Abstract:
1. A circuit arrangement for use in a utility meter; a processing circuit having a first mode and a second mode, and a least a first input and a second input, the processing circuit configured to perform a first set of metering operations related to energy metering in the first mode, and a second set of operations in the second mode, the second set of operations having fewer operations than the first set of operations, the processing circuit consuming less power in the second mode than in the first mode; a magnetically-actuated switch having a first state and a second state, the switch operably coupled to provide a first output signal to the second input of the processing circuit; a first circuit operably coupled to the magnetically-actuated switch, the first circuit configured generate a pulse signal responsive to the magnetically-actuated switch transitioning from the first state to the second state, the first circuit further operably coupled to provide the pulse signal to the first input of the processing circuit; wherein the processing circuit is configured to cause display of stored values responsive to receiving the pulse signal at the first input in the second mode and receiving the first output signal at the second input.
