PROBLEM TO BE SOLVED: To provide a measuring system capable of measuring a resistance value, etc., without performing calibration for each terminal device.SOLUTION: A measuring system includes an input signal generation part 10 for generating an input signal of a predetermined frequency, a filter part 20 for generating a filtered signal in which power of the frequency of the input signal is attenuated according to one of the values of impedance, electrostatic capacity, and inductance, and a measurement value generation part 50 for generating a measurement value corresponding to one of the values of the impedance, the electrostatic capacity, and the inductance from the filtered signal. The input signal generation part 10 and the measurement value generation part 50 are composed of one terminal device, and the filter part 20 is provided outside the terminal device.SELECTED DRAWING: Figure 1【課題】端末装置ごとのキャリブレーションを行わなくても抵抗値等の測定が可能な測定システムを提供する。【解決手段】所定の周波数の入力信号を生成する入力信号生成部１０と、インピーダンス、静電容量、及びインダクタンスの何れかの値に応じて入力信号の周波数のパワーを減衰させた濾波信号を生成するフィルタ部２０と、濾波信号から、インピーダンス、静電容量、及びインダクタンスの何れかの値に対応させた測定値を生成する測定値生成部５０とを備え、入力信号生成部１０と測定値生成部５０は１つの端末装置で構成され、フィルタ部２０は端末装置の外部に設けられる。【選択図】図１
