How to Use a Tesla Meter?

[DelKyle]

Tesla meters are used to measure magnetic field strength. Here is relevant information: 1. Usage: The most important component of a Tesla meter is the Hall effect sensor probe, which senses the magnetic field. The probe is usually shielded within a probe cover. After opening the probe, you will find that this guide introduces a transverse probe (axial probes are not covered in this guide). The largest surface of the transverse probe should be perpendicular to the magnetic field. 2. Precautions: The transverse probe has two largest surfaces, so the measured values can be positive or negative. The narrower surface of the transverse probe is not for sensing the magnetic field and should not, in principle, detect any magnetic field.
