A good MM will have an adjust screw center of unit below pivot of needle. That's on a galvanic response meter. If it's digital, there should be a zero button which you press while holding the leads together. Touch leads together and adjust to ZERO if yours has the adjustment screw, or press the zero button. Also, low batteries will cause a bad reading. OTTouch MM leads together before test to get a true 0 reading.
Might be .2-.3 ohms due to lead resistance.
