properly configured with respect to the mounting orientation, Endianness, north reference,

etc.

Section 6.5 outlines how to perform a calibration using TRAX Studio, while Section 7.6.2

provides a step-by-step example of how to perform a calibration using the PNI protocol.

5.1.1 Full-Range Calibration

A Full-Range Calibration is appropriate when the TRAX can be tilted ±45° or more. This

method compensates for hard and soft-iron effects in three dimensions, and allows for the

highest accuracy readings. The recommended 12 point calibration pattern is a series of 3

circles of evenly spaced points, as illustrated in Figure 5-1 and listed in Table 5-2. The

pitch used in the second and third circles of the calibration should at least match the

maximum and minimum pitch the device is expected to encounter in use.

Note: While Figure 5-1 shows the location of the device changing, this is for illustration purposes and

it is best for the location of the device to remain constant while only the orientation is changed.
