    Chapter 10 Appendix 10.1 Effects of Extending the Measurement Lead and Induced Voltage The test lead extension is normally performed by Hioki. If you want extension performed, contact Regal Electro. Users should not extend the measurement leads. Reducing Induced Voltage Since the instrument measures a minute resistance with AC power, it is affected by induced voltage.

  • Page 84: Ac Four-Terminal Method

    10.3 AC Four-Terminal Method The instrument uses the AC four-terminal method, so that resistance measurement can be carried out with the resistance of the leads and the contact resistance between the leads and the object to be measured cancelled out. The following figure shows the principle of the AC four-terminal measurement method.
  • Page 85 Use of Hioki’s 9453 four-terminal lead or a similar lead to detect voltage on the inner side of the sources of current is desirable to avoid these effects. In other words, if measurement is conducted within the width (W) or thickness (t) of the subject of measurement, current distribution is likely to be stable.

  • Page 86: Synchronous Detection System

    Since when judging battery wear it is important to ascertain changes arising from the passage of time, use the same measurement lead for each measurement. 10.5 Synchronous Detection System The figure below shows an equivalent circuit for a battery. If the measured object exhibits other electrical characteristics in addition to resistance, as shown in the below image, we can use the synchronous detection system to obtain the effective resistance of the object.
