Precision and Repeatability
The flux density is a vector. To measure the exact value of that vector, the
probe has to be highly perpendicular to the direction of the flux density.
For example to measure a flux density of 1 T accurate to 1 mT, the angle
deviation may not be lager than 2.56 °.
To further illustration: At a rotation with a radius of 100 mm this is only a
distance of 4.47 mm.
The repeatability extremely depends on the quality of the mechanically
fixation of the probe.

Winding up of Cables
Cables always should be wound up in a way that no knots or twists occur. To
ease you the winding up of the cable we have collected and mentioned
below some instructions available on the Internet.
