I assume you have a vt200 and have downloaded describe?

Me too. Oops

The hcigar vt200

Nah I'll keep it this way till it finally dies.

Thank you!

These are the closest thing i could come up with scouring the internet. /topic/67353-topic/?do=findComment&comment=906184

Thank you for the info guys.

While I initially thought the same thing, after some experiments and reading the escribe manual about the case analyzer. The statics in the thermal section in escribe describe how the board temp is effected by the thermal properties of the case. Yes, blowing on the board would result in the board computing that as room temp going down, because it thinks that if the board temp is being cooled faster than whats expected for the estimated room temp, ergo the room temp must be lower. This is why getting an accurate measurement on the case analyzer is important for the board to calculate an accurate estimate.

No the battery is good and balanced. I think black lace is correct. I wired an external button and it works fine. Strange that is turns on the device every single time but wont fire.

VT200. I've been considering an add on button. just strange that i can pull the batt and it powers on every time but wont fire.

No. The fire button will only turn on it wake the device but not work after boot.

The fire button will wake the device and device monitor has no problem firing the atty, but pressing the button does nothing. I'm inclined to think the button is fine, other wise it would not turn on when pressed. My device is also locked. Updating firmware, downgrading firmware, soft reset, hard reset, and restore evolv defaults does not change this status. Even after clearing all this the device is still locked. I would think rewriting the firmware would wipe everything, but it seems not to be the case.

These are the escribe files I have for the VT200. They are the closest to manufacture settings I can find on the net. If anyone has better defaults than these please contribute. VT200_Defaults.zip

I have run the case analyzer 4 times on the VT200 and have gotten drastically different numbers each time. The only time my room temp is accurate is when first powered on from stand-by, when the board is room temp. My question would be what are the correct conditions for running case analyzer, and what is a tolerable variance for calculated room temp and actual temp? First, I would assume stable room temperature and no air flow. What are the tolerances for this test? Short of putting my mod in an insulated box with a thermocouple. Or is this just having different thermal properties in a given environment at any given time? I'm starting to see why manufactures are not filling in their default settings for at least the case. Is 5°F to 10°f ± acceptable? Is estimated room temperature just there to get a ball park number for temp control or is something like 1ºf needed. obviously the more accurate is better. Am i just overestimating the needed accuracy and this is just splitting hairs? I understand this might be the best Evolv can do with one temperature sensor on the board and that the VT200 thermal properties might fluctuate very widely in different conditions and mod to mod. I would imagine maybe a plastic or wooden case might have more stable, more predictable, variables. Or maybe the other way around, would heat sinking the board to the case help or hurt this? Sorry, I know this post is long and not the best format. I just want to understand the best I can, and have the best device I can. PS What is F/A? Fahrenheit per area,amp charge, or something else?

I have found that the cold ohm's is the normalized Ohm's at 70F. Raw Value = Live or current resistance with no compensation. Normal Kanthal = Raw Value minus Mod's resistance. Normal Temp = Raw Value minus Mod's resistance with some algorithm to give the coils best live estimate of coil. The constant measuring of Ohm's Heats the coil lightly. Kanthal would have no real measurable change with such small heating, but temp control coils it is measurable. The difference here is to compensate for that minute heating. Cold Ohm's = Estimated resistance at 70F In short, the normal ohms is the best attempt to give you a correct live reading of coil resistance without the mods resistance factoring in. Mods I'm 98% sure this is correct but would love conformation.
