Usage guide:
(1) Put the 9V battery in the ED85EXPlus, Handle the unit with right 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 ED85EXPlus.
please do not cover the sensor area with hand or other 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) RF 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 "MODE" 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) Histogram: 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 signals from AC smart meter.
(7) HOLD &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" condition. "UNIT" button can select the mw/m2, v/m, or
dBm unit.
(8) MAX: Maximum measured data value since the last power-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 peak signal level.
(10) Sound function & LCD backlight: Toggling the "LIGHT" button can turn-on/off the LCD back light and
the Audio Sound function, ( a "S" mark on the LCD indicates the sound mode is on). Wheel Volume
control can be used to adjust the sound level.
2
signals (down to 0.05uw/m ) 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 sound 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.

Audio Sound can be used to detect very low level RF
(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/m
(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
(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 value 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 trigger the audio Alarm. *(Alarm function is used in RF mode only).
2
(e) RESET: reset to default (mw/m ,LED Level OFF, MAX_CLEAR ON, Alarm OFF,PeakAvg).
(g) SAVE: push the "<" button to save the changes 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-off ).
(13) The LF30 mode: has high sensitivity (0.1mG-10mG), but with lower frequency range
(50Hz – 1KHz) to reduce the high frequency noise.
segment display can go up to 30mG)
The LF600 mode: with sensitivity (1mG-600mG), has higher frequency coverage (50Hz -10KHz).
When measuring the high frequency digital/pulse type of signals,(such as switching
power supply), the LF30 mode might have lower reading than the LF600 mode, this
is due to the lower frequency coverage range of the LF30 mode.
(14) While in LF (magnetic/electric 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 field or the induced electric field
of nearby objects.
(15) AC Smart Meter radiates 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 *Action is reference to ICNIRP (for reference only).
