Abstract: A disk analog display for a solid state electricity meter includes a series of segments that illuminate sequentially to indicate the direction of current flowing through the meter and the rate at which energy is being consumed by the load. The sequential illumination provides notice to a technician that the meter is completing the measurement of one energy consumption unit so that the measurement by the meter of one energy consumption unit can be accurately timed. In one embodiment, there are three segments that illuminate sequentially to indicate that the meter is completing measurement of one energy consumption unit. The segments then simultaneously blank to indicate that the meter has completed the measurement of one energy consumption unit.

Abstract: A method and apparatus for calibrating tester timing accuracy during testing of integrated circuits. An ATE tester measures itself through reference blocks that have the same relevant dimensions as the integrated circuits to be tested. The number of reference blocks required is equal to the number of signal terminals on an integrated circuit to be tested being subject to timing calibration. A signal trace electrically connects a different signal terminal to a common reference terminal on each reference block. Each signal trace used should be closely matched both physically and electrically to the other signal traces used in the set of reference blocks, so that the electrical path length associated with each trace is nearly identical. To perform the timing calibration, the reference blocks may be mounted on a single fixture one at a time, or using multi-site fixtures, multiple reference blocks may be used in parallel. The fixture provides electrical connection of the reference block to the loadboard, and ultimately, the tester.

Abstract: A device for measuring power, or other circuit parameters, of an alternating current load. The device has an ammeter and voltmeter for measuring voltage across the load and current through the load. The device also has a known impedance element that is switchably connected across the load. The ammeter is used to provide a second current measurement with the impedance so connected. These measurements, together with the known impedance value, are used to calculate power, the power factor, impedance, or some other parameter associated with the load. The same device may also be implemented circuitry that is the “dual” of that described above, such that voltage rather than current measurements are used.
