Looked at the MM's manual, says in continuity, when the resistance is <30 the indicator turns green, and <60 it turns red. Don't know what that means for + and -
When the two ends your putting the multimeter on, in continuity mode, are not connected, there is infinite resistance and it won't beep. If they are connected, there is little resistance, and it beeps.
Reading the last few posts got me wondering. I have a set of piston 3's that the cat has chewed the cable on and i'd like to re-terminate the wires onto a new jack. Is there a mode on a multi meter that will help me work out what wire is for what?
There's four wires in the main cable, super thin and some of them look like they have the earth wire wrapped around the outside of them.
As above. Continuity mode. If it beeps they are connected.
