摘要： An assembly includes a power supply and a meter. The power supply has a cable with a plurality of pins providing different voltages to a corresponding plurality of receiving pins. Each pin is connected to one of the receiving pins by a resistor of known value. The meter measures voltages of all of the resistors and all of the receiving pins simultaneously. Current passing through each of the resistors is calculated as a quotient of a voltage measured across each resistor and the known value of the resistor. Power delivered to each receiving pin is calculated as a product of the calculated current through the corresponding resistor and a voltage measured at the receiving pin with respect to ground. The total output power of the power supply is the sum of the powers calculated for each of the receiving pins.

摘要： A method of testing power-on reset circuitry in an integrated circuit comprises establishing the a first state of the integrated circuit that is different from a normal reset state of the circuit, lowering the VCC power supply voltage from a normal high operating level VH to a specified lower level VP then raising it back to the normal high level, then determining whether or not the integrated circuit has assumed the reset state. The testing can repeated with a plurality of lower VCC levels VP and under a variety of operating conditions to characterize resetting parameters and to designate pass/fail results for individual chips. If an AC voltage detector is part of the power-on reset circuitry, then it can tested separately, and DC testing occurs with very slow ramp rates for lowering and raising the power supply voltage.

The electricity meter includes a power consumption metering system for measuring the amount of power consumed from the service line, a peripheral device providing a non-critical function, a power converter, and a load management system. The metering system includes a controller and data storage for storing power consumption data. The power converter provides an unregulated voltage output at the terminals of a capacitor for powering the metering system. The load management system selectively couples and decouples the peripheral device from the power converter. The load management system senses the unregulated voltage to determine whether to couple or decouple the peripheral device. A load management system for an electricity meter and a method of managing the loads on the power system of an electricity meter are also disclosed.
