Product Mode Overview

AC Magnetic Field Detection

Press the "" key to switch to the "MAG" magnetic field uT or mG measurement function.

Illustration:

1. The orientation of the meter does not affect magnetic mode readings, as all three axes are combined. The AC Magnetic Mode utilizes three ferrite-core coils positioned at the top of the meter, pointing in the X, Y, and Z directions. The X, Y, and Z signals are combined to provide the true magnitude of the field strength, regardless of the meter's orientation.
2. You can expect to find areas with elevated magnetic field readings in most homes or offices. These fields primarily emanate from unshielded internal wiring, video displays, fluorescent lights, light dimmers, transformers within consumer devices, electric blankets, heaters, and any equipment with a motor.

AC Electric Field Detection

Press the "" key to switch to the "ELEC" electric field measurement function.

Illustration:

1. Your body can easily shield electric fields; the reading is lower if you cover the top surface of the meter with your hand.
2. Your hand at the back of the meter compresses the electric field, making it read somewhat higher than if the meter were suspended from a string or held on a board away from you. The true electric field near the meter will be displayed in either case.
3. There are several areas in most homes or offices with high electric field readings. These fields originate primarily from improperly grounded equipment, the front of video displays, and areas of fluorescent lighting.

RF and Microwave Field Detection

Press the "" key to switch to the "RF" high-frequency measurement function.

Illustration:

1. Your body can effectively shield RF signals; covering the meter's face with your hand will result in lower readings.
2. When measuring RF emissions from digital devices like mobile phones and smart meters, the Peak Measurement (displayed as small numerals in the middle of the screen) is more relevant than the Field Measurement (shown as large numerals at the bottom). Digital RF devices transmit data in short, irregular bursts. The Peak measurement identifies and displays the strongest signal for approximately 3 seconds.

Visual & Audible Alarm

Visual Alarm

Audible Alarm

Short press the "" button to turn on or off the audio alarm. The icon will be displayed on the screen when turning on the sound. The meter will be alarmed when the measured value reaches the "slight" level. The intensity and frequency of sound changes according to the measured value.

Typical EMF Levels for Home & Office Environments

The following information provides an overview of typical electromagnetic field (EMF) levels in home and office environments. It is important to note that the maximum exposure limits mentioned below are significantly higher than you would typically encounter. While some authorities recommend lower levels for long-term exposure, there is no consensus on universally safe levels. When measuring EMF levels in a home or office, it is essential to consider the areas where people spend their time or where EMF-sensitive equipment is present.

Magnetic Fields: In the central areas of a standard home or office, magnetic field levels are typically below 0.50 uT (5.0 mG). These levels are considered to be within the normal range of radiation exposure.

Electric Fields: Within the same central areas of a typical home or office, electric field levels are typically less than 20 V/m. These levels are generally regarded as being within the acceptable range of radiation exposure.

Radio Frequencies: Radiofrequency levels in a typical home or office environment are typically below 5.000 mW/m². These levels of radiation are generally considered to be within safe limits.

Please note that the above information is a general guideline and may not account for specific variations in EMF levels within individual spaces. Following any specific guidelines or regulations provided by local authorities or relevant governing bodies regarding EMF exposure is always recommended. If you have any concerns or questions about EMF levels in your home or office, it is advisable to consult with a qualified professional or seek further information from authoritative sources.
