A magnetometer requiring calibration can be subjected automatically to a sequence of known applied fields, while the output is recorded on a computer.
Subsequent processing provides appropriate calibration parameters.
Manual operation is also available. The charge made for this service is dependent on the length of time and the complexity of the calibration required. A calibration certificate and a set of calibration curves appropriate for the particular magnetometer are provided. Benoit St-Louis . The Laboratory provides a calibration service for professional grade and military grade compasses.
