Optoelectronic measuring device having magnetic compass and compensation functionality

A method for determining an azimuthal alignment of an optoelectronic measuring device, wherein the measuring device has a magnetic compass and is adapted to assume a plurality of defined, repeatable operating states each having a different device-fixed interference field, wherein the method comprises:

• initially compensating the electronic magnetic compass in a first operating state of the measuring device, and
• determining the azimuthal alignment of the measuring device by means of the magnetic compass in a second operating state of the measuring device, further comprising:
• automatically recognizing the first operating state and the second operating state, and
• automatically provisioning items of information about a magnetic offset resulting from the different device-fixed interference fields between the first and the second operating state,
• wherein the determination of the azimuthal alignment takes place in consideration of the magnetic offset.
