How to use an electromagnetic radiation detector?
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
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 lock function can lock the maximum value during the detection process
Introduction to types of electromagnetic radiation detectors
1. Low frequency electromagnetic radiation detector: detection of magnetic materials, detection of geomagnetic field, monitoring of electromagnetic environment radiation in subway, monitoring of AC and DC high-voltage transmission and transformation systems, monitoring of workplaces such as distribution rooms, computer rooms, and sensitive instrument rooms.
2. High frequency electromagnetic radiation detector: Measurement of field strength in industrial furnaces, welding systems, radio frequency heating, tempering and drying equipment, permeable equipment and medical equipment (NMR), radio frequency transmission devices, sensitive areas (hospitals, schools), radio communication systems, mobile communication base stations, broadcasting stations, and television transmission tower environments.
