  • Page 196: Appendix 2 Effect Of Thermal Emf

    Because this instrument functions by measuring potential difference while applying a constant direct RM3543 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 197: Appendix 3 Unstable Measurement Values.a

    Figs. 2 and 3. If thermal emf is a problem, use the RM3543’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- necting parts (test object or connectors).

  • Page 199 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. HIOKI RM3543A981-04...
  • Page 200 When measuring high-inductance (high-Q) DUTs such as large transformers or motors, measured values may be unstable. The RM3543 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.
