ok know i got this multimeter for christmas, and i know i cant expect too much from it for the price etc etc, but has anyone had any experience with using this particular multimeter using the rpm measurment using the inductive pick-up because as of at the moment i cant get it to work any ideas

I've honestly never heard of a multimeter with rpm.. i want one now tho

there is but this one doesnt seem to think so

Check that the INDUCTION Pick-Up leads are in the correct sockets [Holes] and then:-
The Rotary Dial has to be at the correct position,
Probably pointing to something like "RPM" "REVS" or the like.

Then the Clamp goes over ONE of the Sparkplug leads,
NOT the Coil lead like someone did

yep yep all fine, might try it on the lawn mower sometime and see if thats any different, you can choose between 2 and 4 stroke

Ive got one right here, had it for a while with no problems. I haven't tried the tacho part though. You should just have to turn the dial to the left to x10RPM Then the readout should show RPM followed by three digits then a small circle with either 2 or 4 in it for 2stroke or 4 stroke. You change the 2 or 4 by pushing the red button on the top left. Then plug the black lead to com and the red lead to the right hand socket then put your inductive sensor on a plug lead and it should work.
Just read my instruction manual and it says if no reading is recieved, unhook the clamp,turn it over and connect again.

yep yep done all that, when i have it all connected and turn the multimeter off and turn it back on it starts reading then after a second it the numbers start to go back down to zero, thanks for your reply
if you wouldnt mind could you please test yours to see if it works thanks

I just went out and tried my tacho and it works on the RPM setting, but only showed about 350 RPM at 1500 RPM when it was on the X10RPM. It looks like the RPM setting is for up to 3000RPM. It only worked with the inductive pickup sitting with the bit that opens to the top. I found that the tacho was slow to react when i gave it a rev, but would eventually show a true reading if i held the revs at a constant speed.

ok thanks heaps for that, what did you have the sensitivity set at on the pick up, did you have the spark plug lead sitting up against the pickup or in the centre of the hole not touching it, if you know what i mean

[Tree cutter]

I tried the sensitivity on both low and high and it worked the same on both settings. The plug lead was running through the centre of the hole and not really touching the pickup

ok i'll give it a go, thanks

i tried it on our lawn mower and it worked but it still wont work on my parents toyotas, go figure

[Tree cutter]

The insulation on the toyota leads must be pretty good so your multimeter cant sense a pulse. I tested mine on my Hilux but it has Bosch leads. At least you know it works

i tested it on our avalon 3.0 v6 and hilux 2.7 i4, which have pretty thin/solid feeling leads so maybe yeah its just shielding the impulse
