First... you need a digital multi-meter (DMM). How much you choose to spend is entirely at your budgetary discretion.
A word of caution before we begin. Make sure that your meter is set correctly before any test. If you forget to switch from resistance to voltage and apply live voltage, you will pop the fuse in the meter... and unless a spare came with the meter, I doubt you'll have a back-up.
Moving right along...

Once again, I've hit the character limit of 10,000... so a Part Deux is required. Part one... "Steam Engine: From basic use to advanced features" is available, if you started here first.
Heat Flux... and you.
Next, we'll look at perhaps the most ignored, misused and/or misunderstood option in SE... and the reason I wrote all this in the first place. "Heat Flux" (HF).
Heat flux (HF) is a measurement of radiant heat our resistance

This is going long... so get comfortable, and I'll try and make it as painless as possible.
(Hint! If you know all there is to know 'bout SE, save for the heat flux bit... go directly to SE part 2 - Heat Flux... and you.)
Lately... I find myself, far too frequently, explaining a particular aspect of Steam Engine - the variable of "heat flux" - to an ever expanding number of vapists, with questions about wire gauge, net resistance/parallel coil count (or

I've exceeded the 10K character limit in part one... so, here's part deux!
> Addendum 2-17-14:
A coil calculator, developed by ECF member Dampmaskin and called "Steam Engine" (previously called "vape calc") has become available.
It includes not only an ohms law calculator, but a coil wrap estimator that includes parameters like ID, target resistance, leg or "tail" length, "heat flux" (coil temperature values), "heat capacity"

For a long time now, we've seen threads -
"What size are the o-rings on a fill in the blank atomizer?" or,
"What size are the magnets on a fill in the blank mod?"... or the broadest of inquiries,
"I need to measure anything you can think of that might need accurate measuring... how can I do that?"
More often than not, if these inquiries even get a response... it's from a member who owns both the device in question, and a dial
