read the manual again slowly.
that is how we all learnt, rome was not built built in a day

what do u want to test continuity? dont test mains supply with it as u clearly are a novice . ELECTRICITY KILLS.
Hi again leepy.
This depends on what sort of meter you have got. Almost certainly yours can not measure low enough resistance to properly test circuits, but never mind.
Put it on the most sensitive resistance range it has got.
Touch the probes together firmly and adjust the zero-adjusting-knob so that the meter reads 0 ohms.
connect one probe to each end of the cable you want to check for continuity.
The meter should move from a very high reading when probes just in air, to a very low one when connected to the cable. Make sure you have a good contact either end. You expect a reading around 0-1 ohm.
Most off the shelf meters do not read this low accurately enough, but it will tell you if you have a connection of some sort.
make sure the probes are plugged into the correct sockets on the meter. There may be three or more for different measurements.
If your meter is accurate enough to tell, you should get the same reading between the two ends of the red cables as between the two ends of the black cables. The earth should give a reading about 1/3 more because the wire is thinner. The longer the wire, the higher the reading.
Practice twiddling all the knobs. Do not connect the meter directly across a voltage when it is set to measure amps. Something will go bang.

Leepy - please understand that this is not meant in any way to be patronising, but do you understand the difference between volts, amps and ohms?leepy said:cant quite follow it breezer can u explain in real terms how to test and reading i should get thankyou
Shouldn't even need a manual, then, at least for the voltage, current and resistance ranges...

just come back from flight in helicopter (am learning to fly one) read this post i have to agree with ban-all-sheds
reason i mentioned helicopter is i only said that doesn't mean its true though does it.

ban-all-sheds said:
"Volts" means jumps, over one of those horse things in gymnastics. Or you can do "Pole-volting", which sometimes involves a double-pole (switch)
"Amps" are what you stick in the boot of your car to drive your "subs". It is also an abbreviation of a small rodent pet, in East London. "I've just got a new Amps (ter)."
"Ohms" is what buddhists chant.
