Regarding using an ohm meter: you want to use the smallest setting that is above the resistance that you're reading. So for example, to read 3 ohms, if your meter has a 2 ohm, 200 ohm, 2k ohm, and 20k ohm settings, select the 200 ohm setting. If you reading 1 ohm, select the 2 ohm setting, 1.5k ohm, select the 2k ohm setting, etc.

Also, when taking the measurement, if there is no reading displayed (such as in the case of an out of range indication), select the next highest meter setting -- until you have a reading.

Another approach, if you're measuring resistance but don't know how much resistance to expect is to start at the high end of the meter settings and work back down until you reach the best resolution possible with the meter.
