Annex D: Probe configuration / signal output
The internal sensor coils are arranged orthogonally. The configuration of the
coils is not immediately visible externally.
If you require the result display to be referred to the spatial axes of the room
in which the measurement is made, the probe coils must be configured so
that they match the spatial axes of the room.
Use the diagram below to position the probe correctly.
