Button functions and settings

1. Power on/off/Alarm
Switch on and off: long press to turn on, in the next long press to turn off.
Note : The alarm is on by default, if you think the alarm sound is too noisy, press this button to turn off the power on/off/alarm. Press this button to hear the alarm when you need a reminder. If you do not want to use the meter, press and hold the button for a few seconds and the meter will turn off.

2. ELEC (Electric Field Intensity) Standard Frequency Mode
Press ELEC to select the electric field intensity mode, the meter will display Standard Frequency Response and V/M symbol. The default power-on measurement is the electric field strength mode. The electric field strength measurement function is mainly used to measure the electromagnetic radiation emitted by electric wires,electric lights, wall sockets, electrical switches and ungrounded appliances at a frequency (40Hz- 100kHz). In the electromagnetic environment of a quiet home or office, the electric field strength should be less than 50V / M

3. W-ELECcElectric Field Strength) Weighted Frequency mode
Press W-ELEC to select electric field weighted frequency mode, the meter will display Weighted Frequency Response and V/M symbol.
The electric field strength measurement function is mainly used to measure the electromagnetic radiation emitted by electric wires, electric lights, wall sockets, electrical switches and ungrounded appliances. The measurement frequency should be greater than 60 Hz.higher frequencies will produce more radiation damage in the body. For example, at 60 Hz, the body receives 60 electric field pulses per second, while at 120 Hz, the body receives twice as many electric field pulses, or 120 per second. Although the electric field remains the same, the damage to the body is twice as great as at 60Hz. In the electromagnetic environment of a quiet home or office, the electric field strength should be less than 50V / M.

4. MAG (Magnetic Field Strength) Standard Frequency Mode
Press MAG to select the magnetic field strength mode, the meter will display the Standard Frequency Response and mG symbol. The magnetic field strength measurement function is used to measure the magnetic field radiation emitted by electric motors, appliances, wires and power lines. The measurement frequency is 40~200Hz and should be less than 4.0mG in low magnetic field environment.

5. W-MGA (Magnetic Field Strength) Weighted Frequency Mode
Press W-MGA to select the magnetic field weighted frequency mode, the meter will display Weighted Frequency Response and the mG symbol. The magnetic field strength measurement function is mainly used to measure the magnetic field radiation emitted by electric motors, appliances, wires and power lines, the measurement frequency should be greater than 60 Hz. higher frequencies will produce more radiation damage in the human body.

6. RF (Radio Frequency Measurement) Functions
Press RF to select RF mode, and the meter will display mW/m². It is mainly used to measure high-frequency radiation near cell phones and wireless transmission routers, cell towers, microwave ovens, smart meters, wireless landlines or walkie-talkies, and wireless TV stations. Measurement band 20MHz~6GHz. It can measure video signals of current standard 4G and 5G (RF bandwidth from 600MHz to 6GHz).
The field measurement data of a radio-silent area should be less than 0.200mW/m².

7. MAX (Maximum Value Function) Applicable to ELEC, MAG, W_ELEC and W_MAG Measurement Functions.
Press the MAX to activate the MAX function. The meter will display the MAX symbol. The meter will display the maximum value of the electric or magnetic field measurement.

PEAK (peak function) it is only used for RF function
Press the PEAK to activate the PEAK function. The meter will display the PEAK symbol.
The signals sent by cell phones, routers, etc. are sent in pulses, and the PEAK function captures the maximum signal within 5 seconds. So the PEAK function can accurately measure the maximum radiation generated by cell phones, routers, etc.The peak measurement data of a radio silent area should be less than 1.000 mW/m².

The Standard and Weighted Modes

The Standard modes for AC magnetic fields (MAG) and AC electric fields (ELEC) will measure fields using a flat frequency response. That is, all frequencies from 40 Hz to 100 kHz (100,000 Hz) are measured with equal sensitivity. The Weighted modes for magnetic fields (W-MAG) and electric fields (W-ELEC) measure 60 Hz fields with the same sensitivity as the Standard mode. However, the Weighted modes are more sensitive at frequencies higher than 60 Hz, and from 60 Hz to 500 Hz, sensitivity increases proportional to frequency. That is, 1milligauss (mG) at 60 Hz will read “1.0” on the display, whereas 1 mG at 120 Hz will read “2.0”.

See the frequency response curves on page 12 for more detail. On Weighted modes, the Field Measurement shows a number proportional to the average electric current induced inside the human body from the fields, and the number is equivalent to the amount of 60 Hz magnetic or electric field that would be required to induce that much current. However, biological reactions generally occur at speeds that are slower than 1000 Hz, so on Weighted modes, the meter is designed to become less and less sensitive at frequencies above 1000 Hz.

EMF EXPOSURE LIMITS

Many different EMF exposure limit standards have been published. Below is a table of some of the published national and international standards. There are many variables that determine the basis of these standards, including: EMF frequency, length of exposure, and affected body part(s). One thing to note is that the IEEE and most Western European limits are based on the thermal impact of EMF on the human body, whereas the Russian and Eastern European limits focus more on dose over extended exposure periods. For more detail, the sources are listed below.

Typical Home and Office EMF Levels

The maximum exposure limits shown above are much higher than levels you would typically encounter. Some authorities recommend much lower levels for long- term exposure, but as yet there is no consensus on safe levels. Generally, when measuring homes or offices, only the actual areas where people spend time (or where EMF-sensitive equipment is to be located) are important. In the middle of a typical home or office, magnetic field is usually less than 5.0 mG, electric field is usually less than 20 V/m, and RF is usually less than 5.000 mW/m2.
