General Description

The CAL01 reference magnet provides a stable and convenient method to verify the accuracy and

calibration of the USB 2510x series magnetometers. The CAL01 reference magnet is composed

of two axially magnetized permanent magnet rings that allow a probe to access the working region

of the fixture from both axial and transverse orientations, making the calibration fixture useful for

both axial and transverse probe calibration. Unlike conventional reference magnets that rely on

placing a probe in a fixed position, which produce an error if the magnet hole is improperly sized or

the probe is not shimmed correctly, the CAL01 is designed so that magnet can be moved with

respect to the probe in order to allow the user to find the positive and negative peak magnetic field

values, which are used to compute the calibration factors. When used in combination with

MultiDimension’s graphical data logging user interface, this technique minimizes errors from probe

misalignment and permits rapid accurate calibration of the USB2510x magnetometer probes. The

plots below show the peak field values when moving an axial probe through the axial hole and

when rotating the magnet around a transverse probe in the transverse hole.
