    Appendix Appx. 1 Measurement Parameters and Calculation Formula In general, the impedance Z is used to evaluate the characteristics of, for example, circuit components. This instrument measures the voltage vectors of the object being measured against measurement current vectors, and then determines the impedance Z and the phase difference θ from these values.

  • Page 132: Appx. 2 Four-Terminal Pair Method

    Four-terminal Pair Method Appx. 2 Four-terminal Pair Method This instrument uses the four-terminal pair method as the measurement method. In addition to the characteristics of the AC four-terminal method, which is unaffected by the contact resistance, this is a more accurate method that is unaffected by the magnetic field caused by the measuring current.
  • Page 133 Four-terminal Pair Method In the four-terminal pair method, the current flows backward (current returns) with the same magnitude as the measuring current in the shields of the SOURCE cables, and then cancels the magnetic field of the measuring current. This method suppresses the induced electromotive force induced at the SENSE terminals, and detects the voltage actually generated in the object being measured.

If the shields are not connected, the impedance cannot be measured.
  • Page 135 Cautions When Making Your Own Measurement Probe • For the shape and position of the measurement probe, give attention to the points in the Figure shown below. Eddy currents from adjacent metal bodies or exogenous inductive noise may cause errors and variations in the measurement value and worsen the repetitive accuracy.

    Measurement Value in the Four-terminal Measurement (Difference in Measurement Value Due to the Measurement Probe) Reduction method of inductive voltage This instrument is subject to the influence of the inductive voltage because of the measurement of a micro resistance using AC. This inductive voltage means the voltage that is generated by the magnetic induction of the measurement current flowing in the lead wire which may affect the signal system of the measurement.
  • Page 138 Influence of the Eddy Current Appx. 6 Influence of the Eddy Current Measurement close to the metal body causes an eddy current to flow due to the dynamic magnetic field that is generated by the measurement current of the instrument. This eddy current generates an inductive voltage with a phase opposite to the measurement current in the measurement probe.
