Usage guide:

(1) Put the 9V battery in the ED85EXPlus, Handle the unit with r ight hand in vertical direction, and turn on

the volume/power switch to turn on the power, it will come up with RF meter mode.

(2) The RF external SMA connector for external antenna is located on the top of ED85EXPlus; the LF

sensor is located in the right hand top side of the ED85EXP lus. please do not cover the sensor area with hand or ot her objects.

(3) There are 4 push button on the ED85EXPlus: “MODE”, “ HOLD”, ”LIGHT”, and “UNIT” button,

“MODE” button is used to switch in between RF mode, and two LF modes,. The “HOLD” button is

used to freeze the data reading of the ED85EXPlus. (4) R F mode: measured RF field strength/power density is shown on the digital LCD display (with dBm, v/m, or mw/m²). 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 standard of three country. The power level of each LED can be found in the table on the ED85EXPlus back cover. Frequency of input signal is displayed on LCD screen (for field strength measurement through build in internal antenna only, NOT for external SMA input signals) (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 “MO DE” button: (a) LF30mode (0.1mG-10mG)

and (b)LF600 mode (1mG-600mG). 8 color LED lights are also available to show the relative

strength of the magnetic field. (6) Hi stogram: previous 30 signal level readings are recorded and shown as moving graph on the LCD display for RF, and LF modes. It can be used for finding direction of signal source

and recording bursts from digital RF signals such as signa ls from AC smart meter. (7) HO LD &UNIT: HOLD button can be used to halt the data measurement of the ED85EXPlus, a “HOLD” Mark will show on the LCD screen to indicate the “Hold” condition. Push the “HOLD” button again the ED85EXPlus will exit from the “Hold” conditi on. “UNIT” button can select the mw/m2, v/m, or dBm unit. (8) M AX: Ma ximum measured data value since the last po wer-on is shown on the LCD display. (9) 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 pe ak signal level. (10) Sound function & LCD backlight: Toggling the “LIGHT” button can turn-on/off the LCD back light a nd the Audio Sound function, ( a “S” mark on the LCD indicates the sound mode i s on). Wheel Volume control can be used to adjust the sound level. Audio Sound can be used to detect very low level RF signals (down to 0.05uw/m2) especially for the digital RF burst signals. In order to reduce the battery current consumption please remember to turn-off the LCD back light or the sou nd when it is not needed. (11) Data Logging menu: Push and hold the “UNIT” button then click the “MODE” button to go into LoggerSetup menu. Please see the “ED85EXPlus Data Logging user Guide” from www.cornetmicro.com for details of the Data Logging functions.

(12) SysSetup Menu: Push and hold the “UNIT” button then push the “HOLD” button

to get into the SysSetup menu. Use the “>” button to move the cursor in the Menu and use the “<” button to enable/disable the functions In the SysSetup menu:

(a) EXIT: exit the SysSetup menu, return to normal mode (b) RF level Unit select: select default mw/m2, v/m, or dBm mode when meter is powered on. (c) LED Level: used to adjust the color LED segment display level for custom safety standards

OFF,-5,-10,-15,or -20dB. (use -20dB for “SBM2 008 Building Biology Testing Methods” ) (d) Average/P: select Peak average, or All average of MAX value display. (e) MAX_Clear bit: If the MAX_Clear is “ON” the MAX value can be cleared by toggling the “ HOLD” button. If it is “OFF” the MAX va lue can be cleared only by power-off the meter.

(f) Alarm: ON/OFF or one of the 8 trigger levels( 0, -5,-10,-15,-20,-25,-30,-35dBm) can be selected to trigge r the audio Alarm. *(Alarm function is used in RF mode only). (e) RESET: reset to defau lt (mw/m

,LED Level OFF, MAX_CLEAR ON, Alarm OFF,PeakAvg).

(g) SAVE: push the “<” button to save the chang es of setup to EEPROM memory. Do not

power off meter, Wait until save is done! (EXIT without SAVE to memory the changes will still functional, but it will lost if the meter is power-of f ).

(13) The LF30 mode: has hig h sensitivity (0.1mG-10mG), but with lower frequency ran ge

(50Hz – 1KHz) to reduce the high frequency noise. (The Histogram and LED segment display can go up to 30mG)

The LF600 mode: with sensitivity (1mG-600mG), has higher frequency coverage (50Hz -10KHz).

W hen measuring the high frequency digital/pulse type of signals,(such as switching power supply), the LF30 mode might have lower reading than th e LF600 mode, this

is due to the lower frequency coverage range of t he LF30 mode. (14) While in LF (magnetic/e lectric field measurement), please hold the ED85EXPlus steady to get the good stable reading, avoid fast moving of the ED85EXPlus to prevent the sudden change of the reading caused by the Earth magnetic fi eld or the induced electric field of nearby objects. (15) AC Smart Meter radiate s RF signal in short burst every few minutes, use MAX function and

Histogram function of ED85EXPlus, and wait a few minutes to capture the RF signals

from smart meter.

Field strength/power density readout:

ED85EXPlus use 8 high brightness LED to indicate the measured power density with 3 safety

Indications of three countries

ED85EXPlus V.1.0 05/29/2018

NOTE:

 Most high frequency RF antenna such as Mobile phon e base station is vertical polarized

(in vertical direction), therefore while in RF mode, the ED85 EXPlus is normally used in vertical direction. For LF mode, the LF sensor is located in the top right hand of the ED85EXPlus and the meter is normally used in Horizontal position i n LF mode. Please rotate the meter to find the maximum reading direction in either case. The maximum reading will also increase as you approach the source. ED85EXPlus can be used to find the location of signal source. ED85EXPlus measures the peak power densit y of the signal with very fast sampling time. of readout which only shown the average value of signal p ower most of the time.

 Electromagnetic wave field strength/power densit y reduces very fast with distance (distance

square), keep a good distance from the high freque ncy 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.

 ED85EXPlus 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 l ab instruments. Safety range standard listed below is for reference only. ED85EXPlus is not a m edical instrument, Please do not use it in medical, legal, commercial rental purpose or ot her related applications. (for personal use only)

 Turn the volume control to minimum first before plug in the earphone to the ED85EXPlus to

avoid damage to your ear by accident from high level sound produced by digital RF signals.

 The audio sound output of the sound function is the d emodulated RF signal, it is good for AM

and modern digital RF signals (pulse/burst ) detecti on, it is not for FM or constant amplitude RF signals or LF/ELF modes. It is an excellent tool for R F signal type indication. (different RF signal such as Wifi, GSM, DECT,

…………

.etc., all has different sound frequency signat ure of the

demodulated RF signal) and for very low level signal dete ction.

 The Maximum input power to the RF input SMA conne ctor is 10dBm (10mW), it might damage

the RF sensor of the ED85EXPlus if the RF input power level is over the limit. Use the 20dB attenuator in front of the RF input SMA connector before connecting the ED85EXPlus to any RF transmitter output. (Typical Max. RF output level of Wi Fi router is 100mW, CB radio is 2W ).
