Introduction Electromagnetic Pollution: Electromagnetic pollution refers to the interference of natural and man-made electromagnetic waves and harmful electromagnetic radiation. Due to the development of radio, television, and microwave technology, the power of radio frequency equipment has doubled, leading to increased electromagnetic radiation posing a direct threat to human health.
This table can be set to display the average measured value and the maximum average measured value.The maximum average measurement can be used as a directional test, for example when entering an exposed area for the first time. Detect the frequency range of 50MHz to 8GHz. Isodirectional electromagnetic field measurement.
三、Operating instructions 3-1 Front panel and button description (1).If the power off, press and hold button, until the LCD is on, then the unit will power on.If the power on, press and hold button, until the LCD is off then the unit will power off.

3-2 Main interface display content description 1. Represents the average measured value. 2. Represents the maximum average measured value.The initial interface only displays AVG, and the displayed value is the average value. Press the button, and MAX AVG will be displayed, and the displayed value is the maximum average value.

First of all, linear calibration, select linear, press button to enter linear calibration, there are three directions X, Y and Z optional, select X direction, press button to enter the calibration interface, ready to start calibration. Description: Calibration power value: Preset calibration power value. When calibrating, the standard environmental value should be adjusted to match the calibrated power value.The calibrated power values of y0-y7 are eight points, namely 0,1,2,5,10,20,50,100.Unit of V/m.

point. If there is a large difference, it needs to be calibrated; if there is a small difference, there is no need for calibration. After the linear calibration is completed, the frequency response is then calibrated.The wireless electromagnetic wave of this device measures the broadband power signal, and the measurement range is 50MHZ-8ghz.
(2)MAX AVG mode In AVG mode, users can press the function button on the right to switch to MAX AVG mode.In MAX AVG mode, the device calculates the maximum average data showing the X,Y, and Z axes.Users can press the function button on the left to save the current measurement results.The saved data can be viewed in the data record or on the computer via USB when the device is turned off.

Suggestion: Stabilize the table when measuring. 4-2 Short time measurement Maximum mode is used to determine the characteristics and direction of the unknown field when entering an electromagnetic field exposure area.It is very important to take several measurements at different locations around the area you want to measure, if you know nothing about the field.Pay special attention to making some measurements of nearby potential sources of radiation.Components other than radiation sources also emit electromagnetic fields.For example, electrical cables used in current diathermy medical devices may also emit...
