Problems solved by technology

[0002] For the measurement of power frequency electromagnetic fields, the current domestic use is a single-dimensional field strength measuring instrument, and the power frequency electric field and the power frequency magnetic field cannot be measured and displayed synchronously at the same time, and only the power frequency electric field meter can be used to measure the power frequency electric field. The power frequency magnetic field meter measures the power frequency magnetic field, and the power frequency electric field meter or the power frequency magnetic field meter cannot measure the radio frequency field at the same time; for the radio frequency field measurement, the radio frequency field strength meter or microwave energy leakage meter is mainly used, which has low measurement accuracy and small range. The frequency band is narrow, and the radio frequency field strength meter or the microwave energy leakage meter cannot measure the power frequency electromagnetic field at the same time

[0003] In addition, in the detection process of the current measurement tools, the measurement personnel first need to determine the frequency band detected in the environment, and then select the probe or instrument suitable for this frequency band detection, and finally the measurement personnel need to rotate the probe in the environment to obtain the maximum electromagnetic field component. This leads to cumbersome measurement, high labor intensity, and low detection efficiency; and it may affect the reliability of the measurement data due to the actual detection environment and the human factors of the user.
