RadiMation Application Note 153

multi axis field probe corrections

Introduction

This application note provides an overview of the functionality associated with the correction files for the field sensor device driver. The correction files serve to correct measurements taken by the sensor. There are two types of correction files that can be added: multiplication (multiply) and offset. The type of correction file used in conjunction with the driver determines whether isotropic or axis-specific correction is applied to the sensor data.

Correction File Types

Axis-Specific Correction
To implement axis-specific corrections, the correction file must include columns labeled "X-axis correction," "Y-axis correction," and "Z-axis correction." These columns contain the correction values corresponding to the respective axes.

Isotropic Correction
For isotropic corrections, a single "correction" column can be added to the correction file. This column holds the correction values applicable to all axes.

Refer to the manual for further details.

Using multi axis field probe corrections

Probe Supports Multi-Axis Measurements and Axis-Specific Corrections: If the probe supports multi-axis measurements and axis-specific corrections are present in the correction file, the test will start successfully. The measured values will be corrected in an axis-specific manner.

Probe Supports Multi-Axis Measurements and Isotropic Corrections: When the probe supports multi-axis measurements and isotropic corrections are present, the test will start successfully. The measured values will be isotropically corrected for all axes.

Probe Doesn't Support Multi-Axis Measurements but Has Axis-Specific Corrections: If the probe doesn't support multi-axis measurements but axis-specific corrections are present, an error will be generated. The error message will indicate that the probe cannot perform measurements with the current correction files.

Probe Doesn't Support Multi-Axis Measurements and Has Isotropic Corrections: When the probe lacks multi-axis measurement support and has isotropic corrections, the test will start successfully. The measured values will be isotropically corrected.

== Conclusion== The functionality of correction files in the field sensor device driver allows for precise measurement of sensor measurements. By incorporating axis-specific and isotropic correction options, the driver ensures accurate and context-appropriate data corrections. It's essential to consider the compatibility of the probe's measurement capabilities and the correction file contents to achieve successful measurements. This versatility enhances the usability of the field sensor device across various use cases.
