unstable due to loose ferromagnetic cores inside, i.e., the vertical misalignment changes when the sensor is turned ’upside down’ during the DI-measurement. We have found a way to glue the ferromagnetic cores within the new sensors
to make them mechanically stable. All sensors are tested very carefully before being used. Since the observed erroneous sensor offset due to loose sensor usually is extremely high, we can use a fast method (called ’double offset’) for a first
check of the sensor. However, the definitive test of a sensor is the comparison of its offset measured in a zero-field chamber with the offset calculated from an absolute measurement.
