I am trying to measure the resistance of the coils in a motor with an ohm meter. I was told that some of the new meters measure resistance by means of a time constant calculation while older meters send a current and measure the voltage drop using the equation V=IR. I was told by my professor to make sure that I use an older meter that does not use the time constant calculation as the inductance of the coils will throw off the reading.

How can I tell which way the multi-meter measures resistance?

Thank You!
