- Reference magnets generate static magnetic fields of known magnitude with which the scale accuracy of the field intensity meter can be checked.
- Zero field chambers screen against external magnetic interference fields to a large extent.
With every switch-on the DEUTROMETER carries out an automatic zero adjustment. During this the probe must not be in any magnetic field. It is recommended to place the probe in the zero field chamber during switch-on. This way also the natural magnetic earth field is shielded to a large extent.
