How to use the electromagnetic wave radiation detector
Introduction to Electromagnetic Radiation
Electromagnetic waves (also known as electromagnetic radiation) are waves that move in space in the form of electric and magnetic fields that oscillate in phase and are perpendicular to each other. Their propagation direction is perpendicular to the plane formed by the electric and magnetic fields, effectively transferring energy and momentum. Electromagnetic radiation can be classified by frequency, from low to high, including radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays, and so on. The electromagnetic radiation that can be received by the human eye, 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.
usage method
1. Press the "power switch" for a short period of time to turn on the device, and it 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 without relaxing, and after about two seconds, switch to 'electric field radiation intensity' detection.
Attention: This instrument is a high-precision measuring instrument. Due to the influence of the Earth's magnetic field, the instrument may occasionally experience very brief numerical displays or alarms, which is not a fault phenomenon.
2. Hold the electromagnetic radiation detector in your hand, align the "testing area" with the object to be tested, and slowly move closer to the object until you actually come into contact with it. The closer you get to the object to be tested, the stronger the electromagnetic field 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 test item is turned off during the measurement, the reading should return to zero in the "magnetic field radiation intensity detection" mode; In the "electric field radiation intensity detection" mode, some objects can still detect electromagnetic wave signals, which belong to the external electromagnetic wave signals received by the object and are not harmful to the human body.
5. Press the 'Alarm Settings' button briefly to set the alarm sound to turn on and off.
6. Pressing the 'peak lock' button briefly can set the peak lock function to be turned on and off. The peak locking function can lock the maximum value during the detection process.
