The software just needs to be smart enough to reduce the max output voltage based on resistance of the coil...
Volts, Amps or VA's... whichever maxes out first will set the limits.

Looking at the photos, I think it would ignore any coil, as he is measuring at the posts?
You should (also) blog the post, to make it easier to find in the future? Just a thought...
Nah,... you don't get to ignore the resistance... I'm sure all of our wallets would be a little heavier if that were the case... or not... stupid economics
http://www.allaboutcircuits.com/vol_1/chpt_8/9.html said:An ingenious method of measuring the subject resistance in a situation like this involves the use of both an ammeter and a voltmeter. We know from Ohm's Law that resistance is equal to voltage divided by current (R = E/I). Thus, we should be able to determine the resistance of the subject component if we measure the current going through it and the voltage dropped across it:
We know he was measuring 3.7ish volts... and the coil is reported to be 1.3 ohms... so we also know that he was passing about [ 3.7/1.3~>2.846 ] 2.85 amps through the coil, and we know this because you don't get to read beyond the coil from there. Performing a simple sanity check says... [ 3.7 * 2.85 ~> 10.545VA ] Given the equipment being used ( MVP2 in voltage mode set too high for the resistance, DMM, my lazyness of not looking up exact voltage he listed ), I would say that's about what I would expect to see. I figured 1.6 ohms thinking the MVP was spitting out 11 watts in perfect conditions. [ sqrt(11 * 1.6) ~> 4.2V ]
I hope I'm posting this in the correct place. My husband bought me an Innokin MVP 2. I don't understand the 2 buttons. I know they are for voltage and wattage?? I'm using a Kangartech Glass Clearomizers on the Innokin. I've been vaping for almost 3 years but have never played with batteries. I'm sure a lot of this is personal preference but I want to understand how to get that consistent vape. I'm pretty much a creature of habit. I vape a triple menthol juice. Can someone help?

The P and the U are for Power = Watts and the other is Volts but you can't make a V with the screen. Decide whether you want to vape by volts or watts. Which ever button you set last is what it will use. Never both.
Pressing both buttons at the same time gives you the resistance of your coil A with a number, then your remaining battery charge in volts.

Forgot to add that if you press the P or U button you first get the Puff Counter. You have to hold a button down for a bit to get it to change from Puffs to either Watts or Volts.
I suggest using Volts if you had a twist before that gave a number that you liked or Watts if you are not sure. IF your topper is in the 1.8-2.2 ohm range, start with 7.0 watts.

hi Kathy_p, welcome to the club
on the MVP,
--
-holding both buttons:
-first display is, Coil Ωs
-second display is, Charge Remaining in internal battery
- - -
single button operation:
>push and hold (top button) "P" for watts control
>push and hold (bottom button) "U" for volts control
-the first display will always be Puff Counter (0-999)
(which actually just counts how many times you push your Fire button)
-second number displayed is the adjustable setting (v or w)
-- it is EITHER volts OR watts, never both
-- 3 clks off / 3 clks on (puff counter resets to "0" each time)
-- MVP memory maintains until you change it
Vape
HolidaysThank you for the response. I don't know the difference between volts and watts. I know that sounds crazy but that is what I'm trying to figure out. When I press both buttons together, it shows 59
not sure what 59 could be (you must be mistaken) put your glasses on
if you hold both buttons down:
-the first display will show the ohms (Ω) of the coil in your Kanger Clearo (eg: A 1.8)
-the second display shows, how much battery life is Remaining in the battery (eg: U 3.9)
- - -
volts and watts are just about the same - kinda like jelly or jam
not big enuff difference for you to be concerned with; just pick one (volts)
and use it, till you get familiar with usage

OK - Happy Christmas folks! And yes - the MVP v2 is brilliant. It is one of my work horses.
Kathy, the simplest explaination for the difference between volts and watts that I read. Volts is like a manual transmission. If you change to a different ohm topper you will probably need to adjust your volts to get your sweet spot. With watts you set your watts and the circuitry will adjust the volts no matter what ohms the topper is. Clear as mud, eh?
BTW, welcome! Questions? Ask away, great helpful people here!

Rule of thumb :
add 2.0 to your coil Ωs (for ballpark volt setting)
eg: 1.8Ω + 2.0 = 3.8 volts
eg: 2.5Ω + 2.0 = 4.5 volts , etc
- - -
you said your first reading was 1.8Ω, so push your bottom button
and allow volt setting to roll around to 3.7v and see how it vapes
then if you think its not burnt, go to 3.8v for a try (and so on)...
an MVP fault is you CANT go BACKWARDS, you have to always go forward
(around the dial) to get back to a lower setting
ALWAYS start low, then increase power to fit YOUR flavor preferance
Lol! I would probably get it quicker if we compared clothes, or bags or perfume. My thoughts are.....if it doesn't matter, why confuse me with 2 choices? Lol..I'm kidding! I read some of the posts on here and it almost seems like Trig! Measuring, multiplying, calculating! I'm sure I'll find the sweet spot! Thank you for your explanation!

Merry Christmas back at cha !
i guess black is the popular color on the mvp's, discountvapors had 50 of both black and silver 20watts a few days ago, the black is sold out now and there are 42 left of the silver.

I think you might have just pressed one button and thought you held both in and got the puff counter.
