Magnetic tampering detection and correction in a utility meter

An arrangement for use in an electricity meter, comprising:

• a sensor supported directly or indirectly by a meter housing, the sensor configured to measure a magnetic field in proximity to a current sensor of the electricity meter, the sensor configured to generate a measurement signal representative of, at least in part, a magnitude of the magnetic field;
• a processing circuit operably coupled to receive first information representative of the measurement signal and operably coupled to receive current measurement information representative of a current measurement signal generated by the current sensor based on the line current, the processing circuit configured to
• obtain a first value representative of the magnetic field based on the first information;
• determine a first adjustment value responsive to a determination that the first value exceeds a first threshold value;
• generate energy consumption information based at least in part on the first adjustment value and the current measurement information;
• and
• a memory storing information correlating magnetic values to adjustment values, and wherein the processing circuit is further configured to determine the first adjustment value using at least part of the stored information correlating magnetic values to adjustment values.
