Hi all can I check my RPM on a multimeter??

I'm sure you can but need to know how please??

Have a good pro multi meter....need to know what settings to have the meter on also please could you explain where I need to put the wires on the coil/other and what wires please.

need to set a 009 @ 28 BTDC @ 3500 RPM as got a 34 pic carb on.

I am right in thinking the 009 should be set at this.. yes??

Thanks

Nope, not unless you've got a stupidly expensive one with huge amounts of additional features :)
that would be the one I have then;)

If your multimeter has such a function, it'd be in the manual, since it's not a standard feature there's no way for me to advise!

Sorry cant help my multi meter has an inductive pick up lead that i just clip over No1 plug lead (the same as a timing light)
Cant you use it the same way as you test the dwell angle, go across the coil?

Have you tried

a) checking the manufacturers site for a manual
b) not being cheeky to someone who's trying to help.

Only an 'automotive' multimeter would have the RPM function, even the very expensive Mains testers don't have it.
BTW, set a 009 at 30 degrees BTDC, at 3500 RPM

Thinking about it ..it your multimeater dont have the tac sighn on it and no way of switching from 2 3 4 6 12 cylinders ..it would only be able to give you voltage at the coil and thats it

Yeah, it's max 32 degrees, at "Full Advance", but Full Advance occurs at different revs depending on which day of the week each 009 was thrown together in the factory. At 3500 RPM, even the Rejects should have achieved Full Advance, unless they have rusted up inside. :lol:
On a camper, it's safer not to exceed 30 degrees, to protect the engine.

ok matey cheers will set at 30 at 3500 rpm unless anyone else says other.

If I had an advance timing light with rpm function on I would be good to go..thought I could do easy on a multi meter.

Actually you can get "adapters" for multimeter's with frequency counters, friend of mine used to have one years ago though if i remember rightly the multimeter cost the earth!

You could always get someone to increse the engine revs whilst you strobe the pully when it stops advansing then set the timing

That would have been my suggestion too, stick the timing light on it and rev the engine till it stops advancing, you then know it's all in and set the timing accorfingly.
