    Appendix 1 Four-Terminal (Voltage-Drop) Method Appendix Four-Terminal (Voltage-Drop) Appendix 1 Method The Four-Terminal method is essential for measuring very small resistance values. With two-terminal measurements (Fig. 1), the resistance of the test leads is included in the measured resis- tance, resulting in measurement errors. The four-terminal method (Fig.

  • Page 192: Appendix 2 Effect Of Thermal Emf

    Because this instrument functions by measuring potential difference while applying a constant direct RM3542 current through the test object, the effect of thermal emf can affect measurements. The amplitude of ther- mal emf depends on the temperature of the measure- ment environment, with the force generally being greater at higher temperature.
  • Page 193 Figs. 2 and 3. If thermal emf is a problem, use the RM3542’s OVC function. If OVC cannot be used for reasons such as tact time limitations, use a low-thermal emf material such as copper for wiring, and protect against airflow on con-...

  • Page 195 Varnished windings are more susceptible to temperature increase, so the resistance tends to be relatively high. Use an instrument with a temperature-compensation function such as the Hioki RM3544, RM3545, and RM3548 to minimize copper-like temperature dependence.
  • Page 196 When measuring high-inductance (high-Q) DUTs such as large transformers or motors, measured values may be unstable. The RM3542 depends on constant current flow through the DUT, but producing constant current becomes impossible as inductance approaches infinity. To obtain stability in a constant-current source with a large inductance, response time is sacrificed.
  • Page 197 Appendix 3 Unstable Measurement Values (10) Non-Four-Terminal Measurements H CUR The four-terminal method requires that four probes be connected to the H POT L POT DUT. L CUR By measuring as shown in Fig.10, the measured resistance includes that of the contacts between the probes and DUT. Typical contact resistance is several milliohm with gold plating, and several tens of milliohm with nickel plating.

    Although no delimiters are shown, they must be included at the end of each command line. Even when the reference standard resistance is set on the RM3542, the range is not automatically selected. Use the range setting command to set the same value as the reference standard resistance. When setting the same value as the reference standard using the range setting command, there are cases where the range is different from the RM3542’s auto-ranging selection, depending on the value.

For this reason, zero adjustment must be performed when connection is made to 0 . However, connecting a sample with no resistance is difficult and therefore is not practical.
