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.
Fig. D-1 Probe configuration
Positioning the probe
⇒ Tilt the ELT-400 up by exactly 35.3° from the horizontal and secure it in
this position.
Top view: The effective coil cross sectional areas for the X and Z coils
are perpendicular. They are each oriented at 45° to the center axis.
Side view: The Y axis is perpendicular with the coil cross sectional area
horizontal.
