User Manual

From operational mode,

measurement mode can be

initiated.

When “Start Measuring” is

clicked, make sure that the

MTw is kept still.

For best results, data should be

measured and recorded in the

same environment as when

measurement mode was

initiated.

Like all filters of its kind, the XKF‐3w filter is based on history. Therefore time is needed for

the XKF‐3w filters to settle to a stable state. This time is called settling time, see 3.3.2.

For about one minute after entering measurement mode, make calm, slow movements to

warm up the filters (the actual time depends on the amount of trackers in use, but one

minute should be sufficient).

To check if the filters have

been stabilised, ensure that

the orientation of the MTw

doesn’t change, when the

MTw is stationary (in a

magnetically undisturbed

environment).

When in measurement mode,

recording can be made.
