  1. I've been thinking about this for awhile. Not to suggest that too light of gauge wire was used here on the output but I'd like to know if doing so would fool the board into thinking the coil was hotter than it actually is. My thoughts in this case go towards the 510's solder joints, both on the board and on the socket. If one of the joints were faulty but still good enough to read the cold ohms correctly(no load) would this be the result?

  2. So now what I wonder. I thought maybe mine was skewed due to heavy use running the battery down to low enough to do the test. It sat there for an hour waiting for temp to steady. Mine was done with room temp at 75 F but I'm not sure if it matters as long as you enter the correct room temp. It would be great if John would comment on this subject.

    Case Analyzer:

    Thermal

    The Case Analyzer and/or Device Manufacture specific settings should be used to populate the data in the fields. Manual field entries are discouraged.

    Case Analyzer: EScribe can be used to analyze your case’s thermal properties. This should already be populated with the manufacturer’s settings and will not need to be changed.

    Case Cooling Time Constant: The time for the case to cool 63.2% of the way to a steady temperature.

    Case Heating Time Constant: The time for the case to heat up 63.2% of the way to a steady temperature.

    Case USB Charge ?T: The amount of heating caused by USB battery charging.

    Minimum Ambient Temperature: The minimum ambient temperature this device will ever be used in. Typically this will not need adjustment.

    Maximum Ambient Temperature: The maximum ambient temperature this device will ever be used in. Typically this will not need adjustment.

    In the case (no pun intended)of quite a few of the China mod makers this has not been done so the Evolv settings are in place.

    Thermal results for my Hotcig DX200

    I posted this in another forum that sells these and got this response:

    "...if one is calculating the average temperature of 10 objects in a room, and nine of them are between 20 and 25 degrees Celsius, but the tenth is an oven at 175 °C, themedian of the data will be comprised between 20 and 25 °C but the meantemperature will be between 35.5 and 40 °C. In this case, the median better reflects the temperature of a randomly sampled object than the mean; naively interpreting the mean as "a typical sample", equivalent to the median, is incorrect." 
    Just felt like I had to share that with you. Anyway, your DX200 Case Analyzer Resultsare totally incoherent/inconsistent and out of a proper context to even take them into account by anyone here, or for any point you may had wanted to make with'em."(end of qoute)

    Does anyone see something "wrong" with these figures?
    I must say though that most of the folks in that forum are either anti Evolv or have no idea what it is.

    "Low Ohms" would come on the screen of the mod periodically so I stopped it, will try again with two lamps in series.
    My cold ohms was 0.5 and I had to turn off TP as it went to immediate TP when firing.

    Well I guess I need to learn how to read, the mod's screen said "OHMS TOO HIGH" not "LOW".... DUH
    (tungsten no doubt)

    [QUOTE=robby]Unfortunately you cant get two 1860 batteries to fit, not enough width in the cavity and there doesn`t seem to be enough scope to mill it out etc @dwcraig1 The cavity is only 33mm wide. I`m not a battery expert, but don`t you need 11Volts for the DNA200?


    As I don't have mine as yet I was going by the dimensions listed for the Lion Power 1500 35c. DNA200 works fine with 7.4 volt pack but only outputs 133 watts. [/QUOTE]
