ATT-8509 Electromagnetic field meter measuring procedure

Unit selection:
After inserting Probe card and connecting probe plug into Probe Input Socket, use Unit Button to select V/m, W/m^2, mW/cm^2.

Frequency team selection:
Use the Freq. Team Button to select the approx. measuring object frequency value.

If you don't know the exact information, the meter will select 1 GHz (EP-03H probe) or 1 MHz (EP-04L probe) on default after power on.

Axis measuring values:
Typically ATT-8509 presents the total value of XYZ directions, however if you would like to see values of X, Y, Z directions separately there should be the following steps taken:

  1. Power off ATT-8509, press Alarm Button and the Logger Button simultaneously, then power on the meter by press Power Button. After power on, release the buttons.
  2. *Press Unit Button continuously over 2 seconds, the bottom display will show X_axis, then release the button, the upper display will show X direction value.
    *Press Unit Button continuously and over 2 seconds, the bottom display will show V/m, then release the button, the upper display will show the total value of XYZ directions.

Data hold:
During the measurement, pressing of Hold Button once will hold the measured value and the LCD will indicate HOLD symbol. Pressing of it once again will release the data hold function.

Data Record (Max., Min. reading):

  1. The data record function records the maximum and minimum readings. Press REC Button once to start the Data Record function and you will see REC on the display.
  2. When there is REC on the display:
    - Press REC Button once, REC MAX symbol along with the maximum value will appear on the display.
    - Press REC Button once again, REC MIN symbol along will appear with the value accordingly.
  3. To exit the memory record function press REC Button and keep it pressed over 2 sec.
