The method of use of the electromagnetic wave radiation detector
Introduction to Electromagnetic Radiation
Electromagnetic waves (also known as electromagnetic radiation) are waves that move in space through in-phase oscillations and perpendicular electric and magnetic fields. Their propagation direction is perpendicular to the plane formed by the electric and magnetic fields, effectively transmitting energy and momentum. Electromagnetic radiation can be classified according to frequency, from low frequency to high frequency, including radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays, and so on. The electromagnetic radiation that the human eye can receive, with a wavelength of approximately 380 to 780 nanometers, is called visible light. Any object with a temperature greater than absolute zero can emit electromagnetic radiation, and there is no object in the world with a temperature equal to or lower than absolute zero.
1. Press the "power switch" briefly to turn on the device, which defaults to "magnetic field radiation intensity" detection. If it exceeds 2 milligauss, an alarm will sound; Press and hold the "detection mode switch" for a long time, and after about two seconds, switch to "electric field radiation intensity" detection.
Attention: This instrument is a high-precision measuring instrument. Due to the Earth's magnetic field, the instrument may occasionally display very brief numerical values or give an alarm, which is not a fault phenomenon. EMF detector is a portable health and safety field detector, which can detect AC magnetic field, electric field and high-frequency (RF) radiation. It is mainly used to detect and evaluate the impact on human body of non-ionizing electromagnetic field, magnetic field and high-frequency radiation in living and working environment.
2. Hold the electromagnetic radiation detector in your hand, align the "testing area" with the object to be tested, and slowly move close to it until you actually come into contact with it. The closer you get to the object to be tested, the stronger the electromagnetic or electric field will increase, and the faster the alarm frequency will be.
3. In measurement, trying to change the angle and position of the instrument to the object being measured can obtain the maximum reading value.
4. If the power of the tested item is turned off during measurement, the reading value should return to zero in the "magnetic field radiation intensity detection" mode; In the "electric field radiation intensity detection" mode, certain items can still detect electromagnetic wave signals, which belong to the external electromagnetic wave signals received by the item and are not harmful to the human body.
5. Press "Alarm Settings" briefly to set the alarm sound on and off.
6. Press "Peak Lock" briefly to set the peak lock function on and off. The peak locking function can lock the maximum value during the detection process. This EMF detector is a portable healthand safety field detector, which can detect AC magnetic field, electric field and high-frequency (RF) radiation. It is mainly used to detect and evaluate the impact on human body of non-ionizing electromagnetic field , magnetic field and high-frequency radiation in living and working environment.
WIDE RANGE OF APPLICATIONS Suitable for use with household appliances operating in the power frequency range, such as refrigerators, washing machines, dishwashers, vacuum cleaners, electric blankets, televisions, personal computers, and ultrasonic generators.
