Testing cartomizer ohms prior to filling?

[Anarchy84]

I could waste a carto figuring this out, but I thought someone here would probably know so why do that?

If I put an empty cartomizer on my Provari and use the AO menu to test ohms, will it put enough voltage through the coil to fry the carto? I've been using an ohm meter to test the cartos before priming them, but if the Provari will do it without burning them to death that'd be far more convenient.

Thanks!

I think you better not!!
Why do you need to - just checking for duds?

You'll burn it. It's physically impossible to measure resistance without applying some voltage to it. You'd be better off with a cheap Radio Shack multimeter. I wouldn't think that would create enough heat to burn it, but then again I've never tried. They only use a fraction of what the Provari would though.

Yes just checking for duds.

Yeah, I use a multimeter now. I just don't always have it with me! It does work well though. Doesn't apply any heat to the coil.

It doesn't have to just to measure resistance, in fact for what you want, you don't want it to heat up the coil. Just make sure it's zeroed in & that you have a fresh battery in it.

Don't do that. I know the CB function places voltage across the device and actually fires it during a battery check. I just put an in-line meter on my Provari and it does place 2.35 volts on the device during an AO check as well. You don't want to risk singeing the filler in a dry carto. Not all APV's work like this during battery check or atomizer checks - but the Provari does.

I have one of those digital ohm checkers that I use for this all the time, no problem burning anything with it. I order 20-30 cartos at one time, and I check them all upon receiving them for duds, that way when I grab one, I know it's good to go.

This is why I check attys and build coils on either my SVD or VV V3. They're accurate enough to check ohms, and usually powerful enough to heat a coil while I'm building it to get the hotspots out (unless of course I'm building a sub-ohm on my Helios, but it checks the ohms just fine). After I get a coil built or check a carto to make sure it's not dead, I'll fill it and then test it again on my Provari.

A ”cold” coil will give you a lower & less accurate ohm reading. That's why when you use the AO function on a provari to check resistance on a coil that hasn't been used for a bit, you get two ohm readings. First a lower/less accurate one, then as the coil warms up from the voltage, the second reading will be more accurate to the coils actual resistance.
