CORNET Microsystems ED-15 Electrosmog meter is designed for quick measurement of High frequency
(RF) Electromagnet wave field strength and power density level for living environments. It is excellent device
for individual or company with Electromagnetic wave safety concerns. It has bandwidth of 100MHz to 3GHz
useful detection range, high sensitivity of -55dBm to 0dBm and very fast response time.
Applications:
- High frequency (RF) Electromagnetic wave field strength measurement
- Mobile phone base station antenna radiation power density measurement
- Wireless communication applications (AM/FM, TDMA, GSM, DECT, CDMA)
- RF power measurement for transmitters
- Wireless LAN (Wi-Fi), Bluetooth, Ultra-wide-band detection, installation
- Spy camera, wireless bug finder
- Cellular/Cordless phone radiation safety level
- Microwave oven leakage detection
- Personal living environment EMF safety
Usage guide:
(1) Put the 9V battery in the ED15, Handle the ED15 with right hand in vertical direction, and
push the power switch button.
(2) The RF sensor is located in the left hand side of the ED15; please do not cover the RF
sensor area with hand or other objects.
(3) Measured RF field strength/power density is shown on the digital LCD display (with dBm
and uw/m2, mw/m²). 1st Push button can be used to select one of the two display mode.
(4) 8 LED lights. With Red, Yellow, and Green color on the right hand side of LCD window is
used for quick RF signal level indications.3 Red LEDs are used to indicate the 3 safety
range. The power level of each LED can be found in the table on the ED15 front panel.
(5) Histogram of previous 30 signal level readings are recorded and shown as moving graph
on the LCD display
(6) Bar segment display can be used for relative signal strength indication.
(7) Most high frequency RF antenna such as Mobile phone base station is vertical polarized
(in vertical direction), therefore the ED15 is normally used in vertical direction. Please
rotate the ED15 to find the maximum power reading direction to take care of RF wave
reflections. The ED15 can also be used to find the location of signal source.
(8) Most of modern communication devices (Mobile phone, Wireless LAN, Wi-Fi, etc.,) use
digital communication technology with burst RF signals. When measuring this type of
RF signals, several LED lights will blinking at the same time. This is normal and can be
used as an indication of burst type of RF signals. For continues waves (AM/FM)
signals, the LED light will stable. ED15 measures peak power density of signal with very
fast response time. It is more accurate than the needle style of readout which only
shown the average value of signal power most of the time.
(9) ED15 is a broadband High frequency (RF) type of Electrical field measuring device. It is
used for applications such as Mobile phone base station antenna radiation, Microwave
oven, Cellular/cordless phone, Radio transmitters, and WiFi wireless LAN installation
aid. It is not for low frequency magnetic field measurement (AC power Line, transformer,
high voltage power transmission line, motor ...) which should be measured with Gauss-meters
devices. Such as CORNET model ED25G RF/LF dual mode meters.
10) To get into the Hold mode, toggle the 2nd button under the power switch, the “Hold” sign will
show on the LCD display when in Hold mode.
11) To turn on/off the LCD back light,
the 1st push button to toggle the LCD back light on and off.
when it is not required to save the battery power consumptions.
use 2nd push button to get into the “HOLD” mode first, then use
Remember to turn off the LCD backlight
Field strength/power density readout:
ED15 use 8 high brightness LED to indicate the measured power density with 3

NOTE:
* Electromagnetic wave field strength/power density decades very fast with distance (distance
square), keep a good distance from the high frequency RF signal source can reduce the high
frequency radiation effect. Alumina foil or window sun reflector film (silver color) can be
used as a effective and low cost shielding material for most of RF radiations.
* ED15 is designed for quick living environment RF radiation evaluation and is for reference use
only. Official RF safety radiation measurement procedure is complicate and should be
handled by trained technical person with lab instruments. Safety range standard listed here is for
reference only. ED15 is not a medical instrument, Please do not use it in medical, legal or other
related applications.
