1 E201 Meter Quick Start Guide
This meter has many capabilities, including memory,
alarm, date/time, average etc. which will require some
study of the manual to use properly. However, you can
quickly and easily begin making measurements right
out of the box. Just follow these simple steps:
•Insert 9V battery
•Press the “ ” button to turn on the meter.
•Press XYX/MEM button until all three (XYZ)
letters are displayed on the screen (to the left of the
main number)
•Press UNIT/ENTER “” button until the desired
units are displayed below the main number (we
recommend using mV/m… and we recommend a
maximum level of 614 mV/m for prolonged
exposure).
You are now ready to make your first measurements!

2 Introduction
Thank you for purchasing the E201 Wide Range RF
Field Strength Meter from Anaheim Scientific. This
meter is designed for measuring and monitoring Radio–
Frequency electromagnetic field strength. Compact,
durable and easy to use.
2.1 The E201 Features:
•The meter is a broadband device for monitoring
high-frequency radiation in the range from 10MHz to
8GHz.
•The non-directional electric field antenna and high
sensitivity also allow measurements of electric field
strength in TEM cells and absorber rooms.
•Reports electrical and magnetic field strength and
power density. At high frequencies, the power
density is of particular significance. It provides a
measure of the power absorbed by a person
exposed to the field. This power level must be kept
as low as possible at high frequencies.
•The meter can be set to display the instantaneous
value, the maximum value measured or the average
value. Instantaneous and maximum value
measurements are useful for orientation, e.g. when
first entering an exposed area.
•For (non-directional) isotropic measurements of
electromagnetic fields with three-channel
measurement sensor.
•High dynamic range due to three-channel digital
results processing.

•Configurable alarm threshold and memory function.
•Easy & safe to use.
•Low battery indicator “ ”.
•Manual data memory storing: 200 data sets.
•Memory over load indication “OL”.
2.2 E201 Applications:
•High frequency (RF) electromagnetic wave field
strength measurement
•Mobile phone base station antenna radiation power
density measurement
•Wireless communication applications (CW, TDMA,
GSM, DECT)
•RF power measurement for transmitters
•Wireless LAN (Wi-Fi) detection, installation
•Spy camera, wireless bug finder

4 EMF Safety
•In some cases, work in the vicinity of powerful
radiation sources can be life threatening.
•Be aware that persons with electronic implants (e.g.
cardiac pacemakers) are subject to particular
dangers in some cases.
•Observe the local safety regulations of the facility.
•Observe the operating instructions for equipment
which is used to generate, conduct, or consume
electromagnetic energy.
•Be aware that secondary radiators (e.g. reflective
objects such as a metallic fence) can cause a local
amplification of the field.
•Be aware that the field strength in the near vicinity of
radiators increases proportionally to the inverse
cube of the distance. This means that enormous
field strengths can result in the immediate vicinity of
small radiation sources (e.g. leak in wave guides,
inductive ovens)
•Field strength measuring devices can underrate
pulsed signals. Particularly with radar signals,
significant measurement errors can arise.
•All field strength measuring devices have a limited
specified frequency range. Fields with spectral
components outside of this frequency range are
generally incorrectly evaluated and tend to be
underrated. Before using field strength measuring
devices, you should thus be certain that all field
components to be measured lie in the specified
frequency range of the measuring device.

9 Fundamentals
9.1 Electromagnetic Pollution
This meter is used to indicate electromagnetic pollution
generated artificially. Wherever there is a voltage or a
current, electric (E) and magnetic (H) fields arise. All
types of radio broadcasting and TV transmitters
produce electromagnetic fields, and they also arise in
industry, business and the home, where they affect us
even if our sense organs perceive nothing.
9.2 Electric Field Strength (E)
A field vector quantity that represents the force (F) on
an infinitesimal positive test charge (q) at a point
divided by that charge. Electric field strength is
expressed in units of volts per meter (mV/m). This
meter measures electric field strength directly.
9.3 Magnetic Field Strength (H)
A field vector that is equal to the magnetic flux density
divided by the permeability of the medium. Magnetic
field strength is expressed in units of amperes per
meter (A/m). In far field situations, one can calculate
the magnetic field using the electric field value. This
meter can display the calculated magnetic field
strength.

9.4 Power Density (S)
Power per unit area normal to the direction of
propagation, usually expressed in units of Watts per
square meter (W/m2) or, for convenience, units such as
milliwatts per square centimeter (mW/cm2).
9.5 The Characteristic of Electromagnetic
Fields
Electromagnetic fields propagate as waves and travel
at the speed of light (C). The wavelength is proportional
to the frequency.
λ(wavelength) = C (speed of light) / f (frequency)
If the distance to the field source is less than three
wavelengths, then we are usually in the near-field. If the
distance is more than three wavelengths, then far-field
conditions usually hold.
In near-field conditions, the magnetic field value cannot
be calculated from the electric field value. This meter is
designed for reliable far-field measurements only.
