[QUOTE="keep_hope_alive, post: 8253948, member: 576029"] you will NEVER measure 0.0 ohms. there is resistance in everything - especially the connections. there is even resistance in the meter leads and between the meter tip and surface. most meters are horribly inaccurate at low resistance. to measure low resistances, you use a resistor in-line with the leads. the resistor should be sized to be in the meter's highest accuracy at a 0.01 ohms. some meters won't get that accurate and your best is a tenth.
