5.The meter will continue to make real-time measurements until you initiate making the time- averaged measurement.

6.Determine where you want to make the averaged measurement and place or hold the probe in the desired position. For short intervals, it may be practical to hold the meter in one hand and the probe in the other. For longer intervals, it is suggested that you place the probe on some form of non-conductive stand so that it does not move. At frequencies above 50 MHz, the meter should be separated from the probe by a minimum of 12 inches (30 centimeters) to minimize any interaction between the meter, the probe, and the electromagnetic field. At the lower frequencies, the measurement techniques are very different. See Low Frequency Measurements in the Applications Booklet.

7.Press F1 (START) when you are ready to begin the time-averaged measurement.

8.The averaged value is displayed on the screen and will flash each time it is updated (one second intervals). The meter will automatically stop at the end of the selected averaging interval.

9.To end time averaging prior to the end of the averaging interval, press F4 (STOP).

10.At the end of the averaging interval, the meter will show the time-averaged value and the averaging interval on the second line of the display. The maximum value will be shown on the third line of the display. The bar graph will be indicating the instantaneous field strength in real time.
