The Standard and Weighted Modes
Use Weighted modes for magnetic fields (W-MAG) and electric
fields (W-ELEC), short press W/℃/℉ to switch 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 9 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 in
Weighted modes, the meter is designed to become less and less
sensitive at frequencies above 1000 Hz.
