Knowing ohms of wrapped coil without mounting on RDA

[Dianhoonho]

Hi guys,

Can I check if you are able to know the ohms of a wrapped coil without mounting it on the pos/neg posts of a rda? Like using a multi-meter or something? Thanks!

You can measure the coil with a multi-meter. There are also some online calculators that will tell you what a certain build will be. That will get you close, but you would still have to measure the actual resistance.

I've used a multimeter with alligator clips to sort of spot check coils.

Hmm...my multi-meter looks like the one below with straight pointy "pens"...

Do I just use each end of the pens to connect to each end of my coil?

Put them on the positive and negative posts of the rda

red is positive

the center post is positive.

positive or negative doesn't matter for measuring ohms. it matters for voltage.

And check the zero offset.

hold the 2 ends together and see what you get; you might not get exactly zero;
whatever you get you have to remember to subtract that from the measurement when you check ohms.

Mmmm...just tried using the 2 metal points on each end of the raw coil itself and I think I managed to get the ohm without putting the coil into the RDA.

Thanks guys...think I was asking a noob question since I should have tried it first before asking.

sure, it is pretty much simple

note - that different gauge or wire or coil type would give you different resistance.
and
the same coil and type should give you the same resistance any time you check it.
