CORNET ED-88TPlus Electrosmog meter user's manual
CORNET Microsystem Inc., ED-88Plus Electrosmog meter is a Tri-mode device for quick measurement of
both High frequency RF Electromagnetic wave field s ( )
Magnetic field level( Gauss Tesla , and Low frequency ( , )
an excellent device for individual or company with Electromagnetic wave safety concerns. It has RF
bandwidth of 100 MHz to GHz w 8 ith high sensitivity (0.5
50 Hz to KHz) with sensitivity of 0.1uT to 60uT(1mG-600 1
bandwidth of 50 Hz -50KHz with sensitivity of 10 / v m to
2.7 GHz can detect very short burst of digital RF down to )
Applications:
- High frequency RF Electromagnetic wave field strength, power density and frequency measurement
- Low frequency LF Magnetic field measurement ( Gauss meter function
- Low frequency ELF Electric field measurement E ( -field meter function)
- Mobile phone base station antenna radiation power density measurement

- Spy camera wireless bug finder , , IOT devices
- Cellular Cordless phone ra / diation safety level Electrical Utilities SMART ,
- AC power line High voltage tower power Transformer motors and small appliance EMF , ,
- Microwave oven leakage detection
- Personal living environment EMF safety evaluation
Usage guide:
(1) Put the V battery in the 9 ED88Plus, Handle the unit with right hand in vertical direction and
volume power switch / to turn on the power it will come up with RF ,
(2) The RF sensor is located in the left hand side of the ED88PLus; the LF sensor is located in the right
hand top side of the ED88Plus, the E-field sensor is located in the middle top side of the ED88Plus,
please do not cover the sensor area with hand or other objects.
(3) There are 4 push button on the ED 88 Plus : "Mode", "Hold", "LIGHT", and "UNIT" button, "MODE"
button is used to switch in between RF mode, two LF modes, and E-field mode. The "Hold" button is
used to freeze the data reading of the ED88Plus.
(4) RF mode: measured RF field strength power density is shown on the digital LCD display /
with dBm v m or mw m 2
( , / , / ). 8 LED lights with Red Yellow and Green color on the right hand
side of LCD window are used for quick RF signal level indications. 3 Red LEDs are used to
indicate the 3 safety ranges. The power level of each LED can be found in the table on the
ED88Plus back panel. Frequency of signal detected is displayed on the LCD display.
(5) LF mode: measured LF magnetic field strength is shown on the digital LCD display with uT
and mGauss). Two LF modes can be selected by "Mode" button: ( ) a LF30mode (0.1mG-10
and b ( )LF 600 mode (1mG-600 mG ). 8 color LED lights are also available to show the relative
strength of the magnetic field.
(6) E-field mode: measured ELF electric field strength is shown on the digital LCD display with V m
(7) Histogram: previous 30 signal level readings are recorded and shown as moving graph
on the LCD display for RF, LF, and E-field modes. It can be used for finding direction of signal source
and recording bursts from digital RF signals such as signals from AC smart meter.
(8) Hold &UNIT: HOLD button can be used to halt the data measurement of the ED88Plus, a "HOLD"
Mark will shown on the LCD screen to indicate the "Hold" condition. Push the "HOLD" button again the
ED88Plus will exit from the "Hold" condition. "UNIT" button can select the mw m v m or dBm unit
(9) MAX: Maximum measured data value since the last power-on is shown on the LCD display.
(10) Average: average or peak average value is displayed on the LCD with "A" or "P" mark It can be
used to estimate the duty cycle of the digital RF burst signals or the average of peak signal level.
(11) Sound function & LCD backlight: go into the "Hold mode" first, then toggle the "UNIT" button
in sequence to turn-on/off the Sound signature function, a "S" mark on the LCD indicates the sound
mode is on). Wheel Volume control can adjust the sound level.

The "LIGHT" button can be used to turn on off the LCD back light /
back light or the sound when it is not needed to reduce the battery current consumption.
