How to see if your atomizer is truly dead with a Voltmeter

Brilliant, works like a charm. Thank you very much.

CJsKee;

4 ohms should be OK on the attys. Each brand of atty is different, and the ohms readings will vary.

Jim...Thanks much. I set the dial on 2000 (to get a zero reading when I touched the probes together...actually 003...cause set at 200 I got a "1" reading) and the good attys read 7. Now then...I figure this would really be 3.5 if the meter worked on 200 so I hope this is right.

I think I'll run right out and get me one of them Fluke 125 scopemeters

CJ if i understood the instructions right, when it shows 1 you need to move it up one setting on the dial, like it can't display properly and the reading is higher than the current setting allows.

i had issues with that adapter going to 0 as well, i turned it off, touched the probes together, then turned it on and touched them again, it helped clear it to 0 like it was supposed to.

My new HF voltmeter came in today and I did what you said but I can't get mine to go to 0. What is your set on? I tried 2000 and 200. Can't get 0.

Stormy...I set mine at 2000 and finally got a reading of 002 or 003 when I touch the probes together. I think someone said that this was close enough.

I am good then thanks. Mine jumps around a lot but finally settles down to 002. I guess that is normal.

Don't care about Ohm values, maybe temperature dependent (PTC heaters in some models), just use the "conduction check" mode of Your multimeter and listen for the beep.

Be careful with butteries, they may explode when short circuit'd!

I had 2 attys that tested off the chart. After soaking them for 2 days (1 in cola and another day in Everclear) they still wouldn't fire and still had huge ohm readings. I hooked them up to 5 volts DC with a model train transformer - well they both glowed for a split second b4 they popped.

Doesn't always work that way. Sometimes the contaminated deposit will complete the circuit, giving you positive continuity. Your continuity check will beep even though the coil is broken.

Well, I don't know to what level nowadays Chinese manufactured conduction testers of multimeters are set?

How to use an ohm meter.

* Put it to the lowest resistance setting
(Note: some are continuity checkers at the lowest setting and there is a function button. This is so when you touch the red & black leads it beeps)
* Touch the red & black leads together.. it says 0 ohms. (or 0.4 etc)
* Get a mechanical pencil or shave off then end of a regular pencil to expose more graphite.
* Put the leads about 2cm apart both touching on the black graphite. It should read 1 to 8ohms or something.
* Now measure the atomizer with no batteries involved.
* If it isn't 3 to 4ohms, then click the scale knob/button to 1K (2K) or autoscale
* If it is 30ohms then it will only get 1/10th as hot.
