Welcome to ECF...
buy a DMM, and test from each negative post, in turn, to the center positive post.

you could take a multimeter from homedepot and connect a test lead to each end of the individual coils to see but i usually make 2 coils with same number of wraps on the same drill pit and call it good then test total resistance
That's hard to do and IMO not really necessary. Check the resistance between the posts. If you've made the coils with the same number of wraps, of the same inner diameter, used the same gauge wire and the tails are the same length, each coil will be very close to twice the resistance the meter shows you. If one coil is a few percent different from the other it really doesn't affect your vape much.
I've used a dual coil Trident a lot the last year. I once wrapped one coil with 8 wraps and one with 9 by mistake. I could see they were not the same when I dry fired them. The 9 wrap coil took noticeably longer to heat up than the 8 wrap. I was lazy, left them and vaped it. I was quite happy with the result.
If coil heat up time is about the same, they are pretty close to the same resistance.
Vape on
