Peter,
The main purpose of the OHM function is to read resistance between two points...for the average handyman, this function is used mainly to find continuity, or a good path between any two points.
On any scale, sticking the probes together will deflect the needle and tell you 'things are touching'. It's the same deal when you check your light switch. Stick one probe on a terminal, and with the other probe you will be able to see which terminals are connected electrically to the first.
It lets you see what is hooked to what when the switch is open, closed, on 'park' etc.
Select the function that might read RX10, or some such thing. You will know it because when both probes are touched together, the needle will deflect.
Basically, this function shows a path between one probe and the other probe. Technically it will do more than just show continuity.
Sorry for stealing the spotlight Carl...it's the mad scientist in me!
