A measuring device, a measuring method, and an evaluating device for easily and accurately obtaining information suitable to evaluate, for example, the discharge characteristic of an insulating film such as an MgO protective layer of a plasma display are provided. The device includes a third fluid mechanics cylinder, which moves the said piston of the dead space, wherein the third fluid mechanics cylinder is activated by means of a compressed fluid, supplied by means of an independent hydraulic system, in order to obtain continuous variation of the dead space. Each of the plurality of particles may propagate through the system model to generate a plurality of modeled particle values, each of which may be compared to a measurement of an electrical parameter of the battery system. The test executive sequence may be executed on a host computer under control of a test executive engine. Electrical signals corresponding to a coring speed may be provided to a controller that allows the coring head to be lowered to an operating position only if the signals are within the limited range of preset coring speed positions. The connection limitation allows a reduction in circuit scale.
