Vaporshark dna30 flashing ohms symbol

[Grandad]

Hi all
Ive treated myself to a Vaporshark dna30 (wifes gonna kill me) arrived today put my Erl on it with a 1.3ohms microcoil in it when i fire it at 7W the ohms symbol is flashing showing no volts and im starting to get a burnt taste.

So i put my Kayfun on it with a 1.6ohm microcoil and exactly the same as the Erl.

I had a read up and it says that 1 ohm or below it may flash insufficient power but im getting the burnt taste so shorly its to high.

Sorry the box mod is all new to me any help kindly appreciated

it flashes when you have wattage too low for the coil, just click up a few notches and it'll eventually stop flashing (you can still vape it, regardless ) I always assume its just a hint and tips setting? only mine does that all the time too.....

Mine doesnt show voltage when i'm in wattage mode - or vica versa. I again assumed that its the chip settings - I know what you mean though as the isticks and cheaper mod display shows... confusing but I think its normal <<or I have your twin here>>

Mmmmmm confusing ok so ive turned it up and bloody hell it stopped flashing and more clouds than in the sky now woooo.

No mine still dosent show voltage but just checked on my IStick that does, These are a lovely little mod quite heavy for its size and NOW a great vape.

Im using .25 kanthal for my microcoils would it be worth stepping up to .28 Pepperty

Thanks for the quick reply

Grandad the dna30 has a min output voltage of 4 volts so with a 1.6 ohm coil the minimum wattage setting is 4*4 / 1.6 = 10 watts

With a 1.3 ohm coil the min wattage is 4*4 / 1.3 = 12.3 watts.

So with either coil you can't vape at 7 watts and the flashing display is telling you your desired 7w setting is not possible and the output is actually higher.

Pepperty is correct, if you want lower watts you will need a higher ohm coil, as the battery drains it will go slightly lower as it's bottom limit is dictated by the battery voltage. You should see the volts when it's firing.

Thankyou Greg VapingBad i was being a bit cautious with the watts but just cranked it up to 10 watts wow these things are amazing, why have i not bought one till now

How did you work out what watts you require Greg i strugging with the ohms law thingy

Workings above Grandad

wattage = voltage² / ohms

Or Grandad do what I do because I don't know the math formulas either, use a Calculator

Sorry to sound thick but cant see how you got them figures Greg

So in your min voltage is 4 V and you want 7 W using R_min = V²/Power = 16/7 = 2.3 ohm, but that will not be able to go to the highest power setting as you will hit the upper V limit. 1 - 1.5 ohm is a good resistance for a DNA30 1 ohm is 16+ W ans 1.5 ohm is 10.7+ W.

I think that may be easier for me @letsavit

Oh my goodness so if i stick around the 1.5 ohm im no im good for 10+ watts 

Thankyou VapingBad much appreciated

Yep if your struggling with the maths / formula just use the link @letsavit posted 

what wattage are are you wanting to vape at Grandad ?

Grandad we are saying at 1.5 ohms you can't go lower than 10.7 watts but you can go higher

It is in this day and age yes, these two clever clogs will have you using a abacus next.....


Im sitting in front of a 15k calculator right now (CAD machine/software) working, im no good at math, I know what to enter and where and let my work tool do the rest for me.....
