Atomizer short?

[Rumi]

i could only find 1 video that showed an atomizer short which said to hold black lead of multimeter to the threads then push with the red lead on the bottom of the positive post and if your numbers jump you have a short. So I recoiled my patriot clone rda and tested with the meter before hooking to a mod, no big jumps in the reading. However what made me suspect a short was the previous build was showing crazy hot legs and uneven glowing on a parallel build and my usual fixes for these problems did not help. How can I safely test if it is shorted? The hot coil build was on a mech mod so should I throw that battery away for safety? Can I test the atty on my dna 40 device safely since the chip should protect the battery and read atomizer short or some other error reading? Would the multi meter tell me if my battery was shorted and venting? What would it read? I have only checked the volts on a battery with the meter.

Your meter, when set to the "Ω" scale should read infinite (∞) resistance (or sometimes a high and variable megaohm value - which is the "jump" you refer to) with no coil in place... and the build net resistance when coil(s) are attached.

However what made me suspect a short was the previous build was showing crazy hot legs and uneven glowing on a parallel build and my usual fixes for these problems did not help.
Loose terminals (Kanthal will compress and the screw torque will be reduced - in turn causing inconsistent heating and/or net resistance to increase), damaged and/or stretched wire at tails and/or not using genuine Kanthal wire (mystery metallurgy - Chinese crap)... are a few possibles.

How can I safely test if it is shorted?
My first sentence above is the test. The term "shorted" means the positive terminal is no longer insulated from the negative (ground) atomizer body... but instead a electrically conductive pathway exists, being "shorted" to that ground.

The hot coil build was on a mech mod so should I throw that battery away for safety?
I don't see why... unless you kept it fired for an extended period of time with a build net resistance too low for the batteries MCCD rating.

Can I test the atty on my Dna 40 device safely since the chip should protect the battery and read atomizer short or some other error reading?
I suppose... but unless you've got a crap $10 DMM with crap test leads, there's no need, as the meter is protected by a fuse.

Would the multi meter tell me if my battery was shorted and venting? What would it read? I have only checked the volts on a battery with the meter.

Which is the only straight-forward, "safe" measurement you can obtain. If you set the DMM to the Ohmmeter to test a battery, you'll pop the fuse. To test battery resistance with a DMM, there are a variety of safe methods.

I use an ohm meter.

the insulation is my suspicion, so I should test it negative on thread and positive on post without a coil and read "00" meaning no short or jumping numbers would = short?

Ok that didn't make sense to me dumb it down please. I tried this test with no coil on suspect atty and one that works fine and meter reads o.l at rest then numbers jump crazy when leads are applied to threads and pin. Don't I need a coil to complete the circuit?
