I've posted EScribe 2.0 SP8 as an Early Service Pack.

We're testing it at present. Shouldn't be too long unless we run into any bugs.

You should still be able to lock it fine if you upload that from EScribe.

Good catch. It looks like altering it on the device (as opposed to via EScribe) doesn't trigger a save, unless the material or Ohms change. I'll have this fixed for SP8.

Still working on SP8.

Just make sure to leave temperatures under 150F or so alone. They are used for Cold Ohms correction as well.

What firmware Service Pack are you running? By the way, EScribe automatically saves settings which would include your theme. Go to Help -> Backups. If you used Theme Installer, Theme Designer will have the backup (or the Backups button of Theme Installer).

Have you tried removing the batteries and putting them back in? It could have been caused by a communication glitch with the screen.

Alter the material curve, keeping in mind resistances will be normalized around the 70F value. For example, if the working range for your test is 600 to 800F, look up the ratio of resistances to the 70F value. Then put those values for 400F to 600F in the curve. Then if you set it to 500F you will get 700F etcetra. By shifting the curve you will shift the readings but be able to go over 600F.

This is a bit of an odd question I know, but by any chance, were the ones that didn't detect connected to your computer when you powered it up (and the ones that did work, not connected)?

Hello @Nobbi. Thanks for finding this. I've fixed it and it will be working again in SP8.

Most likely this coming week.

On a Label field, go to Action -> Set... and choose Reset Statistics. If the Puff Count field is Since Reset, Reset Statistics will reset it.

I've posted EScribe 2.0 SP7 as an Early Service Pack. It does not contain a device Service Pack for DNA 75 Color (that will be SP8), but I did unify some code between the MacOS and Windows versions, which sped up Windows EScribe Suite significantly and fixed some Theme Designer bugs on MacOS. Also, for manufacturers, Production Utility can now program and test multiple devices at the same time (use "Automatically Program and Test on USB Connect").

There is a Reset Statistics action in Theme Designer. Make sure your theme is using Statistics -> Since Reset -> Puffs, not Statistics -> Total -> Puffs.

@jhdelamain sent his mod to us so we could reproduce the bug. I have found the cause. It will be fixed in the next device Service Pack. You do not need to send your device to Evolv.

The ranges are for 75W operation. Outside the ranges, there are cases where you may not get the full 75W at all times, but it should still operate fine. Minimum resistances are due to the current limit: Pmax=Imax^2*R Maximum resistances are due to the voltage limit. Pmax=Vmax^2/R The data sheet's temperature-sensing coil graphs are for Nickel. For Stainless, the range is closer to the Kanthal graph.

Does the theme use Puffs -> Total, or Puffs -> Since Reset? This is a fairly common bug in themes.

What is it doing for you when charging from the wall? The USB Charge Current on DNA 75C is an estimate based on USB Voltage drop, since (like a DNA 75 but unlike a DNA 200 or 250) it uses a charger chip instead of on-board charging, so we don't have any way to read the current directly. The estimate works with many chargers, but not all. We mostly use it to improve the case thermal modeling.

In EScribe, the "Temperature Coefficient of Resistance (approximate)" option has a minimum TCR that it allows to be specified. This is essentially an editorial decision on my part -- below a certain level, it's just not going to work well. The firmware of DNAs has no such restrictions, so you are welcome to upload any monotonic curve, and it will happily *attempt* to control to it. It will try. As an aside, here are a few reasons that controlling very low TCR can't work well: The smaller the resistance change, the more other parts of the system will distort the accuracy of the result. For example, some stainless steel atomizers have nickel legs. Suppose the nickel legs heat 20F. If the legs are a tenth of the resistance, stainless has 1/6th the TCR of nickel, so that's going to measure as if the stainless steel has increased 20F*(6/10)=12F. So as the legs heat up, your vape gets 12F colder, even though the coil is staying the same. Suppose the material you chose has 1/60th the TCR of nickel. That's going to be a 120F distortion. As the TCR gets smaller, this kind of problem gets bigger. Even copper wiring has a TCR. Sometimes screwing in an atomizer slightly differently can shift its resistance some fraction of a percent. If (say) 400F is 1%, how can you hope to get the vape consistent? There's an electrical noise problem at a certain point. Suppose you have a 1 Ohm atomizer and can read to 1 mV / 1 mA. At 25 watts, it's 5V, 5A. If (say) 400F is 1%, 1.01 Ohms is 5.025V, 4.975A. You've got 25 values between 70F and 400F, so a single bit of electrical noise on either voltage or current will be 13 degrees. That's going to be a rather bouncy vape. etc.

This will happen if the battery is not connected / making contact. It bounces like that when it is powered by USB only.

I'll be looking into this in the coming week.

Yes. Go to the Theme tab, Theme Designer, Appearance tab, Fading.

I've posted SP6.
