Description

Each of the plurality of magnetic exposure measuring devices according to the present invention has a communication function, and information held by each magnetic exposure measuring device can be communicated with each other. As a result, the apparatus can be made compact and lightweight, and is convenient to carry.

That is, in order to display the integrated magnetic flux density value, the average magnetic flux density value, and the magnetic flux density numerically, an output device such as a liquid crystal is required. An input device such as a keyboard is required to set the magnetic flux density integration threshold, the average magnetic flux density threshold, and the magnetic flux density threshold. Such an output device or input device cannot be confirmed or operated without a certain size. The larger the housing, the heavier it becomes. In addition, since the power consumed by the output device and the input device is also necessary, in the case of battery operation, many shortcomings that arise in order to enhance the function, such as shortening the operation time, are due to the communication function provided in each magnetic exposure measuring device. It can be solved by exchanging information.
