MULTI-FIELD EMF-54 Multi Field EMF Meter
OVERVIEW
EMF detector is a portable health and safety field detector, which can detect AC magnetic field, electric field, and high-frequency (RF) radiation.

SPECIFICATIONS
USE THE METER
-
Power On/Off
Press the “ ” key to turn on the power; Press and hold for about 1 second to turn off the power. -
Auto power off
When the power is turned on, the display shows “ ” symbol. Without any key operation, the meter will auto-power off after about 15 minutes. -
Cancel auto power off
Press and hold the “HOLD” key, then press the “ ” key to turn on the power, then release the “HOLD” key, and the “ ” symbol on the display disappears. The auto power-off function is canceled. Turn on the power again, and the auto power off function will resume. -
Alarm tone on or off
Press “ ” key to tum on or off the alarm tone -
Max measurement
Press the “MAX” key to start the maximum memory, Press the “MAX” key again to return to normal measurement. -
Data Hold
Press the “HOLD” key to turn on or off the display lock.
Measurement function selection
Press the “FUNC” key to select the magnetic field (uT), magnetic field (mG),
electric field (V/m), and RF (mW/m2) functions.
LCD
The measured value is the average of the field measurements to obtain the most
stable and accurate reading possible. The trend graph is a rapid response to
the changing trend of field measurement.
The peak value is the maximum peak value measured and maintained for about 3
seconds or until a larger peak value is measured.
Measurement operation
Note: Do not cover the sensor on the top of the meter with hands or other objects during measurement.
AC Magnetic Field Detection
- Press the “ ” key to turn on the meter power.
- Press the “FUNC” key to select the “ ” magnetic field uT or mG measurement function.
- Hold the meter (as shown above) and keep the top of the meter at the position to be measured.
- When the measured value is<0.12uT (1.2mG), the display will light green.
- When the measured value is<0.40uT (4.0mG), the display will light orange.
- When the measured value is.::0.40uT (4.0mG), the display will light red.
- Read the measurement results from the display.
In the magnetic field mode, it can be measured in any direction, because the
magnetic field is measured in the 3-axis mode, pointing to the X, Y, and Z
directions, and is located near the top of the instrument. The X, Y, and Z
signals are combined into an actual field strength.
Most homes or offices have several areas with high magnetic field readings.
These magnetic fields mainly come from unmatched internal wiring, displays,
fluorescent lamps, dimmers, transformers, electric blankets, heaters, or other
equipment with motors in electrical equipment.
AC Electric Field Detection
- Press the “ ” key to turn on the meter power.
- Press the “FUNC” key to select the “ ” electric field measurement function.
- Hold the meter (as shown above) and keep the top of the meter at the position to be measured.
- When the measured value is<40V/m, the display will light green.
- When the measured value is<400V/m. the display will be light orange.
- When the measured value is.::400V/m, the display will light red.
- Read the measurement results from the display.
Note: Do not cover the sensor on the top of the meter with hands or other objects during measurement.
Your body is easy to shields the electric field; If you cover the surface of the meter with your hand, the measured value will be lower. The presence of your hand at the bottom of the meter will compress the electric field, making its reading slightly higher than when the meter is hanging away from you. In either case, the real electric field near the meter will be displayed. Most households or offices have several areas with high electric field readings. These electric fields mainly come from the area of incorrectly grounded equipment, the front of video displays fluorescent lamps, etc.
RF and Microwave Field Detection
- Press the “ ” key to turn on the meter power.
- Press the “FUNC” key to select the “ ” RF field measurement function.
- Hold the meter (as shown above) and keep the top of the meter at the position to be measured.
- When the measured value is<10mW/m2 the display will light, green.
- When the measured value is<50mW/m2, the display will light orange.
- When the measured value is.:: 50mW/m2, the display will light red.
- Read the measurement results from the display.
Note: Do not cover the sensor on the top of the meter with hands or other objects during measurement.
Your body can easily block RF signals; If you cover the surface of the meter
with your hand, the reading will be lower.
RF and microwave are made up of a special combination of electric and magnetic
fields. For frequencies below about 100MHz, the main impact on the conductor
is only from the magnetic field. This is because the electric field component
of the radio wave generates a much weaker current in the body than the
magnetic field unless the wavelength of the radio wave is less than the height
of the body.
When reading the RF emitted by digital devices (such as mobile phones and smart meters), PEAK peak measurement (the number in the middle of the display) is more concerned. Because signals from digital RF equipment are irregularly short sent in packets.
Peak measurement PEAK detects these signals and displays the strongest signal for about 3 seconds.
Replace the batteries
When the “ ” symbol is displayed on the display screen, it means that the battery is low. Please replace the battery in time.
Typical home and office EMF level
Generally, when measuring the home or office, only the actual area where
people spend their time (or the area where EMF-sensitive equipment is located)
is important. In a typical home or office, the magnetic field is usually less
than 0.50uT (5.0 mG), the electric field is usually less than 20 V/m, and the
radio frequency is usually less than 5.000 mW/m2.
Disclaimers
The use of the meter is entirely up to the user to decide whether to be exposed to non-ionizing electromagnetism. The user needs to use it to measure the known reference value to determine whether the meter works normally. The test data of this meter is for reference only, and the manufacturer or dealer will not bear the damage caused by inaccurate existing knowledge of the meter or electromagnetic potential health hazards. A meter should be used to take simple steps (such as moving furniture or radiation source equipment) to reduce relative exposure in the home or office. If more accurate testing is required, it is recommended to consult experts or use another type of meter for accurate testing.
