Transverse Probe Calibration Procedure

1. Press the “calibrate to field” button.

2. Set the calibration field value to the magnetic field value indicated on the side of the calibration

assembly

3. Make sure both sensitivity and offset checkboxes are selected

4. Insert transverse probe all the way into the transverse probe alignment hole.

5. Reset the chart in the calibration window

6.

Rotate the magnet in order to sample the largest positive voltage and the largest negative

voltage.

The probe can be wiggled and the magnet rotated back and forth around the field

extrema angles in order to sample the maximum and minimum values.

7. Save the calibration in either the flash for future use or just write the calibration to the sensor for

immediate use only

8. Exit the calibration window

9. Enter the digitizer window and turn on the low pass filter (LPF) if desired.

10. If the offset has not been adequately corrected, then perform one of the offset calibration

procedures
