PROBLEM TO BE SOLVED: To provide a measuring instrument capable of executing speedy measurement and capable of obtaining an impedance locus from impedance measuring data. SOLUTION: An organism impedance measuring instrument consists of a measuring instrument main body 2, which is provided with a constant current output part 6, a current waveform measuring part 7, a voltage waveform measuring part 8 and a control part 21, and an electrode sensor part 1. Then, a constant current reference pulse is repeatedly injected plural times by alternating a plus side and a minus side to respectively add-average to the plus side and the minus side to reduce noise and to collect data in a memory at the same time of injecting the pulse to finish a series of measuring processing at the speed of a clock by hardware. A part 1 incorporates the parts 6, 7 and 8. In addition, it is possible to add an offset voltage removing function and/or a function cancelling the influence of commercial frequency noise. |
