will move from the left side to the far
right side. This shows that there are no breaks on the circuit.
●
If you Ohm a circuit and get no movement of
the needle or you get O.L. on a
digital meter, that means you have an open.
An open means that you have no continuity or a break in the circuit
somewhere, you've found a problem.
●
Unless your testing resistance of a diode, it
doesn't matter which lead
(red or black), is on a particular side of the
circuit.
●
Before you start any resistance check, always touch
together the two leads
on the meter and make sure you get somewhere
around zero Ohms. Note: most digital meters will produce around 0.1 to 0.3
Ohms when you do this.
●
Another thing to do before Ohming a circuit
is to always make sure to disconnect
power from that circuit before taking
any reading. If you don't, it can send current into the meter and destroy a
perfectly good meter.
