发明名称 MEASURING APPARATUS
摘要 A measuring apparatus includes a measuring unit for measuring an electrical characteristic of a measurement object by applying an electrical signal, and a discharge detection unit connected to the measuring unit, the discharge detection unit obtaining an electrical signal value that is the value of the electrical signal applied to the measurement object, wherein if the electrical signal value is smaller than a predetermined reference value, the discharge detection unit issues a discharge alarm to the outside when a difference value between the electrical signal value and the reference value becomes larger than a predetermined first comparison value after the difference value becomes smaller than the first comparison value, and wherein the reference value is set equal to or larger than the maximum of the electrical signal value when no electric discharge occurs.

主权项 1. A measuring apparatus comprising: a measuring unit for measuring an electrical characteristic of a measurement object by applying an electrical signal; and a discharge detection unit connected to the measuring unit, the discharge detection unit obtaining an electrical signal value that is the value of the electrical signal applied to the measurement object, wherein if the electrical signal value is smaller than a predetermined reference value, the discharge detection unit issues a discharge alarm to the outside when a difference value between the electrical signal value and the reference value becomes larger than a predetermined first comparison value after the difference value becomes smaller than the first comparison value, wherein the reference value is set equal to or larger than the maximum of the electrical signal value when no electric discharge occurs, and wherein the measurement unit applies the electrical signal to the measurement object so that the electrical signal value is maximized when the measurement of the measurement object is ended.
