Usage guide:
(1) Put the V battery in the9ED88Plus,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 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 4push button on the ED Plus88 : “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 m28LED 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 safety3ranges.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: ( )aLF30mode (0.1mG-10 )mG
and b( )LF mode600 (1mG-600 ).mG 8color 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 signal level readings are recorded and shown as moving graph30
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/ 2, / , .
(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.Audio Sound can be used to detect
very low level RF signals down to uw m( 0.05 / 2)especially for the modern digital RF burst signals.
The “LIGHT” button can be used to turn on off the LCD back light/ . (Remember to turn-off the LCD
back light or the sound when it is not needed to reduce the battery current consumption.
(12) SysSetup Menu:can be enabled by push and hold the “HOLD” button then push the “UNIT” button
to get into the SysSetup menu U.se the “ ”>button to move the cursor in the Menu
and use the “ ”<button to enable disable the function/s In the SysSetup menu:
( )aEXIT:exit the SysSetup menu return to normal mode,
(b)RF level Unit select:select default mw m/2, / ,v m or dBm mode when meter is powered on.
( )cLED Level:used to adjust the color LED segment display level for custom safety standards
OFF,-5,-10,-15, or -20 . (dB use -20dB for “SBM2008 Building Biology Testing Methods” )
( )dAverage Frequency/ : select Peak average,All average or,Frequency 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 8trigger 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).
( )eRESET:reset to default ( /mw m2,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 LF mode30 : has high sensitivity (0.1mG-10 ),mG but with lower frequency range
(50Hz – 1 )KHz to reduce the high frequency noise. (The Histogram and LED
segment display can go up to mG30 )
The LF mode600 : with sensitivity (1mG-600 )mG ,has higher frequency coverage (50Hz -10 ).KHz
When measuring the high frequency digital pulse type of/signals,(such as switching power supply)
the LF mode might have lower reading than the LF mode this is due to the lower frequency30 600 ,
coverage range of the LF mode30 .
(14) While in LF (magnetic/electric field measurement)or E-field mode please hold the,ED88 steady to
get the good stable reading avoid fast moving of the,ED88 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 ED88, and wait a few minutes to capture the RF signals from smart meter.
Field strength power density readout/ :
ED88Plus use high brightness LED to indicate the measured po8wer density with safety3
