Product Features

1. No power off, no change to the measurement circuit, and no opening of the measurement equipment, the comprehensive error
   of the online real-load detection measurement equipment (including energy meter, CT, wiring error).

2. It can detect the comprehensive error of the measuring device (including the basic error of the electricity meter, the error of the
    transformer and the wiring error), the basic error of the electricity meter, the CT transformation ratio and various electrical parameters.

3. Measure voltage, CT primary and secondary current, power, power factor and other electrical parameters, so as to accurately
   analyze and judge the fault of the measuring equipment loop

4. Measure the current of CT primary and secondary side, so that the transformation ratio and error of current transformer can be measured.

5. The current loop is measured with a clamp transformer, and the operator can measure conveniently and safely without disconnecting
   the current loop. The limit of the clamp transformer is 15A.

6. Voltage circuit automatic switching limit: the voltage circuit is automatically judged by the internal circuit to the range of the input voltage
   and switched to a suitable gear at any time. There will be no damage to the instrument itself due to the test voltage exceeding the limit.

7. When one phase of voltage or current clamp is reversed (that is, the power is negative), the analyzer automatically alarms (loudspeaker sounds).

8. The calibration data is stored for a long time, and the calibration data of 200 tables can be stored at a time. The user can view and delete it
    by pressing the button at any time; also can communicate with the computer through the 232 serial port, upload the data, and use the
    special background software The form is saved for easy unified management.

9. True clock function, you can check the current date (including week) and time (accurate to seconds) at any time.

10. Large-screen, high-brightness LCD display, equipped with Chinese menu prompts to achieve friendly man-machine dialogue, LCD brightness
     can be adjusted by buttons, can adapt to the impact of different seasons on the LCD.
