Axial 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.

Push the axial probe into the axial alignment hole to find the maximum positive (negative)

voltage reading, you can wiggle the probe some and move in and out of the calibration

assembly to verify the maximum value has been sampled.

5.

Hold the probe steady and pull the calibration assembly away.

6.

Flip the calibration magnet in order to reverse the magnetic field

7.

Push the axial probe into the axial alignment hole to find the maximum negative (positive)

voltage reading, you can wiggle the probe some and move in and out of the calibration

assembly to verify the maximum value has been sampled.

8.

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

for immediate use only

9.

Exit the calibration window

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

11. If the offset has not been adequately corrected, perform one of the offset calibration procedures
