NOTE:
 Most high frequency RF antenna such as Mobile phone base station is vertical polarized
(in vertical direction), therefore while in RF mode, the ED88 is normally used in vertical
direction. For LF mode, the LF sensor is located in the top right hand of the ED88 and the
meter is normally used in Horizontal position in LF mode. For E-field mode, the E-field sensor
is located in the top middle of the meter, point the sensor to the ELF source. Please rotate the
meter to find the maximum reading direction in either case. The maximum reading will also
increase as you approach the source. ED88 can be used to find the location of signal source.
 Most of modern communication devices (Mobile phone, Wireless LAN, Wi-Fi, etc.,) use
digital RF burst signals. When measuring this type of signals, several LED lights will blinking
at the same time. this is normal and it can be used as an indication of burst type of RF signals.
For continues waves (AM/FM) signals, the LED light will be stable. ED88 measures the peak
power density of the signal with very fast sampling time. It is more accurate than the needle style
of readout which only shown the average value of signal power most of the time.
 Electromagnetic wave field strength/power density reduces 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 an effective and low cost shielding material for most of RF radiations.
 ED88 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 below is for
reference only. ED88 is not a medical instrument, Please do not use it in medical, legal or other
related applications.
 The “SENSOR” mark on the bottom of the back enclosure cover is not used in ED88
 ED88 is designed for home and personal use only, It is not for commercial rental purpose.
 The audio sound output of the sound function is the demodulated RF signal, it is good for AM
and modern digital RF signals (pulse/burst ) detection, it is not for FM or constant amplitude RF
signals or LF/ELF modes. it is an excellent tool for RF signal type indication. (different RF
signal such as Wifi, GSM, DECT, ….etc., all has different sound frequency signature of the
demodulated RF signal) and for very low level signal detection.
 When in E-field mode, the electric field induced by human body or large objects nearby can
affect the measurement results, hold the ED88 by hand on the lower right side of the meter, do
not cover the E-field sensor area (top of the meter) by hand or other objects, keep away from
large metal door or objects. Point the top of the ED88 to the high voltage AC power line (with
ED88 at least 1 meter above the ground) when measuring the VLF/ELF E-field radiation from AC
power lines or towers.
