The last number in the score, Mn.n, describes the magnitude of local field. Larger numbers
denote strong local fields. Small local fields are preferable, since less correction will be
necessary, and they utilize less of the magnetometers’ dynamic range. A magnitude score
greater than 30 indicates strong magnetic fields at the TCM2.5/2.6 location; you should
consider alternative mounting locations. Any score less than 10 is very good.
Note: The calibration score values mostly provide a qualitative estimation. For
example, a good score would be H9V9Mn.n. A poor score as anything less than
H9V9Mn.n. A poor V score generally indicates that you need to tilt more during the
calibration. A poor H score indicates you did not turn two full circles or that you
turned too quickly.
6. If the calibration is not sufficient then click on the button and begin the calibration
again.
Clear:
This button will clear the user calibration in the unit. Once selected, the unit will revert back to
