So I'm recently new to mechanical mods and RDA's along with the sub ohm world, I understand all the rules and risks when it comes to sub ohming. (Wanted to stated that before I continued.) I have a vamo v5 which I use regularly to check the Ohm's of my build along with the volts of the batteries I'm using, me being afraid of how inaccurate the Vamo V5 is when checking ohms made me go out and buy a multimeter to check the ohms of the coils I was wrapping. I would put the multimeter at its lowest setting (200) and put the positive probe on the middle post screw then the negative on both the negatives screw (and in the juice well between the posts) but I'm getting weird results.
My vamo is showing that I wrapped a .5 dual coil but when I check the ohms of a negative + positive post its around 1ohm each. So to my knowledge 2, 1ohm coils should be right around .5 ohms together, but after taking the internal resistance of the probes, its .3. So why is the actual resistance .5-.3=.2 on the meter, but .5 on my vamo? Also, is it best to take the resistance from the juice well in between the posts or on the actual posts?
