OVERVIEW Introduction The TriField® EMF Meter is an AC gaussmeter, AC electric field meter, and radio power density meter in a single unit, that combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). In addition to standard AC measurement modes, a special frequency weighted mode will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body.
USING THE TRIFIELD EMF METER 1. Hold the meter as shown. Note: Please do not cover the sensors at the top of the meter with your hand or other objects. 2. The knob is used to switch between measurement modes and to turn the meter off when not in use. 3. For measuring the effect of EMF on the human body (or any conductive body), use the dark blue Weighted modes. For direct measurement of field strength, use the light blue Standard modes.
Reading the LCD The Field Measurement shows the numerical measurement and units, at the bottom of the LCD. The Field Measurement is averaged to give the most stable, accurate reading possible. The Field Percentage Indicator shows a circular bar graph of the percentage of maximum range that corresponds to the Field Measurement, on a logarithmic scale. The Field Percentage Indicator has a scale that shows tick marks for 0, 10, 20, 50 and 100 percent of maximum range.
The AC Magnetic Mode uses three ferrite-core coils, pointing in the X, Y, and Z directions, located near the top of the meter. The X, Y and Z signals are combined into a true magnitude of the field strength, independent of which direction the meter is pointed. Maximum range is 100.0 mG, with resolution of 0.1 mG, and accuracy of ±4% of reading at 50 Hz and 60 Hz. A frequency response graph of Standard and Weighted modes is on page 7. In most homes or offices, some areas are “hot” spots with high readings.
RF and Microwave Field Detection To measure an RF field, turn the knob to the RF setting and point the top of the meter at the potential source, or simply hold the meter vertically. Generally, your hand can shield the RF signals, so grip the meter as shown on page 2. The RF Mode uses the same plate sensor as the AC Electric Mode. The signal is amplified and converted to a power density magnitude, calibrated at a frequency of 1 GHz (1000 MHz). Maximum range is 19.999 mW/m2 with resolution of 0.
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.
