Introduction to handheld electromagnetic radiation detector
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.
Measurement steps of electromagnetic field tester (Gauss meter)
1) Turn the "Off/Range" switch to the corresponding position, select the maximum gear for unknown measurement situations, and then lower it again to achieve the highest accuracy. Due to electromagnetic interference in the environment, it is normal for the instrument to display small values before measurement.
2) Slowly move the handheld instrument towards the tested object until it touches it. Note that the reading increases as you move
3) Point the instrument at different angles to the measured object and observe the change in reading.
4) Try measuring from different angles and record the maximum value. If the power supply of the measured object is turned off during the measurement process, the tester reading will return to "0". 5) The measurement unit of the instrument is microTesla. If you want to know the value of milli Gauss, please multiply the reading by "10".
6. It is recommended to regularly check the electromagnetic radiation inside and outside your home. If strong radiation points are found, please relocate the environment.
7) When "LO BAT" is displayed in the upper left corner of the LCD, it indicates that the battery voltage is between 6.5V and 7.5V, and the battery needs to be replaced. However, the battery can still be used for a few hours thereafter. Remove the battery cover and replace it with a new 9V battery. Cover the lid back.
