Yes. I believe you need to go into EScribe and the material tab, you can add Ni200, Ti, and SS. Then upload to your device. Remember to download your settings from your device first (normally it does this by default, but you can turn this off), or all of your settings will be lost.

Thanks.  Getting closer.  Guess it's not a loose connection. 

The theorem seems to want a very high temp, but it's reading the temp properly.  I have some other SS wire coming and some Ti and Ni at home.  I may play around.  I think I'm getting there though.  Lots of cool changes to the Firmware.  Pretty awesome!

I've been testing some Wismec SS Notch coils using the DNA200 and 75.  They are pretty straight forward in Power mode and perform as expected.  In Temp mode... well that's another thing...

Here is a bit about the Notch Coil:

[clear1x1]
Replacement NotchCoil - Pack of 5 for Wismec Theorem or Rebuildable Atomizer

The Stainless Steel 316 NotchCoil is the latest technology from Wismec which may be used in both wattage and stainless steel temperature control mode. Ready to be installed in your favorite RBA/RTA!

The NotchCoil is the same one found in the Theorem Atomizer, designed by JayBo Designs and inspired by "SMM"

Features and Specs:

  • Ready to be installed in your favorite RBA/RTA
  • Stainless steel one-piece design
  • Provides great flavor and vapor similar to a Clapton wire build
  • Can be used in Wattage (Power) or Stainless Steel temperature control mode
  • Consistent evenly heated surface area
  • Perfect for low wattage builds
  • Includes organic cotton
  • Inner diameter 4.8mm
  • 0.23ohm
  • Non-resistance +/- Leads
  • Very fast ramp up time
  • Easily rewicked
  • Pack of 5 - Wismec NotchCoil with Cotton

In Temp mode the coil performs as shown in this screen shot:

I'm wondering why the temp is not more smooth and the temp is fluctuating so much?  (SS316 material setting used) Could it be that a "notch coil" specific TCR is needed.  They heat very quickly and cool quickly thus that could account for the performance as shown in the graph.

Thoughts or experience from others welcome.... [smile]

Have you tried SS316 wire and compared? Or is this the first time you have used SS?

Nope I've not used SS wire as I like simple, fiddle free vaping and use pre-made coils only.  Maybe some who use SS can post a screen shot of Device Monitor for comparison.  Does the graph I posted resemble SS built coils as far as the temp regulation pattern ?  It is a good vape...

Yeah I am not a big fan of SS and I had a very bad experience from it with smell and taste I may go into later. But since the TCR value is so low for SS, the resistance changes far less in regards to temperature than other TC types. Although I just got an idea and I think if the wattage is set slightly too low, it might smooth out.

Yes it works like I thought it would. Here is a SS316L single coil set at 20 watts on the left. Changed it to 5 watts. See how it smooths out?

The Notch coil has a lot of mass (surface area) ....  strange animal in temp mode.... I've tried many different temp, wattage, and preheat settings and when the vape doesn't reach set temp it is pretty smooth but a setting that reaches temp setting gives a very different and less smooth graph after it gets to temp...  I contacted Wismec last week but no response yet.... 

THX for your interest.... will continue to play with this animal.... [rolleyes]

What does your Device Monitor show now? I switched to Power Dominant and regulating temp by the wattage instead of the temp. So it is like running SS in power mode except you have the extra TC benefits. I am MTL this SS316L and I set the preheat (I turn it off when using Temperature Dominant) to 20 watts for 1.5 seconds. And maxed out the punch. And this is how it looks now.

If you noticed, my SS316L coil does and acts the very same way as a Notch coil. I don't think it is the Notch coil, but SS in general. The DNA200 plus everything else I've used over compensates trying to adjust the temperature if the wattage is too high. Other wire types like nickel isn't a problem at all. Here is one of my nickel coils for an example.

Yep, all my nickel coils are spot on too....  when I cut the wattage down to 15 watts:

And at 10 watts:

put the same SS notch coil on a DNA 75 and look at the difference between how the 75 handles SS temp regulation and how the 200 doez it. the 75 uses a softer TC control system/algorithm whereas the 200 is crazy punchy. i tend to run all my SS builds on my 75's and all other wires on my 200's.

dna 200 ss 316L (no, cell 1 isn't really higher than 2 and 3. just appears that way.)

OK.....  the DNA75 is the bomb for the notch SS316 coil....  smoothed right out compared to the DNA200.....  maybe a firmware update is in the future for the DNA200 but I'm pleased to use the DNA75 with this notch coil....  THX @ChuckyButt200 and @BillW50 for working thru this issue to a happy conclusion....  [thumb]
