Temp warning will be displayed

[nicoparkk]

Hi. I'm using a clone Billet Box DNA60c.

There was no problem when I usually used 0.8 ohm 20 watts for MTL, but Temp warning is displayed from about 25 watts when 0.28 ohm is signed to the steamshell.(Watt mode)

It was the same when the same coil was used on different bridges.

Is there a problem with my chipset?

Would you post a snippet of your device firing in Device Monitor like this one of mine?

Maybe include you board and room temperatures in your post as well as your coil material.

@nicoparkk Check your coil. No problem with your chipset.

I used pmc coil 0.28 ohm and it worked fine on other instruments.

Mod Resistance was set around 0.15, as the displayed resistance value was held higher than the actual resistance value.

Is it related to this?

Never heard of this coil.

What 'mod resistance'? Are you talking about escribe -> mod -> electrical -> mod resistance?

The left side of your screen looks nothing like the right side. 

Left side shows: 16watts, 0.984Ω coil.

Right side shows: 31watts, 0.219Ω coil.

Battery voltage drop while firing looks terrible.

 

If that is a .28Ω coil, re-measure the resistance of the coil on the mod.

Yes, that's what you said.

I've already broken up the bridge.
So that's what happened to get the recorded data I wrote yesterday.
The right side is the data that had the problem.

What should I do to solve this?

Your battery voltage drop.

Either your cell is really weak or there is a poor connection between battery and board.

If this battery works well in another mod then check that it's tight enough against battery contact. Check all battery connections are clean.

With a load of 27 - 32 watts I would expect to see voltage drop to about 3.8 volts or higher with a cell that's nearly fully charged.

Your mod resistance of 0.15 ohm is way off from what would be expected, how did it get set to that?  Default setting is 0.004 ohm so actual measurement shouldn't be very far from that. I can imagine something like 0.012 ohm but not 0.15 ohm  

[nicoparkk]

 

Initialized all settings.
I don't think the battery is the problem. I'm using it normally on other devices.
BATT warning was added to my symptoms in addition to TEMP warning.
I tightened the drip tip loosely and it ignites, but something is off.

It works normally when using 0.8 ohm coil for tmd boro.

Is there a problem with the contact point?

What manufacturer makes this? Post link.

So is that a hand wrapped coil in an RBA or a stock coil in a bridge?

Did you change "mod resistance" ? How did it get to 0.15? And what is it now?

I need you to use 'escribe' words.
What do you mean by "Initialized all settings." ?
What do you mean by " .... something is off." ?

Finally, I'd like to see a FULL Device Monitor screenshot like DWCraig posted way up top, with only these 5 parameters clicked.

 

[nicoparkk]

Sorry, wrong words because I'm using a translator.

The manufacturer is JHFWI.

This coil is a fused clapton, handcrafted coil.

Initialized all settings -> Restore Defaults

This data is when the drip tip is loosely tightened.

When tightened, the BATT warning is on display.

Thank you for all that you cleared up. 

Yesterday your Device Monitor showed differently to today. When you pushed the fire button, the voltage dropped (as it should) 

Today when you pushed the fire button, the voltage went up, no sag (which is backwards/odd/wrong) and it shows your coil losing resistance while it should be staying the same or increasing.

Yet you say your 0.8Ω stock coil works fine.

Do you have any other RBA's you could try in this mod OR any other DNA's you can try with this RBA?

That drip tip should always be snug, not superman tight.

[nicoparkk]

I only have one device. I used a different rba.

I used a ni80 fused clampon and 0.55 ohm was measured on the ohmtap.

Why is there a resistance difference between Omtap and dna chipset?

It works good. I can only think that there's a problem with the pmc coil.

But when I bought this from shop, I saw rba that had my issues working normally on other devices.

That's why I'm asking you for answers.

[Wayneo]

That DM screenshot looked much better.

AGAIN

I believe you started with a SteamShell RBA. What RBA did you use for the above?

Yes. When tmd boro was used, the ohms of the device were displayed about 0.15 higher than the coil.

So I adjusted mod resistance, but now I'm back to the default setting of 0.004.

This rba is also steamshell.

[dwcraig1]

So now is the live ohms higher or lower than the cold ohms in Device Monitor when firing?
