    摘要： A current measurement apparatus for measurement value acquisition includes: a current sensor; and a current measurement transducer. A measurement range of the current sensor is adjustable. The current sensor includes at least one magnetic field sensor having at least one matching circuit and a memory. The current measurement transducer includes an input interface for inputting and/or a communication interface for transmitting information with respect to measurement range switching. The current measurement transducer includes an output interface for outputting the measurement values. The measurement range switching for the current sensor is based on the matching circuit accessing at least one new matching value in the memory, by which a change of the measurement signal of the magnetic field sensor is adjustable.

    摘要： The present application relates to a clamp meter and a clamp probe that can be matched for use with the clamp meter. The clamp meter comprises a main meter body having an interfacing connector and one or more clamp probes, wherein each of the clamp probes is detachably connectable to the interfacing connector of the main meter body. Each of the clamp probes has a converting unit that converts a signal measured by the clamp probe to an output measurement signal within a predetermined measurement range of the main meter body, and each of the clamp probes has an identity indicator readable by the main meter body. As the clamp meter according to the present application can be matched with a plurality of clamp probes having different measurement ranges, a user only needs to purchase one main meter body and one or more clamp probes of different models to meet various measuring needs. This can enhance the flexibility and extendibility of the usage of a clamp meter, as well as reduce the user's financial burden.

    摘要： A current detection module capable of differentiating and quantifying contribution to a current signal generated by a sensor in response to stimulation by a certain target source from contributions from sources other than the target source (ambient sources) is disclosed. As long as the contribution from the target source comprises a pulsed signal, the module may synchronize itself to the pulse(s) so that there is a predetermined phase relationship between the pulse(s) and functions carried out by various stages of the module. The module may be re-used to also detect and quantify contributions from ambient sources by presenting these contributions to the module as pulses that trigger synchronization of the module. To that end, a detection system disclosed herein is based on the use of such current detection module and allows mode switching where, depending on the selected mode of operation, the module is configured to perform different measurements.

    摘要翻译： 本发明涉及一种夹钳和夹钳，可与夹钳一起使用。 夹具计量器包括具有接口连接器和一个或多个夹具探针的主计量表主体，其中每个夹具探针可拆卸地连接到主计量器主体的接口连接器。 每个夹具探针具有转换单元，其将由夹具探针测量的信号转换成主仪表主体的预定测量范围内的输出测量信号，并且每个夹具探针具有可由主仪表主体读取的身份指示器 。 由于根据本申请的夹钳可以与具有不同测量范围的多个夹具探头匹配，所以用户仅需要购买一个主仪表体和一个或多个不同型号的夹具探针，以满足各种测量需要。 这可以增强钳表使用的灵活性和可扩展性，并减少用户的财务负担。
