COMMENTS: System continuously running. Ambient temperature 62°F and relative humidity of 55%. Test distance of 3 meters was due to the presents of ambient radio noise. Limits are extrapolated at 56.53 dB/decade derived by taking measurements at two distances at one radial (see 15.31 (f)(2)). Calculation of limit at 128kHz: Limit in microvolts/meter 2400/128=18.75μV/m at 300 meters Convert to dbμV 20 Log 18.75μV/m = 25.46dBμV/m at 300 meters Take the Log of the ratio of the distance between 300 and 10 Log 300/10 = 1.477 Multiply this distance ratio with the extrapolation factor 1.477*56.53dB/decade = 83.50 factor for 10 meter distance Add this factor to the limit of 25.46dBμV/m 25.46+83.50=108.96dBμV/m at 10 meters 0019PROMI_subc Page 15 of 16 Atlas Compliance & Engineering, Inc. 142 North Milpitas Blvd. PMB 376 Milpitas, CA 95035 Phone 831.761.2223 Fax 831.761.3223 Calculation of extrapolation factor at 128kHz, 3 meter to 10 meter distance: The reading level in dB at 10 meter subtracted from the level in dB at 3 meter 96.37-66.81 = 29.56 Subtract the log of the two distances Log (10)-Log (3) = 1-0.477121 = 0.522879 Divide the ratio of the readings by the ratio of the distance 29.56/0.522879 = 56.53 Actual Extrapolation Factor derived from measurements at 3 meters and 10 meters on fundamental frequency 56.53 dB/decade Levels at 3 and 10 meters were measured, levels at 30 and 300 meters are calculated.
