2D Calibration

A 2D Calibration is intended for very low tilt operation (<5

°) where calibrating the TCM

with greater tilt is not practical.

This procedure calibrates for hard and soft iron effects in only two dimensions, and in

general is effective for operation and calibration in the tilt range of -5

° to +5°. The

recommended 12 point calibration pattern is a circle of evenly spaced points, as given in

Table 5-3.
