8.3 SPATIAL AVERAGE
The SPATIAL AVERAGE operating mode enables the spatial averaging of measured
field strength values over 1 to a maximum of 100 measuring positions. It can also be use-
ful to measure at a single measuring position, in order to record the field strength in a
specific spatial volume there, averaged over the desired measuring time, by continuous
movement of the measuring probe.
The spatial averaging is determined by quadratic averaging over all measured positions
and displayed as a horizontal line in the bar graph. The measurement per position can be
stopped automatically after a preset time or manually. An adjustable delay allows the per-
son performing the measurement to leave the measurement site before the measure-
ment starts.
