5.8 Graph Tab
The graph provides a 2-axis (X,Y) plot of the measured field strength. The graph can be
used to visually see hard and soft iron effects within the environment measured by the Prime
module as well as corrected output after a field calibration has been performed. (The screen
shot shown shows the MX and MY readings as the module was held horizontally and rotated
through 360º in the horizontal plane, then held in vertical orientation and rotated 360º in the
vertical plane.)
