    May be you misunderstood me, it is exactly what i'm saying : the whole static resistance must be known to precisely estimate the temperature variation.

    I have argued  on the fact that  the 510  connector resistance  (that measured by means of the copper tool) is only a fraction of the whole static resistance. Which is the utility to know only the 510 resistance?

    This threads a good read for those unfamiliar with it. The subject that your talking about seems to begin around here:

  2. If using a non temp wire like Kanthal it will automatically go into power mode. If you want to use a temp wire in power mode there are a couple of choices, turn temp off on desired profile in EScribe and upload to device or scroll through the temp settings on the device till you get to "OFF" and select with fire button.

  3. I am using the latest beta EScribe and firmware, *** 2016-02-29 EScribe 1.0.42 **, it will let me enter .00092. But I have no 316 wire so I can't try it out. It appears to me that the 316 in EScribe is already using that value.
    I must admit that I'm some what confused as I come up with .00088 when using Steamengine.
    Everything seems to indicate that .00092 is the correct value, I'm not sure how I came up with .00088....LOL

  4. While I think an RMA is the best way to go I was still hoping to see the voltage readings taken off the pads where the balance connector connects to the DNA200 board. Just curious if it's a problem with the DNA board or the daughter board. 

  5. So I went ahead and made a couple of Zivipf Nife 30 coils, keep in mind that they are 70% nickel so that yields a fairly low resistance.
    Also the TCR is high so  temp accuracy is easy for the board.
    My coils are 8.5 wraps, 2 mm id, 26 gauge wire, x2, that come out to 0.6? which is a bit lower than I prefer but still doable.
    I really see no real advantage using it over Nife48/52 but it is working well.

  6. Well Zivipf has Nife 30 which is 70% nickel. The listed TCR is 520. Note Zivipf calls their Nife52 48.
    Here is Kanthal's data sheet for Nife70, note the composition. 
    Steamengine lists Nifethal70 (alloy 120) TCR @525
    I assume that Zivipf's Nife30 is Nifethal 120, I have it, perhaps I'll give it a try tonight and report back.
    I'm a big fan of Dicodes nife 30 btw which is 30% nickel (I think)
    Interesting that you posted about it as it was already on my mind.
