When building a new coil, does it have to be tested with liquid on it, or can it be tested dry? I see videos where someone puts it on a battery to test dry, and I read somewhere else it needs to be wet.
Thanks in advance!

If you are testing with a dedicated ohm-meter then dry is preferred. They only put a very small voltage through the coil.
If you're testing with your vv/vw device that has a built-in Ω display, you may want some liquid there so you don't get a burnt taste when you finally use it

When you are new to building your own coils, you should have a dedicated ohm reader or a digital multimeter. This can be done when the atty is off of the battery device. If you happened to have made a sub-ohm coil by mistake, the ohm meter on a regulated mod may not be able to measure it, or recognize it as a defective coil and display "LO" or an error code.
Once you are more familiar and experienced making coils, and have a set routine of the same wire gauge, number of wraps, etc, this is not as critical. However, its still necessary to measure the coil resistance to assure you won't be pulling more amps from your battery than its amps in continuous discharge rate. Use the Ohm's Law Calculator to confirm this.
You don't need to put e-liquid on your wick/coil until after you've checked the coil for shorts and an even glow across the length of the coil.

Are you sure you're not thinking about pulsing to find hotspots? If that's the case, you just can't do that dry with cotton.
So the correct answer is "it depends".
Are you testing with an ohm meter, are you testing with your PV, is there a wick in the coil, what is the wick made of ..... pant-pant, can I catch my breath before I go on with the list of things that will change the answer?!?

No u don't need to have wick wet to test coil ohms (silica). I use my Provari most my builds, I have a meter also. The coils may light up sort of one after the other on ur first or second firing. After which they should all light up simultaneously.

I am testing with a PV - VV gripper and MVP2. Yes, there is wick in coil - silica.
What else?

If you are using an ecig battery to check the ohms then you should put it wet; your ecig battery isn't really a tester and probably expects a wet coil. You battery might be putting out high current and if the coil is dry it is possible your coil could get burnt out.
If you are building coils you should have your own multimeter and use that to measure ohms; measuring ohms does not need wet.

Ok, I got a Klein MM200 multimeter. Is this good for testing dry coils? It is difficult to hold the leads in the appropriate (+ and -) places.
Thanks!
Thanks!
Sounds good; guess you could use some aligator clip wires too; hadn't thought of that; I usually have those.
Using ur PV to meter your builds is fine as u get started. I know u mentioned u bought a meter also which is good. When building with silica IMO u should measure, adjust and test burn dry. It will allow u immed visual results as wetting will force u to burn off the juice first to see if ur coils r glowing evenly. I set up my KF using silica and on top of my Provari every time. I use the PV to double check my build. I've built it this way for a year but still always meter it out. U should visit the RBA section, lots of info.

I test on a vamo normally dry then test fire cover with juice then do it all over agin
I'll check it dry, test fire it at low voltage to make sure it glows evenly, wet it down, check the ohms again, test fire it again, THEN fill it up and put it next to my face....
The extra checks may take all of 30 - 60 seconds.
