摘要： A battery tester capable of measuring resistance and voltage of a battery using the same input channel. When measuring battery resistance, a testing signal circuit is electrically coupled to two electrodes of a subject battery to conduct a testing signal used in the battery resistance measurement. A response sensing circuit of the battery tester is also electrically coupled to the two electrodes of the subject battery to measure a response signal across the two electrodes of the subject battery. A resistance measuring module is electrically coupled to the response sensing circuit to measure the battery resistance based on the response signal detected by the response sensing circuit. A circuit breaker is capable of disconnecting the subject battery from the testing signal circuit, and disconnecting the resistance measuring module from the response sensing circuit. Moreover, the battery tester can also provide automatic protection for the battery resistance measuring module.

摘要： A high resolution data acquisition (DAQ) system is initially calibrated with a reference source having a resolution higher than the DAQ system. Measurements over the operating range of the DAQ system are taken, and characteristic calibration coefficients are determined from the measurements. Software corrections based upon the calibration coefficients are made to DAQ system measurements. A digital to analog converter (DAC) on-board the DAQ system having a lower resolution than the DAQ system is calibrated by generating a look-up table of input digital codewords and output electrical signals measured by the calibrated DAQ system. This look-up table is used to field calibrate the DAQ system using only the DAC, rather than the high resolution reference source.

摘要： A power meter has a measuring circuit composed entirely of analog components that measures the instantaneous current draw of one or more electrical devices, such as home appliances. The power meter may be in the form of a hand-held device that includes elongated connections that allow a homeowner to measure the current draw of an electrical device without significant displacement of the electrical device. In addition to measuring current draw, the power meter may provide an estimated wattage consumed by the measured electrical devices.

摘要： A four-wire ohmmeter connector includes a pair of elongated members spaced apart from each other by an interconnecting web. A pair of elongated contacts are mounted on forwardly projecting portions of each of the elongated members. An insulative housing surrounds the elongated members, contacts and web. The contacts mounted on one of the elongated members are connected through separate wires to a positive probe, and the contacts mounted on the other of the elongated members are connected through separate wires to a negative probe. The elongated members are inserted into respective terminal apertures of a four-wire ohmmeter. A pair of semi-cylindrical conductive sleeves are aligned with each of the apertures, and they make contact with and compress the respective contacts that are inserted into the aperture.

摘要： An aircraft multi-function wire and low voltage insulation tester, having a time domain reflectometer, a digital multi-meter, and a matrix switch integrated in a computer, and a connector having a plurality of output pins allowing a plurality of wires to be hooked up simultaneously. The matrix switch connects the output pins to either the digital multi-meter or the time domain reflectometer perform the respective tests. Corresponding to the output pins, the matrix switch has a plurality of input/output channels, such that wire paths can be established between the output pins. The time domain reflectometry and characteristic tests can thus be performed on each line of a cable to be tested, and each wire path established between the output pins or the lines.

摘要： A hooking-type fully automatic electric meter with a function of fully automatic detecting and choosing a measuring mode among the electric current, voltage and resistance measuring modes. A user only needs to turn on the electric power of the electric meter without performing any other procedures; he can get an accurate reading of the volume of electricity on the display screen. The meter is different from the manually selected clamping type meters with different functional positions for measuring the values of electric current, voltage and resistance. With the meter, damage to the main body of the electric meter in operating electric measuring and to the safety of the user himself can be avoided. This can significantly raise the industrial safety in measuring large volume of electric current, and can save actions and time for operating the electric meter, and convenience and efficiency in operating can be increased.

摘要： An electronic instrument with a housing having a battery compartment. The housing has a probe connector oriented on a probe axis, so that a probe may be connected to the instrument via the connector for interfacing with a device under test. A removable battery cover encloses the battery compartment, and has a probe aperture registered with the probe connector, so that a probe may be connected when the battery cover is installed. To prevent removal of the battery cover when a probe is connected to the probe connector, the battery cover is constrained against movement along the probe axis. In addition, the battery cover may contain a conductive safety element necessary to complete a circuit between the battery and other components in the instrument, so that the batteries are capable of delivering power only when the cover is properly installed.
