1. Low frequency electromagnetic radiation detector: detection of magnetic materials, detection of geomagnetic fields, monitoring of electromagnetic environment radiation in subways, 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: field strength measurement for industrial furnaces, welding systems, RF heating, tempering and drying equipment, heat transfer equipment and medical equipment (NMR), RF transmission devices, sensitive areas (hospitals, schools), radio communication systems, mobile communication base stations, broadcasting stations, and TV transmission tower environments.

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. After about two seconds, switch to 'electric field radiation intensity' detection

2. Hold the electromagnetic radiation detector in your hand, align the "test 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 measure the object 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 for a short period of time can set the peak lock function to be turned on and off. The peak lock function can lock the maximum value during the detection process
