equipped with a calendar chip and a large-capacity memory, which can save the 

   test results in chronological order. You can view the historical records at any time and print them out.

8. Scientific and advanced data management. The instrument data can be exported via U disk, and the data can be viewed 

   and managed on any PC and can be used as a work report.

9. Operation safety protection. The instrument is specially designed to detect the grounding function to determine whether

  the instrument is well grounded on the site. If the grounding is falsely connected or not connected, the instrument will

   automatically judge, prohibit the operation of the user, ensure personal safety, and protect the use of the instrument.

10. Full touch large LCD display. The operation is simple, the instrument is equipped with a high-end full-touch LCD display,

   and all operation steps of the large display interface are displayed in the Chinese menu. Each step is very clear, and the

  operator can use it without additional professional training. The whole process of measurement can be completed with 

  one touch, and it is currently an ideal intelligent measurement device.
