for default operation. When AUTO is selected the application (e.g.,
Channel Power or OTA) controls the axes and switches as needed.
With the AUTO setting, all antenna elements (X, Y, and Z) are OFF.
This softkey is only active when Antenna Select is set to Tri Axial.

With Sum All, the field strength from all three axes is summed and
displayed. The RF measurements are switched between the three
different antennas (three dipoles), and the resulting summation of
the total power collected, and averaged.
Alternatively, you can select either of three axes to individually
measure the field strength in the one direction.
c. Else, to manually set one of the triaxial antenna's three axes to
individually measure the field strength in one direction.
i. Press EMF Off
ii. Select a single
uncorrected use. [X, Y, or Z] is displayed to indicate which
one of the X/Y/Z dipole axes is enabled. If for example the
X axis has been selected in the System > Utilities > EMF
Antennas menu, then Antenna Axis [X] is displayed to
indicate the X axis measurement (i.e., this uncorrected
manual mode is typically used when no EMF Option 358 is
installed). Refer to
For corrected manual single axis EMF measurements, refer to
