                                Many ohmmeters look like the following diagram.

                                Second Method: Get an ESR Meter (Equivalent Series Resistance) ($100-$300), these are essentially AC Ohmmeters with fixed or variable frequency.

                                Clearly, detecting the opening and closing of the points under static conditions will be somewhat problematic since most ohmmeters will not just be able to detect such a small change in resistance.

                                Simple ohmmeters cannot measure low resistances accurately because the resistance of their measuring leads causes a voltage drop that interferes with the measurement, so more accurate devices use four-terminal sensing.

                                Most technicians know that the red lead of some ohmmeters is negative while on other ohmmeters it is positive, thus it is important to establish the correct polarity versus color prior to checking diodes or other devices.
