User Guide

For Radio/Microwave (RF) frequencies (cell phones, WiFi routers,
microwave ovens, and radio/tv stations), turn the knob to RF.
Note that the brief pulses sent by transmitting cell phones and WiFi
routers will be displayed in the peak measurement in the upper left
corner of the LCD. A Radio quiet area will typically have less than
1.000 milliwatts per square meter as a peak. The field measurement
numbers should read less than 0.200 milliwatts per square meter.
For Electric (ELEC) Fields (fluorescent lights, wall outlets and
wiring, and electrical switches), turn the knob to Standard ELEC
or Weighted ELEC. In an electromagnetically quiet home or office,
both Standard and Weighted ELEC will read less than 50 V/m.
Frequently Asked Questions
Do I measure on Standard or Weighted or both?
Both. Standard MAG or ELEC measures the strength of the field regardless of
frequency (40Hz-100kHz). Weighted MAG or ELEC emphasizes the higher frequencies
above 60Hz. Higher frequencies will create more electric current inside the human body.
For example, at 60Hz, the body is receiving field pulses 60 times per second, while at
120Hz, the body is receiving twice the number of pulses, or 120 times per second,
though the field remains the same.
What is a ‘safe’ level?
Absolute safe levels have not been established. However, according to our research,
there have not been problems associated with staying below:
3mG Standard Magnetic or 5mG Weighted Magnetic
50 V/m Standard or Weighted Electric
0.200 mW/m² RF (field measurement) or 1.000 mW/m² (peak measurement)
Exposure Levels mentioned here are typical readings taken from homes and offices
that are relatively low in total electromagnetic fields. Legal maximum exposure levels
are MUCH higher than the levels described above. Some practitioners may
recommend somewhat different levels.
When do I use Magnetic (MAG), Electric (ELEC) or Radio (RF)?
Typical magnetic fields are emitted by motors, appliances, wiring and power lines.
Electric fields are emitted by power lines, lights, wall outlets, electrical switches, and
ungrounded appliances. RF is found near transmitting cell phones and wifi routers, cell
phone towers, microwave ovens, smart meters, wireless landline phones or walkie
talkies, and radio/tv stations. Power company smart meters only pulse about once per
minute. Watch for the peak number.
In order to reduce exposure, avoid high-field areas or use shielding. Each type of field
has simple, specific shielding techniques (see online guide).
